  • C++, overloading std::swap, compiler error, VS 2010

    - by Ian
    I would like to overload std::swap in my template class. In the following code (simplified) #ifndef Point2D_H #define Point2D_H template <class T> class Point2D { protected: T x; T y; public: Point2D () : x ( 0 ), y ( 0 ) {} Point2D( const T &x_, const T &y_ ) : x ( x_ ), y ( y_ ) {} .... public: void swap ( Point2D <T> &p ); }; template <class T> inline void swap ( Point2D <T> &p1, Point2D <T> &p2 ) { p1.swap ( p2 ); } namespace std { template <class T> inline void swap ( Point2D <T> &p1, Point2D <T> &p2 ) { p1.swap ( p2 ); } } template <class T> void Point2D <T>::swap ( Point2D <T> &p ) { using (std::swap); swap ( x, p.x ); swap ( y, p.y ); } #endif there is a compiler error (only in VS 2010): error C2668: 'std::swap' : ambiguous call to overloaded I do not know why, std::swap should be overoaded... Using g ++ code works perfectly. Without templates (i.e. Point2D is not a template class) this code also works.. Thanks for your help.

  • Why is this one div container blocking the other from floating right?

    - by user2824289
    I know the answer is very simple, it's probably one little CSS property, but I've tried to find the solution without asking it here, no luck.. There are two div containers within a div container, and they aren't playing nice. The one is positioned to float right in the upper righthand corner of the parent div, and it won't let any other container float to the right of it. I tried display:inline and display:inline-block but no luck... Here's the code, though something tells me the answer is so easy you won't need it!: The parent div, the upper righthand corner div, and the poor div trying to float right: #um-home-section4 { width:100%; height:300px; background-color: green; } #um-title-right { float:right; width:500px; height:50px; margin-right:20px; margin-top:20px; background-color: fuchsia; } #take-me-there { float:right; margin-top:240px; margin-right:0px; height:50px; width:100px; background-color: gray; } <div id="um-home-section4"> <div id="um-title-right"></div> <div id="take-me-there"></div> </div>

  • How do I make my page respect h1 css addition? [migrated]

    - by Adobe
    I add h1 { margin-top:100px; } to the end of the css, but the page doesn't change. But if I add to the html of some h1: <h1 style="margin-top:100px;"><a class="toc-backref" href="#id4">KHotKeys</a><a class="headerlink" href="#khotkeys" title="Permalink to this headline">¶</a></h1> Then it does.

  • Backquote on iPhone keyboard

    - by lc
    Is there a backquote (backtick) on the iPhone keyboard, and if so, where is it? When I'm writing a post here or on any of the sister sites (especially SO), I want to use the backquote for inline code blocks. Under the single quote key, I've found two curly/angled quotes, but those (’ and ‘) don't seem to do the trick...

  • How to set child unordered list position?

    - by Joel
    Hi folks. I have a nav bar with children unordered lists nested under the main navbar items. My problem is on the inner list, when I position absolute, the inner list is centered to the page, and when I position relative, it is positioning inline with the parent list. I'm trying to get the first child item to line up directly under it's parent. /* OUTER LIST STYLING */ div#navbar2 { position:relative; width: 100%; border-top: solid #000 1px; border-bottom: solid #546F8B 1px; background-color: #546F8B; } div#navbar2 ul#navbar { padding: 0; margin: 10px 0; font-family: Arial, Helvetica, sans-serif; font-size: 16px; letter-spacing:1px; color: #FFF; white-space: nowrap; } div#navbar2 ul#navbar li { margin: 0 2px; list-style-type: none; display: inline; } div#navbar2 li a { text-decoration: none; color: #fff; padding: 10px 10px; } div#navbar2 li a:link { color: #FFF: } div#navbar2 li a:visited { color: #ffffff; } div#navbar2 li a:hover { color: #000; background-color: #FDFFC9; } /* INNER LIST STYLING */ div#navbar2 ul#navbar li ul.innerlist{ display: none; color:#000; } div#navbar2 ul#navbar li ul.innerlist li{ color:#000; } div#navbar2 ul#navbar li:hover ul.innerlist { position: absolute; display: inline; left: 0; width: 100%; margin: 40px 0 0px 0px; padding: 0px; color:#000; } div#navbar2 li.innerlist a { text-decoration: none; color: #000; padding: 10px 10px; } div#navbar2 li.innerlist a:link { color: #000: } div#navbar2 li.innerlist a:visited { color: #000; } div#navbar2 li.innerlist a:hover { color: #000; background-color: #FDFFC9; } And my html: <div id="navbar2"> <ul id="navbar"> <li id="index"><a href="index.php">About Rattletree</a></li> <li id="upcomingshows"><a href="upcomingshows.php">Calendar</a></li> <li id="booking"><a href="booking.php">Contact</a> <ul class="innerlist"> <li class="innerlist"><a href="#">Booking</a></li> <li class="innerlist"><a href="#">press</a></li> </ul> </li> <li id="instruments"><a href="instruments.php">The Band</a> <ul class="innerlist"> <li class="innerlist"><a href="#">The Instruments</a></li> <li class="innerlist"><a href="#">The Players</a></li> </ul> </li> <li id="classes"><a href="classes.php">Sights &amp; Sounds</a> <ul class="innerlist"> <li class="innerlist"><a href="#">Listen</a></li> <li class="innerlist"><a href="#">photos</a></li> <li class="innerlist"><a href="#">video</a></li> </ul> </li> <li id"classes"><a href="classes.php">Workshops &amp; Classes</a></li> </ul> </div> Thanks for any help!

  • Error when starting a tab activity in Android?

    - by ATDeveloper
    I followed the directions verbatim in this Android tutorial, copying/pasting the code from the site to my app. http://developer.android.com/resources/tutorials/views/hello-tabwidget.html However, when I try to run in the Android emulator, I get the error: "The application Hello Tab Widget has stopped unexpectedly. Please try again." I tried debugging by introducing a breakpoint in the first line of the onCreate method, but the error occurs before the breakpoint is even hit. Any idea of what is going wrong, or any other way I can debug this issue? I am using Eclipse.

  • MySqlDateTime to System.DateTime conversion

    - by bowsa
    Ok I'm very new to databases and C# in general, but I'm using a piece of code that exports dataset data to an Excel file, and its taking issue with the date/time format. I'm using the MySQL connector so the rowtype is MySql.Data.Types.MySqlDateTime. Is there any quick way to convert it into System.DateTime so I can slot it straight into the case statement? Here's a link to the code I used, I copied it verbatim so I've not copied and pasted it here. It throws a MySql.Data.Types.MySqlDateTime not handled exception: Code Project Thanks in advance for any help.

  • Plone with Apache Proxy

    - by churnd
    I have a plone zinstance set up through Apache Proxy on OS X Server 10.5. The server is set up with a single vhost on port 80, with Proxy & Proxypass directives to the Plone zinstance: ProxyPass / http://localhost:8080/VirtualHostBase/http/server:80/Plone/VirtualHostRoot/ ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/server:80/Plone/VirtualHostRoot/ However, I have some static HTML and PHP content that I want to display in an iframe via the plone site. I'm thinking I'll need to set up another vhost on a different port, then just specify the port # inline?

  • Incorporating MIT/X11 licensed code into project

    - by Yktula
    I'm rewriting a small MIT-licensed program in C, and I intend to copy a segment from it (though not verbatim) that prints usage information and such things. The programs are going to behave, for the most part, the same, but the implementations are going to be much different. What is the best way to incorporate this code into my program, whether it's licensed under Apache 2, GPLv2/3, or under the MIT license? My guess is that for the first two listed I'd just add the original authors name to the NOTICE file along with relevant information and paste the license header as a comment above the derived code, and for the latter I'd just add the original author's copyright statement above my own.

  • iPhone Advanced table view cells example

    - by Rob
    I have been going through and re-creating Apple's "Advanced Table View Cells" example to better understand everything. I have done everything, but somehow missed one detail and I can't figure it out. If you launch their example (http://developer.apple.com/iphone/library/samplecode/AdvancedTableViewCells/Introduction/Intro.html) and open up the RootViewController.xib file, they have a "tableView" outlet on the inspector that is linked to File's Owner. For whatever reason, I can't get that to show up on my version. My code is almost verbatim of Apple's, so what am I missing? Did I not declare that somewhere or doesn't that get taken from the RootViewController.m file?

  • Manipulate Page Theme Programatically

    - by Aren B
    I've got the following Setup in my Theme: \App_Themes\Default\StyleSheet.css \App_Themes\Default\PrintStyleSheet.css The PrintStyleSheet.css file has a set of printing css rules set in them wrapped in an @Media Print { } block. I need a way to programmatically remove the PrintStyleSheet.css from the list of css files for ASP.NET to inject based on some flags. (Some instances we want to print the site verbatim without custom formatting). I know i could build a seperate theme without the PrintStyleSheet.css in it and switch the theme programmatically, however this would introduce duplication of my master stylesheet which is not acceptable. Any ideas?

  • display:table killing me in IE

    I want to create horizontally-aligned table cells like the ones on this page. I've followed the instructions, and I've even copied the css and markup verbatim, but no matter what I do IE 8 renders my table cells as blocks (stacked on top of each other instead of aligned next to each other). css: <style type="text/css"> body.TableStyles { display: inline-table; border-spacing: 4px; } div.maketable p { display: table-cell; width: 20%; background-color: #cdf; padding: 4px; } </style> markup: <body class="TableStyles"> <div class="maketable"> <p>< prev</p> <p>next ></p> </div> </body>

  • Dynamically register constructor methods in an AbstractFactory at compile time using C++ templates

    - by Horacio
    When implementing a MessageFactory class to instatiate Message objects I used something like: class MessageFactory { public: static Message *create(int type) { switch(type) { case PING_MSG: return new PingMessage(); case PONG_MSG: return new PongMessage(); .... } } This works ok but every time I add a new message I have to add a new XXX_MSG and modify the switch statement. After some research I found a way to dynamically update the MessageFactory at compile time so I can add as many messages as I want without need to modify the MessageFactory itself. This allows for cleaner and easier to maintain code as I do not need to modify three different places to add/remove message classes: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <inttypes.h> class Message { protected: inline Message() {}; public: inline virtual ~Message() { } inline int getMessageType() const { return m_type; } virtual void say() = 0; protected: uint16_t m_type; }; template<int TYPE, typename IMPL> class MessageTmpl: public Message { enum { _MESSAGE_ID = TYPE }; public: static Message* Create() { return new IMPL(); } static const uint16_t MESSAGE_ID; // for registration protected: MessageTmpl() { m_type = MESSAGE_ID; } //use parameter to instanciate template }; typedef Message* (*t_pfFactory)(); class MessageFactory· { public: static uint16_t Register(uint16_t msgid, t_pfFactory factoryMethod) { printf("Registering constructor for msg id %d\n", msgid); m_List[msgid] = factoryMethod; return msgid; } static Message *Create(uint16_t msgid) { return m_List[msgid](); } static t_pfFactory m_List[65536]; }; template <int TYPE, typename IMPL> const uint16_t MessageTmpl<TYPE, IMPL >::MESSAGE_ID = MessageFactory::Register( MessageTmpl<TYPE, IMPL >::_MESSAGE_ID, &MessageTmpl<TYPE, IMPL >::Create); class PingMessage: public MessageTmpl < 10, PingMessage > {· public: PingMessage() {} virtual void say() { printf("Ping\n"); } }; class PongMessage: public MessageTmpl < 11, PongMessage > {· public: PongMessage() {} virtual void say() { printf("Pong\n"); } }; t_pfFactory MessageFactory::m_List[65536]; int main(int argc, char **argv) { Message *msg1; Message *msg2; msg1 = MessageFactory::Create(10); msg1->say(); msg2 = MessageFactory::Create(11); msg2->say(); delete msg1; delete msg2; return 0; } The template here does the magic by registering into the MessageFactory class, all new Message classes (e.g. PingMessage and PongMessage) that subclass from MessageTmpl. This works great and simplifies code maintenance but I still have some questions about this technique: Is this a known technique/pattern? what is the name? I want to search more info about it. I want to make the array for storing new constructors MessageFactory::m_List[65536] a std::map but doing so causes the program to segfault even before reaching main(). Creating an array of 65536 elements is overkill but I have not found a way to make this a dynamic container. For all message classes that are subclasses of MessageTmpl I have to implement the constructor. If not it won't register in the MessageFactory. For example commenting the constructor of the PongMessage: class PongMessage: public MessageTmpl < 11, PongMessage > { public: //PongMessage() {} /* HERE */ virtual void say() { printf("Pong\n"); } }; would result in the PongMessage class not being registered by the MessageFactory and the program would segfault in the MessageFactory::Create(11) line. The question is why the class won't register? Having to add the empty implementation of the 100+ messages I need feels inefficient and unnecessary.

  • how to cout a vector of structs (that's a class member, using extraction operator)

    - by Julz
    hi, i'm trying to simply cout the elements of a vector using an overloaded extraction operator. the vector contians Point, which is just a struct containing two doubles. the vector is a private member of a class called Polygon, so heres my Point.h #ifndef POINT_H #define POINT_H #include <iostream> #include <string> #include <sstream> struct Point { double x; double y; //constructor Point() { x = 0.0; y = 0.0; } friend std::istream& operator >>(std::istream& stream, Point &p) { stream >> std::ws; stream >> p.x; stream >> p.y; return stream; } friend std::ostream& operator << (std::ostream& stream, Point &p) { stream << p.x << p.y; return stream; } }; #endif my Polygon.h #ifndef POLYGON_H #define POLYGON_H #include "Segment.h" #include <vector> class Polygon { //insertion operator needs work friend std::istream & operator >> (std::istream &inStream, Polygon &vertStr); // extraction operator friend std::ostream & operator << (std::ostream &outStream, const Polygon &vertStr); public: //Constructor Polygon(const std::vector<Point> &theVerts); //Default Constructor Polygon(); //Copy Constructor Polygon(const Polygon &polyCopy); //Accessor/Modifier methods inline std::vector<Point> getVector() const {return vertices;} //Return number of Vector elements inline int sizeOfVect() const {return vertices.size();} //add Point elements to vector inline void setVertices(const Point &theVerts){vertices.push_back (theVerts);} private: std::vector<Point> vertices; }; and Polygon.cc using namespace std; #include "Polygon.h" // Constructor Polygon::Polygon(const vector<Point> &theVerts) { vertices = theVerts; } //Default Constructor Polygon::Polygon(){} istream & operator >> (istream &inStream, Polygon::Polygon &vertStr) { inStream >> ws; inStream >> vertStr; return inStream; } // extraction operator ostream & operator << (ostream &outStream, const Polygon::Polygon &vertStr) { outStream << vertStr.vertices << endl; return outStream; } i figure my Point insertion/extraction is right, i can insert and cout using it and i figure i should be able to just...... cout << myPoly[i] << endl; in my driver? (in a loop) or even... cout << myPoly[0] << endl; without a loop? i've tried all sorts of myPoly.at[i]; myPoly.vertices[i]; etc etc also tried all veriations in my extraction function outStream << vertStr.vertices[i] << endl; within loops, etc etc. when i just create a... vector<Point> myVect; in my driver i can just... cout << myVect.at(i) << endl; no problems. tried to find an answer for days, really lost and not through lack of trying!!! thanks in advance for any help. please excuse my lack of comments and formatting also there's bits and pieces missing but i really just need an answer to this problem thanks again

  • Legality Of Re-Implementing An Existing API (e.g. GNU implementing the UNIX APIs)

    - by splicer
    I've often wondered about this. I'm not looking for legal advice, just casual opinions ;) If some company publishes an API on the web for their closed-source library, would it be legal for another party to release an open-source implementation of that API? Are function declarations considered source code? Take GNU implementing the UNIX APIs, for example. The UNIX standard gives the following function declaration and defines its required behaviour in English: char * mktemp(char *template); Now, consider an API that lists and declares and describes several thousand (more much complex) functions, enums, etc.; an API which defines a solution to a non-trival set of problems. If an open-source project publishes C headers that copy (verbatim) the function definitions contained in the closed-source company's published API, doesn't that violate some sort copyright law?

  • Pass page scope attributes to a JSP using pagecontext.include for use in JSTL?

    - by hal10001
    We're using this JSP template solution almost verbatim at work: http://java.sun.com/developer/technicalArticles/javaserverpages/jsp_templates/ When it gets JSP pages to be included, it uses pageContext.include, which leaves us with one problem, and that is that we have a lot of scriplet code that gets initialized in the JSP itself (tag soup). My thought was to modify the template tag with an additional attribute that is a package path reference to a class with an init or execute method. That execute would get called first, and would add page context attributes before including the JSP. We would then use JSTL to access those attributes. However, I was told this wouldn't work because of how pageContext.include works, and the inability to pass through attributes scoped to the page. Is that true, and are there workarounds? I'm so-so on knowing all my scoping rules.

  • Using special characters as keywords in latex listings package

    - by sha
    Hi, I am using the listings package for latex. I am using the SQL language definition and am adding some new keywords that I need, using morekeywords=. I have trouble defining some special characters as keywords, for example, I need [], <, &, and - to be considered as keywords and use the keyword style. I have tried adding these verbatim or with a preceding backslash. It did not work. Your help would be greatly appreciated. Thanks.

  • Rails streaming file download

    - by Leonard Teo
    I'm trying to implement a file download with Rails. I want to eventually migrate this code to using S3 to serve the file. I've copied the Rails send_file code almost verbatim and I cannot seem to get it to stream a file to the user. What happens is that it sends 'a' file to the user, but the downloaded file itself simply contains the text.inspect of the Proc: # What am I doing wrong here? options = {} options[:length] = File.size(file.path) options[:filename] = File.basename(file.path) send_file_headers! options render :status => 200, :text => Proc.new { |response, output| len = 4096 File.open(file.path, 'rb') do |fh| while buf = fh.read(len) output.write(buf) end end } Ps: I've read in a number of other posts that it's not advisable to send files through the Rails stack, and if possible serve using the web server, or in the case of S3 use the hashed URL it can provide. Yes, we really do want to serve the file through the Rails stack.

  • How can I create a custom cleanup mode for git?

    - by Danny
    Git's default cleanup of strip removes all lines starting with a # character. Unfortunately, the Trac engine's wiki formatter uses hashes in the beginning of a code block to denote the syntax type. Additionally any code added verbatim might include hashes as they are a common comment prefix; Perl comes to mind. In the following example the comments all get destroyed by git's cleanup mode. Example: {{{ #!/usr/bin/perl use strict; # say hi to the user. print "hello world\n"; }}} I'd like to use a custom filter that removes all lines beginning with a hash from the bottom of the file upwards. Leaving those lines that being with a hash that are embedded in the commit message I wrote alone. Where or how can I specify this in git? Note, creating a sed or perl script to perform the operation is not a problem, just knowing where to hook it into git is the question.

  • Successive success checks

    - by Stockhausen
    Most of you have probably bumped into a situation, where multiple things must be in check and in certain order before the application can proceed, for example in a very simple case of creating a listening socket (socket, bind, listen, accept etc.). There are at least two obvious ways (don't take this 100% verbatim): if (1st_ok) { if (2nd_ok) { ... or if (!1st_ok) { return; } if (!2nd_ok) { return; } ... Have you ever though of anything smarter, do you prefer one over the other of the above, or do you (if the language provides for it) use exceptions?

  • Templated << friend not working when in interrelationship with other templated union types

    - by Dwight
    While working on my basic vector library, I've been trying to use a nice syntax for swizzle-based printing. The problem occurs when attempting to print a swizzle of a different dimension than the vector in question. In GCC 4.0, I originally had the friend << overloaded functions (with a body, even though it duplicated code) for every dimension in each vector, which caused the code to work, even if the non-native dimension code never actually was called. This failed in GCC 4.2. I recently realized (silly me) that only the function declaration was needed, not the body of the code, so I did that. Now I get the same warning on both GCC 4.0 and 4.2: LINE 50 warning: friend declaration 'std::ostream& operator<<(std::ostream&, const VECTOR3<TYPE>&)' declares a non-template function Plus the five identical warnings more for the other function declarations. The below example code shows off exactly what's going on and has all code necessary to reproduce the problem. #include <iostream> // cout, endl #include <sstream> // ostream, ostringstream, string using std::cout; using std::endl; using std::string; using std::ostream; // Predefines template <typename TYPE> union VECTOR2; template <typename TYPE> union VECTOR3; template <typename TYPE> union VECTOR4; typedef VECTOR2<float> vec2; typedef VECTOR3<float> vec3; typedef VECTOR4<float> vec4; template <typename TYPE> union VECTOR2 { private: struct { TYPE x, y; } v; struct s1 { protected: TYPE x, y; }; struct s2 { protected: TYPE x, y; }; struct s3 { protected: TYPE x, y; }; struct s4 { protected: TYPE x, y; }; struct X : s1 { operator TYPE() const { return s1::x; } }; struct XX : s2 { operator VECTOR2<TYPE>() const { return VECTOR2<TYPE>(s2::x, s2::x); } }; struct XXX : s3 { operator VECTOR3<TYPE>() const { return VECTOR3<TYPE>(s3::x, s3::x, s3::x); } }; struct XXXX : s4 { operator VECTOR4<TYPE>() const { return VECTOR4<TYPE>(s4::x, s4::x, s4::x, s4::x); } }; public: VECTOR2() {} VECTOR2(const TYPE& x, const TYPE& y) { v.x = x; v.y = y; } X x; XX xx; XXX xxx; XXXX xxxx; // Overload for cout friend ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString) { os << "(" << toString.v.x << ", " << toString.v.y << ")"; return os; } friend ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString); friend ostream& operator<<(ostream& os, const VECTOR4<TYPE>& toString); }; template <typename TYPE> union VECTOR3 { private: struct { TYPE x, y, z; } v; struct s1 { protected: TYPE x, y, z; }; struct s2 { protected: TYPE x, y, z; }; struct s3 { protected: TYPE x, y, z; }; struct s4 { protected: TYPE x, y, z; }; struct X : s1 { operator TYPE() const { return s1::x; } }; struct XX : s2 { operator VECTOR2<TYPE>() const { return VECTOR2<TYPE>(s2::x, s2::x); } }; struct XXX : s3 { operator VECTOR3<TYPE>() const { return VECTOR3<TYPE>(s3::x, s3::x, s3::x); } }; struct XXXX : s4 { operator VECTOR4<TYPE>() const { return VECTOR4<TYPE>(s4::x, s4::x, s4::x, s4::x); } }; public: VECTOR3() {} VECTOR3(const TYPE& x, const TYPE& y, const TYPE& z) { v.x = x; v.y = y; v.z = z; } X x; XX xx; XXX xxx; XXXX xxxx; // Overload for cout friend ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString) { os << "(" << toString.v.x << ", " << toString.v.y << ", " << toString.v.z << ")"; return os; } friend ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString); friend ostream& operator<<(ostream& os, const VECTOR4<TYPE>& toString); }; template <typename TYPE> union VECTOR4 { private: struct { TYPE x, y, z, w; } v; struct s1 { protected: TYPE x, y, z, w; }; struct s2 { protected: TYPE x, y, z, w; }; struct s3 { protected: TYPE x, y, z, w; }; struct s4 { protected: TYPE x, y, z, w; }; struct X : s1 { operator TYPE() const { return s1::x; } }; struct XX : s2 { operator VECTOR2<TYPE>() const { return VECTOR2<TYPE>(s2::x, s2::x); } }; struct XXX : s3 { operator VECTOR3<TYPE>() const { return VECTOR3<TYPE>(s3::x, s3::x, s3::x); } }; struct XXXX : s4 { operator VECTOR4<TYPE>() const { return VECTOR4<TYPE>(s4::x, s4::x, s4::x, s4::x); } }; public: VECTOR4() {} VECTOR4(const TYPE& x, const TYPE& y, const TYPE& z, const TYPE& w) { v.x = x; v.y = y; v.z = z; v.w = w; } X x; XX xx; XXX xxx; XXXX xxxx; // Overload for cout friend ostream& operator<<(ostream& os, const VECTOR4& toString) { os << "(" << toString.v.x << ", " << toString.v.y << ", " << toString.v.z << ", " << toString.v.w << ")"; return os; } friend ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString); friend ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString); }; // Test code int main (int argc, char * const argv[]) { vec2 my2dVector(1, 2); cout << my2dVector.x << endl; cout << my2dVector.xx << endl; cout << my2dVector.xxx << endl; cout << my2dVector.xxxx << endl; vec3 my3dVector(3, 4, 5); cout << my3dVector.x << endl; cout << my3dVector.xx << endl; cout << my3dVector.xxx << endl; cout << my3dVector.xxxx << endl; vec4 my4dVector(6, 7, 8, 9); cout << my4dVector.x << endl; cout << my4dVector.xx << endl; cout << my4dVector.xxx << endl; cout << my4dVector.xxxx << endl; return 0; } The code WORKS and produces the correct output, but I prefer warning free code whenever possible. I followed the advice the compiler gave me (summarized here and described by forums and StackOverflow as the answer to this warning) and added the two things that supposedly tells the compiler what's going on. That is, I added the function definitions as non-friends after the predefinitions of the templated unions: template <typename TYPE> ostream& operator<<(ostream& os, const VECTOR2<TYPE>& toString); template <typename TYPE> ostream& operator<<(ostream& os, const VECTOR3<TYPE>& toString); template <typename TYPE> ostream& operator<<(ostream& os, const VECTOR4<TYPE>& toString); And, to each friend function that causes the issue, I added the <> after the function name, such as for VECTOR2's case: friend ostream& operator<< <> (ostream& os, const VECTOR3<TYPE>& toString); friend ostream& operator<< <> (ostream& os, const VECTOR4<TYPE>& toString); However, doing so leads to errors, such as: LINE 139: error: no match for 'operator<<' in 'std::cout << my2dVector.VECTOR2<float>::xxx' What's going on? Is it something related to how these templated union class-like structures are interrelated, or is it due to the unions themselves? Update After rethinking the issues involved and listening to the various suggestions of Potatoswatter, I found the final solution. Unlike just about every single cout overload example on the internet, I don't need access to the private member information, but can use the public interface to do what I wish. So, I make a non-friend overload functions that are inline for the swizzle parts that call the real friend overload functions. This bypasses the issues the compiler has with templated friend functions. I've added to the latest version of my project. It now works on both versions of GCC I tried with no warnings. The code in question looks like this: template <typename SWIZZLE> inline typename EnableIf< Is2D< typename SWIZZLE::PARENT >, ostream >::type& operator<<(ostream& os, const SWIZZLE& printVector) { os << (typename SWIZZLE::PARENT(printVector)); return os; } template <typename SWIZZLE> inline typename EnableIf< Is3D< typename SWIZZLE::PARENT >, ostream >::type& operator<<(ostream& os, const SWIZZLE& printVector) { os << (typename SWIZZLE::PARENT(printVector)); return os; } template <typename SWIZZLE> inline typename EnableIf< Is4D< typename SWIZZLE::PARENT >, ostream >::type& operator<<(ostream& os, const SWIZZLE& printVector) { os << (typename SWIZZLE::PARENT(printVector)); return os; }

However, apparently it doesn't exist in the repos anymore. Then this post mentioned that gtkglarea solved their problem, as mentioned in this file. Of course that poster neatly forgets to mention exactly what and how gtkglarea solved their problem, and Google is mostly devoid of information on the problem. So I come here asking for help! I would like to install fsv, but it tells me gtk-config doesn't exist. How can I fix this problem in Ubuntu 10.10? Thanks!
