• Makefile automatic link dependency ?

  - by Kuang Chen

  It's easy to let program figure out the dependency at compile time, (with gcc -MM). Nevertheless, link dependency (deciding which libraries should be linked to) seems to be difficult to figure out. This issue become emergent when multiple targets with individual libraries to link to are needed. For instance, three dynamic library targets t1.so, t2.so and t3.so needs to be built. t1.so needs math library (-lm), while t2 and t3 don't. It would be tedious to write separate rules. A single rule requiring the three targets linked with math library saves the trouble. However, it causes inflation of target size since math library is unused for t2.so and t3.so. Any ideas?

• Not a statement?

  - by abelenky

  I have a simple little code fragment that is frustrating me: HashSet<long> groupUIDs = new HashSet<long>(); groupUIDs.Add(uid)? unique++ : dupes++; At compile time, it generates the error: Only assignment, call, increment, decrement, and new object expressions can be used as a statement HashSet.Add is documented to return a bool, so the ternary (?) operator should work, and this looks like a completely legitimate way to track the number of unique and duplicate items I add to a hash-set. When I reformat it as a if-then-else, it works fine. Can anyone explain the error, and if there is a way to do this as a simple ternary operator?

• To use package properly, how to arrange directory, file name, unit test file?

  - by Stephen Hsu

  My source files tree is like this: /src /pkg /foo foo.go foo_test.go Inside foo.go: package foo func bar(n int) { ... } inside foo_test.go: package foo func testBar(t *testing.T) { bar(10) ... } My questions are: Does package name relates to directory name, source file name? If there is only one source file for a package, need I put it in a directory? Should I put foo.go and foo_test.go in the same package? In the foo_test.go, as it's in the same package as foo.go, I didn't import foo. But when I compile foo_test.go with 6g, it says bar() is undefined. What should I do?

• Nested for_each with lambda not possible?

  - by Ela782

  The following code does not compile in VS2012, it gives error C2064: term does not evaluate to a function taking 1 arguments on the line of the second for_each (line 4 below). vector<string> v1; for_each(begin(v1), end(v1), [](string s1) { vector<string> v2; for_each(begin(v2), end(v2), [](string s2) { cout << "..."; }); }); I found some related stuff like http://connect.microsoft.com/VisualStudio/feedback/details/560907/capturing-variables-in-nested-lambdas which shows a bug (they are doing something different) but on the other hand that shows that what I print above should be possible. What's wrong with the above code?

• How to call operator<< on "this" in a descendant of std::stringstream?

  - by romkyns

  class mystream : public std::stringstream { public: void write_something() { this << "something"; } }; This results in the following two compile errors on VC++10: error C2297: '<<' : illegal, right operand has type 'const char [10]' error C2296: '<<' : illegal, left operand has type 'mystream *const ' Judging from the second one, this is because what this points at can't be changed, but the << operator does (or at least is declared as if it does). Correct? Is there some other way I can still use the << and >> operators on this?

• Question about C Pointers (just learning)

  - by Mike

  I am curious as to why this is an error and what the error message means. Here is some code. int *x[] = {"foo", "bar", "baz"}; int *y[] = {"foo", "bar", "baz"}; x = y; I try to compile and I get this: error: incompatible types when assigning to type ‘char [3]’ from type ‘char *’ Question #1 why is this an error? and Question #2 why are the types different? Thanks for you help.

• Compiler error while compiling the RAPID library on VS2008

  - by Demi

  I've downloaded the RAPID library and tried to compile it on Microsoft Visual Studio 2008. However, I'm getting the following compiler error: C4430 missing type specifier - int assumed. Note: C++ does not support default-int at this code segment (the exact line that produces the error is int flag): class RAPID_model { public: box *b; int num_boxes_alloced; tri *tris; int num_tris; int num_tris_alloced; int build_state; int build_hierarchy(); friend RAPID_Collide(double R1[3][3], double T1[3], double s1, RAPID_model *RAPID_model1, double R2[3][3], double T2[3], double s2, RAPID_model *RAPID_model2, int flag); Can anyone please help me with this? Thank you

• VBScript Writing to Server Text File

  - by Keyfer Mathewson

  I have created a VBScript which pulls the service tag, username, and computer name from a computer. What I need to do now is compile this information in a text document. How it's set up is as follows: We have an Active Directory Server, with a folder for login scripts. I have created a batch file to run this .vbs script, and the script works well so far. What I now need is for a file on the AD server, called "logging.txt", to be populated with the information that is created with the .vbs script. This is the script I have so far: 'Get Dell Service Tag Info set ProSet = GetObject("winmgmts:").InstancesOf("Win32_BIOS") Set ProSet1 = GetObject("winmgmts:").InstancesOf("Win32_SystemEnclosure") For each Pro in ProSet For each Pro1 in ProSet1 ServiceTag=Pro.SerialNumber wscript.echo ServiceTag exit for Next exit for Next 'get username and computername, could also be asked in a batch Set oShell = WScript.CreateObject("WScript.Shell") Set oShellEnv = oShell.Environment("Process") sComputerName = oShellEnv("ComputerName") sUsername = oShellEnv("username") wscript.echo sComputerName & " " & sUsername Thank you very much in advance!

• Can I use MFC objects in STL containers?

  - by Jesse Stimpson

  The following code doesn't compile for me in MSVC2005: std::vector<CMenu> vec(10); CMenu is an MFC menu object (such as a context menu). Through some testing I learned that CMenu does not have a public copy constructor. To do what I wanted to do, I needed to use a dynamic array. CMenu* menus = new CMenu[10]; // ... delete [] menus; Of course, now I've lost all the benefits of using an STL container. Do I have any other options?

• Is the "==" operator required to be defined to use std::find

  - by user144182

  Let's say I have: class myClass std::list<myClass> myList where myClass does not define the == operator and only consists of public fields. In both VS2010 and VS2005 the following does not compile: myClass myClassVal = myList.front(); std::find( myList.begin(), myList.end(), myClassVal ) complaining about lack of == operator. I naively assumed it would do a value comparison of the myClass object's public members, but I am almost positive this is not correct. I assume if I define a == operator or perhaps use a functor instead, it will solve the problem. Alternatively, if my list was holding pointers instead of values, the comparison would work. Is this right or should I be doing something else?

• Static initialization of a struct with class members

  - by JS Bangs

  I have a struct that's defined with a large number of vanilla char* pointers, but also an object member. When I try to statically initialize such a struct, I get a compiler error. typedef struct { const char* pszA; // ... snip ... const char* pszZ; SomeObject obj; } example_struct; // I only want to assign the first few members, the rest should be default example_struct ex = { "a", "b" }; SomeObject has a public default constructor with no arguments, so I didn't think this would be a problem. But when I try to compile this (using VS), I get the following error: error C2248: 'SomeObject::SomeObject' : cannot access private member declared in class 'SomeObject' Any idea why?

• Problem compiling mod_wsgi for python2.6 on Cent OS 5.3

  - by webdev

  I am running a website on CentOS 5.3. I understand centos will break if the default python 2.4 is upgraded. I followed this site (http://www.question-defense.com/2009/12/25/how-to-install-python-2-6-on-centos-5-without-breaking-yum) and got python 2.6 installed. Now if I run "python" it runs python2.4 and if I run "python26" it runs python2.6. I am trying to compile mod_wsgi-3.2. When it run ./configure it takes only python 2.4 environment. I have tried using the --with-python=/usr/bin/python26. That way, "make" command does not work. Can someone throw some light on this? Thanks in advance

• Select n+1 problem

  - by Arnis L.

  Foo has Title. Bar references Foo. I have a collection with Bars. I need a collection with Foo.Title. If i have 10 bars in collection, i'll call db 10 times. bars.Select(x=x.Foo.Title) At the moment this (using NHibernate Linq and i don't want to drop it) retrieves Bar collection. var q = from b in Session.Linq<Bar>() where ... select b; I read what Ayende says about this. Another related question. A bit of documentation. And another related blog post. Maybe this can help? What about this? Maybe MultiQuery is what i need? :/ But i still can't 'compile' this in proper solution. How to avoid select n+1?

• So I dynamically load a jar at runtime how do I use it?

  - by justinhj

  So question 194698 shows how to load a jar file at runtime and you can load individual named classes and get a Class object. Now my problem is I want to be able to cast those Classes to the types they really are, but I can't because I can't use an import since the whole point is to load it at runtime rather than compile time. It seems like the way to go is to use reflection to discover the functions and field names, but that seems brittle since the API in the jar files could change and the code won't break until it is run. Is there a better way?

• Marvell C++ compiler (for Windows CE) for building Qt

  - by vnm

  Hello, I was able to build Qt 4.5 for Windows CE (ARM4VI) using MS VisualC++ compiler. Now, I am trying to compile Qt 4.5 for Windows CE 5.0 using Marvel C++ compiler v 2.2 (former Intel C++ compiler for XScale architecture) for achieving some performance benefit. It seems, that this compiler not officially supported for building Qt by trolltech (no appropriate mkspec in mkspec's folder of Qt folder). So, my questions: Is it worth to trying build Qt by this compiler for achieving performance enhancement ? Is there any way for building Qt using Marvell C++ compiler (by creating my own mkspec or something like that)?

• What workflow should I use for JavaScript editing?

  - by Patrick

  Warning: I have very little JavsScript experience. In my past programming experience, I usually have a standalone interpreter/compiler, a text editor and a command line to compile/run my software or my tests (I love test driven development). I really like it this way, since I have the feeling of being in complete control over the tools. However, editing JavaScript I need to put statements in a text file , open my web browser and click on reload. I don't feel comfortable with it, as I cannot really see what is going on (besides some alert boxes). Can you suggest me (I'm on a Mac) another workflow? Perhaps with a debugger? Is there a standalone JavaScript interpreter?

• Need help on how to setup package structure and project

  - by jax

  I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)

• accessing variable sheet ranges within Google spreadsheet?

  - by Daniel Harvey

  I've been trying to keep this little project entirely within Google docs, but I may have hit a wall. The spreadsheet is being used as a way for multiple users to record individual events with a Template they duplicate. I want to be able to compile a list of names of those attended onto a "report" sheet from all of the unique sheets, which should be after a certain sheet index [3] to [infinite]. Is this sort of variable sheet range possible in Google spreadsheets or do I need to go to the API to get this accomplished?

• C input loop for shell

  - by AustinM

  So I'm working on creating a very simple C program that just preforms shell commands. This is what I have so far: #include <stdio.h> int main() { char input[30]; fputs("$ ", stdout); fflush(stdout); fgets(input, sizeof input, stdin); system(input); } It works, but only for one command. For example if I compile and type ./cmd I get the $ prompt. If I type ls I get what I'm supposed to get. But then it exits and goes back to the regular system shell. How can I make it so after the user types a command it goes back to the "$" input.

• different behavior when using re.finditer and re.match.

  Hi, I'm working on a regex to to collect some values from a page through some script. I'm using re.match in condition but it returns false but if i use finditer it returns true and body of condition is executed. i tested that regex in my own built tester and it's working there but not in script. here is sample script. result = [] RE_Add0 = re.compile("\d{5}(?:(?:-| |)\d{4})?", re.IGNORECASE) each = ''Expiration Date:\n05/31/1996\nBusiness Address: 23901 CALABASAS ROAD #2000 CALABASAS, CA 91302\n' if RE_Add0.match(each): result0 = RE_Add0.match(each).group(0) print result0 if len(result0) < 100: result.append(result0) else: print 'Address ignore' else: None

• How to print size_t variable portably?

  - by ArunSaha

  I have a variable of type size_t, and I want to print it using printf(). What format specifier do I use to print it portably? In 32-bit machine, %u seems right. I compiled with g++ -g -W -Wall -Werror -ansi -pedantic, and there was no warning. But when I compile that code in 64-bit machine, it produces warning. size_t x = <something>; printf( "size = %u\n", x ); warning: format '%u' expects type 'unsigned int', but argument 2 has type 'long unsigned int' The warning goes away, as expected, if I change that to %lu. The question is, how can I write the code, so that it compiles warning free on both 32- and 64- bit machines? Edit: I guess one answer might be to "cast" the variable into an unsigned long, and print using %lu. That would work in both cases. I am looking if there is any other idea. (C, C++)

• Java splitting string by custom regex match

  - by slikz

  I am completely new to regular expressions so I'm looking for a bit of help here. I am compiling under JDK 1.5 Take this line as an example that I read from standard input: ab:Some string po:bubblegum What I would like to do is split by the two characters and colon. That is, once the line is split and put into a string array, these should be the terms: ab:Some string po:bubblegum I have this regex right now: String[] split = input.split("[..:]"); This splits at the semicolon; what I would like is for it to match two characters and a semicolon, but split at the space before that starts. Is this even possible? Here is the output from the string array: ab Some String po bubblegum I've read about Pattern.compile() as well. Is this something I should be considering?
