Try specifying the type arguments explicitly. Help needed. Thanks

• Locale C++ shared library in /usr/local/lib

  - by Dave

  I'm venturing into the world of C++ and Linux, and am having problems linking against a shared library. I have a library, libicuuc.so.44.1, installed in /usr/local/lib. There is also a link in the same directory, libicuuc.so.44 pointing to that library. My /etc/ld.so.conf reads: include /etc/ld.so.conf.d/*.conf I have a file, /etc/ld.so.conf.d/libc.conf, that contains: # libc default configuration /usr/local/lib However, when I compile my program (that includes LIBS += -licuuc), I get the following error at runtime: error while loading shared libraries: libicuuc.so.44: cannot open shared object file: No such file or directory I am using Qt Creator on Ubuntu 10.04. Any help is greatly appreciated!

• Regular Expression Program

  - by david robers

  Hi I have the following text: SMWABCCA ABCCAEZZRHM NABCCAYJG XABCCA ABCCADK ABCCASKIYRH ABCCAKY PQABCCAK ABCCAKQ This method takes a regex in out by the user and SHOULD print out the Strings it applies to but seems to print out something completely different: private void matchIt(String regex) { Pattern p = Pattern.compile(regex); Matcher m = null; boolean found = false; for(int i = 0; i < data.length; i++){ m = p.matcher(data[i]); if(m.find()){ out.println(data[i]); found = true; } } if(!found){ out.println("Pattern Not Found"); } } When inputting "[C]" It outputs: SMWABCCA ABCCAEZZRHM NABCCAYJG XABCCA ABCCADK ABCCASKIYRH ABCCAKY PQABCCAK ABCCAKQ Any ideas why? I think I'm using m.find() improperly...

• What is your favorite new feature in php 5.3?

  - by Kris

  I'm trying to compile a list of new features found in php 5.3. that I have to check out as time permits. I'd like to do this in the order of usefulness of the features. The question is subjective, that is the point. I want to end up with a list ordered by what the community likes. Such a list would hopefully be useful to many and the I have not been able to find one on SO. Please name one specific feature per answer, thanks in advance! What is your favorite new feature in php 5.3?

• Is it possible in Scala to force the caller to specify a type parameter for a polymorphic method ?

  - by Alex Kravets

  //API class Node class Person extends Node object Finder { def find[T <: Node](name: String): T = doFind(name).asInstanceOf[T] } //Call site (correct) val person = find[Person]("joe") //Call site (dies with a ClassCast inside b/c inferred type is Nothing) val person = find("joe") In the code above the client site "forgot" to specify the type parameter, as the API writer I want that to mean "just return Node". Is there any way to define a generic method (not a class) to achieve this (or equivalent). Note: using a manifest inside the implementation to do the cast if (manifest != scala.reflect.Manifest.Nothing) won't compile ... I have a nagging feeling that some Scala Wizard knows how to use Predef.<:< for this :-) Ideas ?

• Why isn't the compiler smarter in this const function overloading problem?

  - by Frank

  The following code does not compile: #include <iostream> class Foo { std::string s; public: const std::string& GetString() const { return s; } std::string* GetString() { return &s; } }; int main(int argc, char** argv){ Foo foo; const std::string& s = foo.GetString(); // error return 0; } I get the following error: const1.cc:11: error: invalid initialization of reference of type 'const std::string&' from expression of type 'std::string* It does make some sense because foo is not of type const Foo, but just Foo, so the compiler wants to use the non-const function. But still, why can't it recognize that I want to call the const GetString function, by looking at the (type of) variable I assign it to? I found this kind of surprising.

• What's the difference between => , ()=>, and Unit=>

  - by Malvolio

  I'm trying to represent a function that takes no arguments and returns no value (I'm simulating the setTimeout function in JavaScript, if you must know.) case class Scheduled(time : Int, callback : => Unit) doesn't compile, saying " `val' parameters may not be call-by-name" case class Scheduled(time : Int, callback : () => Unit) compiles, but has to be invoked strangely, instead of Scheduled(40, { println("x") } ) I have to do this Scheduled(40, { () => println("x") } ) What also works is class Scheduled(time : Int, callback : Unit => Unit) but is invoked in an even-less-sensible way Scheduled(40, { x : Unit => println("x") } ) (What would a variable of type Unit be?) What I want of course is a constructor that can be invoke the way I would invoke it if it were an ordinary function: Scheduled(40, println("x") ) Give baby his bottle!

• template specilization using member enums

  - by Altan

  struct Bar { enum { Special = 4 }; }; template<class T, int K> struct Foo {}; template<class T> struct Foo<T::Special> {}; Usage: Foo<Bar> aa; fails to compile using gcc 4.1.2 It complains about the usage of T::Special for partial specilization of Foo. If Special was a class the solution would be to a typename in front of it. Is there something equivalent to it for enums (or integers)? Thanks, Altan

• Maven + Tomcat acceleration

  - by Bar

  I am writing a web application with Maven in the Eclipse IDE, and use Tomcat servlet container. So, I run Maven like this: mvn clean compile. It is reasonable that after this oepration I must re-run Tomcat so it can reinitialize the context (Sysdeo Tomcat launcher helps a lot). The problem is Maven execution and subsequebt Tomcat re-running takes noticable amount of time (like 10+ seconds for Maven and 20+ sec. for Tomcat, because of logging, Hibernate mappings, etc.) every time I do it. Is there any automated and more faster solution for these two operatioins? As I see it, a way better solution can be moving re-compiled classes only to the target dir.

• undefined reference to "func" when complied with GCC

  - by hotlemontea

  I implement a link list in two files in linklist.h and linklist.c, and I call some functions defined in linklist.h in main function of main.c. linklist.h is included in both linklist.c and main.c. When I compile this program by GCC with Makefile, the error named "undefined reference to xxx" occurs. I think my Makefile is written correctly as below. So what is the possible reason for this linking error CC=gcc CFLAGS= -g -O2 TARGET=target OBJECTS=main.o linklist.o TARGET: $(OBJECTS) $(CC) $(CFLAGS) $(OBJECTS) -o $(TARGET) clean: rm target $(OBJECTS) main.o:linklist.h linklist.o:linklist.h

• Is it a good idea to include a large text variable in compiled code?

  - by gladman

  I am writing a program that produces a formatted file for the user, but it's not only producing the formatted file, it does more. I want to distribute a single binary to the end user and when the user runs the program, it will generate the xml file for the user with appropriate data. In order to achieve this, I want to give the file contents to a char array variable that is compiled in code. When the user runs the program, I will write out the char file to generate an xml file for the user. char* buffers = "a xml format file contents, \ this represent many block text \ from a file,..."; I have two questions. Q1. Do you have any other ideas for how to compile my file contents into binary, i.e, distribute as one binary file. Q2. Is this even a good idea as I described above?

• c++ compilation error

  - by clamp

  hello, i got a compile error which i do not understand. i have a h/cpp file combination that does not contain a class but just defines some utility functions. when i try to use a struct that is defined in another class i get the error: error C2027: use of undefined type so, stripped down to the problem, the h file looks like this namespace A { void foo(B::C::SStruct const & Var); } the definition of SStruct is in a class which is in another h-file, that is of course included. namespace B { Class C { struct SStruct { }; } } what am i missing here? thanks!

• how to step into code from jars (non JDK) using IntelliJ?

  - by ascari

  I am new to IntelliJ (and Stackoverflow) and fairly new to Java,In my application I am using code from jars that in IntelliJ I added as "External Libraries". I also have the source code for those jars, but I rather not compile it (they are huge and complex). Now while debugging my application I would like to step into the library code that is compiled into those jars. How can I set up IntelliJ to do that? Is there another way other that attaching the entire jar library source code to my application code?

• C/C++ enums: Detect when multiple items map to same value

  - by Dan

  Is there a compile-time way to detect / prevent duplicate values within a C/C++ enumeration? The catch is that there are multiple items which are initialized to explicit values. Background: I've inherited some C code such as the following: #define BASE1_VAL (5) #define BASE2_VAL (7) typedef enum { MsgFoo1A = BASE1_VAL, // 5 MsgFoo1B, // 6 MsgFoo1C, // 7 MsgFoo1D, // 8 MsgFoo1E, // 9 MsgFoo2A = BASE2_VAL, // Uh oh! 7 again... MsgFoo2B // Uh oh! 8 again... } FOO; The problem is that as the code grows & as developers add more messages to the MsgFoo1x group, eventually it overruns BASE2_VAL. This code will eventually be migrated to C++, so if there is a C++-only solution (template magic?), that's OK -- but a solution that works with C and C++ is better.

• Passing Session[] and Request[] to Methods in C#

  - by NYARROW

  In C#, How do you pass the Session[] and Request[] objects to a method? I would like to use a method to parse out Session and Request paramaters for a .aspx page to reduce the size of my Page_Load method. I am passing quite a few variables, and need to support both POSTand GET methods. For most calls, not all variables are present, so I have to test every variable multiple ways, and the code gets long... This is what I am trying to do, but I can't seem to properly identify the Session and Request paramaters (this code will not compile, because the arrays are indexed by number) static string getParam( System.Web.SessionState.HttpSessionState[] Session, System.Web.HttpRequest[] Request, string id) { string rslt = ""; try { rslt = Session[id].ToString(); } catch { try { rslt = Request[id].ToString(); } catch { } } return rslt; } From Page_Load, I want to call this method as follows to retrieve the "MODE" paramater: string rslt; rslt = getParam(Session, Request, "MODE"); Thanks!

What's wrong? Thank you.

• How do you extend python with C++?

  - by superjoe30

  I've successfully extended python with C, thanks to this handy skeleton module. But I can't find one for C++, and I have circular dependency trouble when trying to fix the errors that C++ gives when I compile this skeleton module. How do you extend Python with C++? I'd rather not depend on Boost (or SWIP or other libraries) if I don't have to. Dependencies are a pain in the butt. Best case scenario, I find a skeleton file that already compiles with C++.

• problem using keil uvision 3

  - by Blossom

  I am trying to compile a C code using Keil uvision 3. The entire code gets compiled only if I use large memory model by choosing option xdata for target. To use this model I have to use external data RAM which is not possible for me due to some reasons. So I decided to go with pdata option. Can anybody please help me with the exact steps to be carried out for using pdata? I am using 89V51RD2. I am much confused with the options like BL51 MISC, BL51 Locate etc.

• C++ runtime, display exception message

  - by aaa

  hello. I am using gcc on linux to compile C++ code. There are some exceptions which should not be handled and should close program. However, I would like to be able to display exception string: For example: throw std::runtime_error(" message"); does not display message, only type of error. I would like to display messages as well. Is there way to do it? it is a library, I really do not want to put catch statements and let library user decide. However, right now library user is fortran, which does not allow to handle exceptions. in principle, I can put handlers in wrapper code, but rather not to if there is a way around Thanks

• Embarassing C++ question regarding const

  - by Neil Butterworth

  My comments on this answer got me thinking about the issues of constness and sorting. I played around a bit and reduced my issues to the fact that this code: #include <vector> int main() { std::vector <const int> v; } will not compile - you can't create a vector of const ints. I suppose I should have known this, but I've never needed to create such a thing before. However, it seems like a useful construct to me, and I wonder if there is any way round this problem - I want to add things to a vector (or whatever), but they should not be changed once added. There's probably some embarrassingly simple solution to this, but it's something I'd never considered before.

• Any way to make GetTypes() less brittle.

  - by scope-creep

  I'm iterating through all the types in GAC, GAC_32 and GAC_MSIL looking for specific types, fundamentally to match those using clauses in my source code, so when I compile the source. I'll know exactly what assembly dll's to provide. I'm getting all the file names from each of those directory and applying GetTypes to each assembly in turn and comparing the returned types against my using list. But the problem I have is that GetTypes() keeps crapping out with an exception, when it can't load the types from a loaded assembly. Is their any way to make GetTypes() less brittle. For instance, when parsing this assembly on my box, {blbmmc, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35}, it craps out. Any suggestions welcome. I know this is a fairly lengthly process, but I figure i'll eventually use a subset of common assemblies to search, or possibly cache the list of types-assembly dll name at program start. Thanks.

• ordering a collection by an association's property

  - by neiled

  class Person belongs_to :team class Status #has last_updated property class Team has_many :members, :class => "Person" Ok, so I have a Team class which has many People in it and each of those people has a status and each status has a last_updated property. I'm currently rendering a partial with a collection similar to: =render :partial => "user", :collection => current_user.team.members Now how do I go about sorting the collection by the last_updated property of the Status class? Thanks in advance! p.s. I've just written the ruby code from memory, it's just an example, it's not meant to compile but I hope you get the idea!
