Reg: Compiling Problems

[mickey22]

Hi all,

I am trying to compile a VC++ project and it is win32 console application.Whe n I try to compile it I get a lot of linking problems.I have included all the header files needed for the project..I have no idea of how to solve them as I am little bit new to vc++..Could anyone advice or tell me whats wrong in my program..Here are some of my errors:

(1) error LNK2019: unresolved external symbol "public: __thiscall Parser::Parser( class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,unsigned short,unsigned short,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >,class std::basic_stri ng<char,struct std::char_trait s<char>,class std::allocator< char> >)" (??0Parser@@QAE @V?$basic_strin g@DU?$char_trai ts@D@std@@V?$al locator@D@2@@st d@@0000GG00000@ Z) referenced in function _main homogenity.obj

Thanks a lot in advance.

Can you post the relevant section of code where this error came from?

Hi Sicarie,

Thank you for quick reply..parser.h is the header file already written by somebody...I am thinking its not able to link parser.h file..I am not sure abt it..Any kind of suggestions or help would be great.Thanks.

Here's my code:

#include "stdafx.h"
#include "parser.h"

//int _tmain(int argc, _TCHAR* argv[])
//validate function

int main(int argc, char **argv)  //new added
{

	Parser *cpar=NULL;
                                                         
	     cpar=new Parser("homogenity",
                     "calculate roi",
                     "2007",
                     "e n u is w algo oi ",
	     "(e$ n$ u$ [is]$ w$ [algo]$ [oi]$)", iterations,subsets, "","","","","");

	 if (argc == 1) { cpar->usage(false);            
                      delete cpar;
                      cpar=NULL;
                      GM::close();
                      return(EXIT_SUCCESS);
                    }
     if (!cpar->parse(argc, argv))              
      { delete cpar;
        cpar=NULL;
        GM::close();
        return(-1);
      }
    	return 0;
}

[horace1]

you are including parser.h at compile time - is there another file parser.cpp (or parser.o or parser.obj) which contains the implementation code of Parser. This would be linked with your code and hopefully the link time errors should go away.

[mickey22]

Horace1,

Thank you for the suggestion and I will try to do that.Could you please tell me how u link .cpp file to a vc++ project and should I just build my project as usual or should I have to compile all source files included in my project separately ??Thanks.

[mickey22]

Hi Horace1,

I just wanted to inform you that I have tried to add the .cpp file to my project and also added the header file and it remove my linking errors.Thank you for the solution..But I have been arised with the problem that there existes no stdafx.h in the parser.cpp file I added recently..When I checked in this .cpp file I did not find it..Its giving me fatal error C1010. stdafx.h and .cpp both are included in my actual source project.Thats not a problem, prob is with newly added source file which is read only..

Can you please help me with this..Thanks a lot once again for helping me out.

I don't use vc++ so no idea what is going on - perhaps we have vc++ experts who can assit? You say that parser.cpp is read only - can you change it to full access - if using windows right button click the file in Windows Explorer, click properties and clear the Read Only button.

[mickey22]

It can be done in that way but I am supposed to use it as it is without making any changes ..I have used Use precompiled header option in the project properties but still gives me the error..

Anyway thank you horace1 for your prompt replies and for your help..

I would appreciate if anyone in the group can help me in this issue.I am stuck at this point.Thanks in advance.

Hi all,

I am getting the error LNK:c1010...It says that stdafx.h is not in the source file...Actually I have added a .cpp file to my project which cannot be changed at all as it is defined by somebody and so I cannot include stdafx.h file in it.

But I have included it already in my original .cpp file and have its project properties set to use precompiled header files option so that it could be used to other source files added to my project..I am not sure if I need to change any settings..

Still I am getting the same errror when I build my project..Can anyone please help me how to solve this..I am really stuck at this point..Thank you very much..Look forward to hear from you soon.
