wxwidgets program can not link

Post by shelll » Tue Mar 23, 2010 4:38 pm

hi,
thirst thank you for the great IDE, that code lite is.

i have a problem with the latest CL 2.3.0.3833 with mingw 4.4.0 (binary package from sourceforge) on windows xp/7.

after installation my wxWidgets project does not link (i am using an older version of wxwidgets 2.9 from svn, compiled with mingw 4.4.0) with linker error "undefined reference to `WinMain@16'"
so i tried new wxwidgets project from CL's template and i get the same error. here is the complete buildlog

Code: Select all

----------Build Started--------
C:\WINDOWS\system32\cmd.exe /c ""mingw32-make.exe"  -j 2 -f "tesWX_wsp.mk""

older CL 2.2.03681 (with the same mingw and wxwidgets) does not have this problem.

any idea where could be the error? any missing library that i should link or a linker switch?
thank you

Try renaming the file main.c into main.cpp

the file is named main.cpp, there is no main.c.

funny thing is that the very same line e:/data/MinGW-4.4.0/lib//libmingw32.a(main.o):main.c:(.text+0xd2): undefined reference to `WinMain@16' apears in my older wx project and there is no main.c, nor main.cpp.

in the build log i do not even see a compilation of the main.cpp.

Can u post the generated makefiles (tesWX_wsp.mk + tesWX.mk - 2 makefiles)

Did u try to re-build?

Well, it works here.

Do you see that main.cpp is being compiled?

Can you post here the output of the 're-build'?

the rebuild log looks almost the same

the 'clean' part of the rebuild log is deleted after the build starts...

i tried to make a simple console application from template and it does not compile neither. the g++ says "no input file"

Code: Select all

C:\WINDOWS\system32\cmd.exe /c ""mingw32-make.exe"  -j 2 -f "testCon.mk"  all"

attached file is the source, project and make files of the "hello world" console application

Hi Shell,

your console app compiles fine here

Code: Select all

----------Build Started--------
C:\WINDOWS\system32\cmd.exe /c ""mingw32-make.exe"  -j 2 -f "testCon_wsp.mk""
----------Building project:[ testCon - Release ]----------
mingw32-make.exe[1]: Entering directory `G:/tmp/TestCon'
g++ -c  "G:/tmp/TestCon/main.cpp"  -o ./Release/main.o "-IE:/wxWidgets-2.8.10/include" "-IE:/WxWindows/projects_gnu/MyLibs/include"  "-I." "-I." 
g++ -o ./Release/testCon ./Release/main.o  "-LE:/WxWindows/projects_gnu/MyLibs/lib"  "-L."   -O2
mingw32-make.exe[1]: Leaving directory `G:/tmp/TestCon'
----------Build Ended----------
0 errors, 0 warnings
I'm missing the 'g++ -c' line in all your build output, so it looks like only the linker is called, but not the compiler.
Could you show us the generated makefile 'testCon.mk'

Shell,

I posted this yesterday:
eranif wrote:Can u post the generated makefiles (tesWX_wsp.mk + tesWX.mk - 2 makefiles)
If you want help, please post here the generated makefile, since it seems to work on everyones computers but yours.

Looking at the makefile may give us a clue as why is the compile stage is not performed on your machine (like Frank mentioned, there is no 'g++ -c main.cpp ...')
