wxwidgets program can not link

[shelll]

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

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

Eran

[shelll]

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.

[eranif]

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

Did u try to re-build?
Eran

[shelll]

rebuild does not help. here is the whole project with source code and makefiles

[eranif]

Well, it works here.

Do you see that main.cpp is being compiled?

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

[shelll]

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"

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

Hi Shell,

your console app compiles fine here

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:

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 ...')

[shelll]

all generated make files are included in those zip archives...

here is the testCon.mk
