[Bf-committers] "multiple definition of _main" error when trying to link blenderplayer (Blender 2.5 - Makefiles)

Fri Jul 31 03:49:13 CEST 2009

 Hello.

I'm having some trouble compiling Blender 2.5 with the Makefiles on Cygwin/MinGW. I'm using SVN revision 21487. I've managed to get past a number of linker errors by adding

missing libs to the linker line and running it manually from the command line. I'm having trouble with one error while trying to link the blenderplayer, and I need some help. The

error is as follows-

/cygdrive/c/build25/blender/obj/windows/creator/libcreator.a(creator.o):creator.c:(.text+0x470): multiple definition of `_main'

/cygdrive/c/build25/blender/obj/windows/gameengine/GamePlayer/ghost/libghost.a(GPG_ghost.o):GPG_ghost.cpp:(.text+0x300): first defined here

collect2: ld returned 1 exit status

Both of these files had "main" functions in them in Blender 2.48, and I don't remember it causing a linker error.

Below is the linker line I'm using. I apologize if it makes for long horizontal scrolling, it's all one line.

There may still be a problem with the linker line, I don't know.

Thanks in advance for assistance.
