Undefined reference to WinMain in Cygwin

cygwin, winmain

Solution

Use `-c` compile flag to only produce object file. Without `-c` it tries to link an executable and the linker (called automatically) fails.

Problem

I am trying to compile and having following problem ``` $ gcc errlib.c -o errlib.o /usr/lib/gcc/x86_64-pc-cygwin/4.8.2/../../../../lib/libcygwin.a(libcmain.o): In function `main': /usr/src/debug/cygwin-1.7.30-1/winsup/cygwin/lib/libcmain.c:39: undefined reference to `WinMain' /usr/src/debug/cygwin-1.7.30-1/winsup/cygwin/lib/libcmain.c:39:(.text.startup+0x7e): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `WinMain' collect2: error: ld returned 1 exit status ``` Any suggestions? These files are well tested and generated the code fine before but now i think there might be some cygwin settings or so ... m compiling on windows 8 on cygwin.
