Building on cygwin 64: undefined reference to `WinMain'

This is after a fresh rebuilt of ATS1 and ATS2:

make -C utils/atscc -f Makefile all

My only clue so far is that none of the *.c files being compiled seem to
include a main entry point, and this may be confusing cygwin’s linker.

Sorry for the delayed reply; I started looking at it again and you are
correct. In fact, the file I had peaked at previously (atscc_main_dats.c ) was
the only one that had any code in it. The others ( atscc_print_dats.c,
patscc_dats.c ) are empty.On Sunday, September 21, 2014 12:18:36 AM UTC-4, gmhwxi wrote:

I suspect that patscc_dats.c was not properly generated (which might be
empty).

I’m actually getting this behavior on Linux as well. I’ll look in to it a
bit more and submit an issue on github.On Friday, September 26, 2014 2:17:48 PM UTC-4, Brandon Barker wrote:
