[gnugo-devel] compiling Gnugo

[max-d]

I have tried to reinstall cygwin on my computer
I succeed to make a gnugo3.4 binary which work with Ggo but not with my own
program (even if i put cygwin.dll il the directory).

So i tried to compile with
env CC='gcc -mno-cygwin' ./configure --enable-cosmic-gnugo
 make

but i got that

../utils/libutils.a(getopt.o)(.text+0x673): In function `getopt_internal':
/home/max/gnugo-3.4/utils/getopt.c:668: undefined reference to `_impure_ptr'

Is my cygwin installation not correct or is it a problem which come from the
gnugo package ?
thanks
