OpenCOBOL, MINGW/Cygwin and gmp.h problem



Hi all,

I'm new into OC and have some beginner level in Linux.

I successfully built GMP and Libtool. Now when I try to ./configure
OpenCOBOL it stops after

checking for string.h... yes
checking for memory.h... yes
checking for strings.h... yes
checking for inttypes.h... yes
checking for stdint.h... yes
checking for unistd.h... yes
checking for dbopen... no
checking gmp.h usability... no
checking gmp.h presence... no
checking for gmp.h... no
configure: error: gmp.h is required

I tried to put this gmp.h in every possible directory. Doesn't help.

Any ideas?

Thank you.
