Hi, 2015-12-09 20:53 GMT+01:00 Eric Blake <eblake AT redhat DOT com>: > That's because <direct.h> is an old, non-standard header not present on > modern POSIX-y machines.

I modified GDAL lib dependency to include dirent.h instead of direct.h. The configure doesn't fails, good. Unfortunately several compiled GRASS tools fails to run when building: 1 [main] g.proj (2604) C:\cygwin64\home\landa\grass_trunk\dist.x86_64-w64-mingw32\bin\g.proj.exe: *** fatal error - cygheap base mismatch detected - 0x180321400/0x901400. This problem is probably due to using incompatible versions of the cygwin DLL. Search for cygwin1.dll using the Windows Start->Find/Search facility and delete all but the most recent version. The most recent version *should* reside in x:\cygwin\bin, where 'x' is the drive on which you have installed the cygwin distribution. Rebooting is also suggested if you are unable to find another cygwin DLL. I do not have any other cygwin1.dll in path. Other GRASS tools are compiled successfully, so the issue is probably related to linked libraries or? > That depends on whether your code is POSIX-y and targetting cygwin, or > is tied to Windows APIs and should be targetting mingw. > >> >> I am also not sure what will be difference between binaries compiled >> using cygwin and mingw32-w64 toolchain except of dependencies (like >> cygwin1.dll).

OK, thanks for explanation!
