Hi I've tried this combination MSYS installed c:\msys mingw installed c:\mingw
and as long as I specified the full path to configure it worked fine , ie ./configure CC=/c/mingw/bin/x86_64-w64-mingw32-gcc.exe .... although for C++ you would also have to tell it where the standard C++ library is , which I assume is something like LD=.... The only time I have trouble is when there are spaces in any of the paths. The only other issue for me is that try.exe , speed.exe tuneup.exe wont build , this is due to the makefile not having any include paths , dont know why this only affects mingw64 Jason -- You received this message because you are subscribed to the Google Groups "mpir-devel" group.
