Apparently the mingw64 website does not provide a 64bit version of msys, so configure will only build a 32bit version. You need to make sure the minw64 compiler (e.g. x86_64-w64-mingw32-gcc.exe) is in the PATH, and pass --host=x86_64-w64-mingw32 to ./configure Just to make sure: do you really need a 64bit version of hwloc for use in a 64bit application, or just hwloc tools which can run on a 64bit windows? (in the latter case a 32bit build should be just fine) > > i am getting this error, when i type make it says. > > "fatal error: sys/mman.h no such file or directory". > > So there's a bug, please post the output of Mmm, maybe you are using rc3? IIRC there was a mingw32 bug there (that's why I didn't provide a windows build of it). I've also tried mingw64 myself, and there's a problem with its definition of LOGICAL_PROCESSOR_RELATIONSHIP which I've just fixed in the svn, so please try tomorrow's nightly snapshot from http://www.open-mpi.org/software/hwloc/nightly/v1.1/ instead.
