Hi Osvalds,
I emailed the Charm++ developers about your issue. Their response:
This is an issue in hwloc, which for some reason here is trying to use the POSIX sysconf function. This is likely due to a misconfiguration in the build environment or something like that, hwloc's configure should pick the right thing to use here. To note, sysconf should be usable with Cygwin on Windows, but not with native Windows or MinGW builds.
Hope this helps,
Dave
