Hi Eric, Some time ago I filed https://bugzilla.redhat.com/show_bug.cgi?id=969231 against the Fedora mingw-libvirt package for this issue. According to Daniel Berrange winpthreads isn't following the POSIX specifications as the symbol pthread_sigmask should be mentioned in signal.h while for winpthreads this symbol is currently only mentioned in pthread.h. Setting up an environment with Fedora MinGW + winpthreads requires some preparation (as I don't want to pollute rawhide yet). A recent rawhide environment should be enough as starting point. I just created some scratch builds which you can install directly with 'yum localinstall' to have a winpthreads-based mingw environment: http://koji.fedoraproject.org/koji/taskinfo?taskID=5871269 http://koji.fedoraproject.org/koji/taskinfo?taskID=5871279 Regards, Erik -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
