2010/8/12 Gal Gafni <gal(a)csl-int.com&gt;: Even without your XDR problem libvirt 0.8.3 won't compile successfully on Windows, you'll at least need this additional patch: http://libvirt.org/git/?p=libvirt.git;a=commit;h=177e17e4626e18c1ce80f852... So you either apply this patch manually on top of the libvirt 0.8.3 tarball (this will require autotools available, because the patch touches configure.ac), or you build from the hourly git snapshot: http://libvirt.org/sources/libvirt-git-snapshot.tar.gz I'm not sure where you got xdr-4.0-mingw2 from. I use the portablexdr lib http://people.redhat.com/~rjones/portablexdr/files/portablexdr-4.9.1.tar.gz You also might need to run configure with additional envvars set in order to have it pick up the libs correctly CFLAGS=-I/include LDFLAGS=-L/lib ./configure Because MSYS (I assume you use MSYS) uses /include and /lib instead of /usr/include and /usr/lib. Non I'm aware of. A while ago I created a bunch of scripts that setup an MSYS/MinGW environment on Windows, download and/or compile all dependencies and finally compile libvirt. You can find this scripts on github: http://github.com/photron/msys_setup Currently the scripts build libvirt 0.8.1, they are a bit outdated by now. I'll probably update them soon. Matthias
