[This is just a FYI ...] Upstream binutils or gcc changed the default way that symbols are exported for cross-compiled (Fedora MinGW) DLLs. Previously all symbols were exported. Now they are only exported if they are explicitly listed in a *.def file. There are two ways that libvirt could be changed to do the right thing here. Either (probably simplest) add '-export-all-symbols' to the libtool command line. This would have to be done conditionally based on Win32 being the compilation target. Or create a *.def file. It looks like: LIBRARY libvirt.dll DESCRIPTION "libvirt foo blah" EXPORTS <<list of symbol names, one per line>> http://msdn.microsoft.com/en-us/library/d91k01sh%28VS.80%29.aspx http://msdn.microsoft.com/en-us/library/28d6s79h%28VS.80%29.aspx The LIBRARY and DESCRIPTION lines are optional. You have to add '-export-symbols libvirt.def' to the libtool command line. (It's not clear to me at the moment if you only do this for Windows or if it's safe to pass this on all platforms -- the documentation for this is very sparse). There is a third method: you can munge all the code by adding __declspec(dllexport) to all exported symbols in the header files, conditionally of course. I'm pretty sure that's the worst of all worlds. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-top is 'top' for virtual machines.
