[libvirt] Re: libvirt on mingw: undefined reference to htonl/ntohl

[Brecht Sanders]

Hello again,
I may have been a bit to fast quick with my mail.
Now I was able to compile and link libvirt-0.4.3 (except for the tests 
which depend on fork e.a.).
The htonl/ntohl prbem mentioned earliers was fixed by inserting 
"#include <winsock2.h>" into qemud/remote_protocol.c.
I also had errors about fprintf in proxy/libvirt_proxy.c which were 
fixed by inserting "#include <stdio.h>".
Previously I had already discovered src/internal.h needs "#include 
<pthread.h>".
As for make install, I had to comment out the "chmod u+s" line in 
proxy/Makefile, because win32 doesn't support this.
Finally I had an error because config.stat could not be found. I 
resolved this with "ln -s config.status config.stat".
Now it's built I guess the next logical step would be testing.
It's a shame though the tests won't compile.
Any chance they could be rewritten using pthreads instead of fork?
Regards
