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



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?

Hi,
Some time passed by and I thought I'd have another go at compiling libvirt for win32 using MinGW/MSYS again. I tried to compile libvirt-0.4.3 and I got around most obstacles. Now it just seems I am stuck when it is trying to link. My search on google showed me that I am not the first one to see this issue. Usually i means -lws2_32 is in the wrong place. However I tried moving it around without luck. Also it doesn't make sense to me that only htonl and ntohl are missing. It appears anything else used from the winsock library is found during linking. I feel we're very close to getting libvirt compiled on win32. Or do you know if anyone already succeeded?
