Patch attached. Well, on the new i32 kernel ABI for 64-bit platforms, sizeof(void*)==4 while sizeof(long)==8; on the other hand, for mingw64, sizeof(void*)==8 while sizeof(long)==4. You can't win for all platforms, but for the case of openvz, it seems like we are more likely to be compiled on Linux where sizeof(long) may indeed be the better choice. But I'm okay with your patch to use void*, since the i32 ABI is not popular yet. > +++ b/src/openvz/openvz_conf.c > @@ -195,7 +195,7 @@ virCapsPtr openvzCapsInit(void) > if ((guest = virCapabilitiesAddGuest(caps, > "exe", > utsname.machine, > - sizeof(int) == 4 ? 32 : 64, > + sizeof(void*) == 4 ? 32 : 64, ACK. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
