Hi Vladislav, It seems the last two files should have .c extension rather than .m. Unlike Cocoa UI code, the files do not contain Objective-C classes. They are just C code with blocks (which is supported by compilers shipped with Xcode SDK), e.g this program can be compiled without extra compiler flags: $ cat block.c int main() { int (^x)(void) = ^{ return 0; }; return x(); } $ cc block.c && ./a.out $ Regards, Roman > net/vmnet-host.c | 24 ++++++++ > net/vmnet-shared.c | 25 +++++++++ > net/vmnet_int.h | 25 +++++++++ > qapi/net.json | 133 +++++++++++++++++++++++++++++++++++++++++++- > 9 files changed, 278 insertions(+), 2 deletions(-) > create mode 100644 net/vmnet-bridged.m > create mode 100644 net/vmnet-common.m > create mode 100644 net/vmnet-host.c > create mode 100644 net/vmnet-shared.c > create mode 100644 net/vmnet_int.h > > diff --git a/net/clients.h b/net/clients.h > index 92f9b59aed..c9157789f2 100644 > --- a/net/clients.h > +++ b/net/clients.h > @@ -63,4 +63,15 @@ int net_init_vhost_user(const Netdev *netdev, const char > *name, > > int net_init_vhost_vdpa(const Netdev *netdev, const char *name, > NetClientState *peer, Error **errp);
