Hm.. I'm failing to reproduce the build error, even though I put
sleep(5) into both src/rpc/gendispatch.pl and src/rpc/genprotocol.pl and
I try in a machine with 384 cores. I even wrapped rpcgen in a shell
script to insert a short sleep.
In the commit message you mention libvirt-8.1.0, does this problem still
occurs even with the current master?
Thanks for taking care of this.
Yes, this is a rare case. We build libvirt everyday and only saw this twice so
far. We haven't upgraded to a newer version. Even if it's done, we might not
expect it's reproduced soon...indeed
Looking at the meson.build, the dependencies are still missing on current
master.
