I think the only prerequisite is to install 'liburing-devel' package (Fedora 32) on the build system, and then fdmon-io_uring.c will be built. I'll try to add a gitlab job ;-) Thanks, Stefano > > > > > This patch fix the issue adding 'linux_io_uring' dependency for > > fdmon-io_uring.c > > > > Fixes: a81df1b68b ("libqemuutil, qapi, trace: convert to meson") > > Cc: pbonz...@redhat.com > > Signed-off-by: Stefano Garzarella <sgarz...@redhat.com> > > --- > > util/meson.build | 2 +- > > 1 file changed, 1 insertion(+), 1 deletion(-) > > > > diff --git a/util/meson.build b/util/meson.build > > index 23b8ad459b..e6b207a99e 100644 > > --- a/util/meson.build > > +++ b/util/meson.build > > @@ -4,7 +4,7 @@ util_ss.add(when: 'CONFIG_ATOMIC64', if_false: > > files('atomic64.c')) > > util_ss.add(when: 'CONFIG_POSIX', if_true: files('aio-posix.c')) > > util_ss.add(when: 'CONFIG_POSIX', if_true: files('fdmon-poll.c')) > > util_ss.add(when: 'CONFIG_EPOLL_CREATE1', if_true: files('fdmon-epoll.c')) > > -util_ss.add(when: 'CONFIG_LINUX_IO_URING', if_true: > > files('fdmon-io_uring.c')) > > +util_ss.add(when: ['CONFIG_LINUX_IO_URING', linux_io_uring], if_true: > > files('fdmon-io_uring.c')) > > util_ss.add(when: 'CONFIG_POSIX', if_true: files('compatfd.c')) > > util_ss.add(when: 'CONFIG_POSIX', if_true: files('event_notifier-posix.c')) > > util_ss.add(when: 'CONFIG_POSIX', if_true: files('mmap-alloc.c')) > > >
