Description Martin Jambor 2024-07-16 15:46:18 UTC 
Package libyui does not build with gcc14, as can be seen here:

https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/qemu/standard/x86_64

The error that stops the build is (a warning promoted to an error):

Normally, one is able to reproduce such failures locally with
  osc build --clean --noservice --alternative-project home:rguenther:nextgcc
but for some reason obs always fails with " error: Failed build dependencies" when building qemu locally for me.

About the local build:
Does it complain about xen and spice? It seems the local osc has an issue with the way qemu.spec does `%include common.inc`. A workaround is to edit the spec to hardcode the common.inc contents, or use `osc build --without <dep>` to exclude the dependencies.
Comment 2 Martin Jambor 2024-07-18 09:19:41 UTC 
Just inserting the contents of common.inc instead of the line that attempts to include it works.  Thanks.
