[Pkg-libvirt-maintainers] Bug#996313: ruby-libvirt: FTBFS with ruby3.0: common.c:27:10: fatal error: st.h: No such file or directory

Source: ruby-libvirt
Version: 0.7.1-1
Severity: serious
Justification: FTBFS

Hi,

We are about to enable building against ruby3.0 on unstable. During a test
rebuild, ruby-libvirt was found to fail to build in that situation.

To reproduce this locally, you need to install ruby-all-dev from experimental
on an unstable system or build chroot.

Relevant part (hopefully):
> gcc -fdebug-prefix-map=/<<PKGBUILDDIR>>=. -I. -I/usr/include/x86_64-linux-gnu/ruby-3.0.0 -I/usr/include/ruby-3.0.0/ruby/backward -I/usr/include/ruby-3.0.0 -I.  -DRUBY_EXTCONF_H=\"extconf.h\" -Wdate-time -D_FORTIFY_SOURCE=2   -g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat -Werror=format-security -g -O2 -ffile-prefix-map=/build/ruby3.0-2KsnwC/ruby3.0-3.0.2=. -fstack-protector-strong -Wformat -Werror=format-security -fPIC   -o common.o -c common.c
> common.c:27:10: fatal error: st.h: No such file or directory
