The policy update will also recommend that packagers use standardized
macro names when using conditional options to control the compiler
choice:
%bcond_with toolchain_clang
%bcond_with toolchain_gcc
replacing current
%global toolchain clang
or
%global toolchain gcc
described at
https://src.fedoraproject.org/rpms/redhat-rpm-config//blob/rawhide/f/macros#_41
?
No, you would still need to use the toolchain macro. The bcond_with is for adding
an option that you can pass to rpmbuild or mock to control the compiler. I will
try to add a full example to the packager guidelines so this is clear, but if
you wanted to add the option to build with clang, while still using gcc by default,
then your spec file would look like this:
%bcond_with toolchain_clang
%if %{with toolchain_clang}
%global toolchain clang
%endif
