A long time ago I added the %enable_devtoolset9 macro to make this easier,
you might want to try that.  But I don't think it has (m)any users, so
I can't guarantee that it works as expected.

Not sure if it is a real package (or if this
is even the way it should be done), but I
have seen the following in spec files
along with the needed (for your package)
(%if ...) tests for epel8.

  BuildRequires:  gcc-toolset-9

and at the top of the %build section:

  source scl_source enable gcc-toolset-9 >/dev/null 2>/dev/null && true || true

As I recall, depend on what that package
requires/is doing in other sections one may
also need to do the same source scl_source
in those sections.

Good luck.

Is there any real package .spec that use cc-toolset-9 as example?
SCL documentation is too extensive and mostly about creating new SCL,
I cannot find short description how simply to make one new package using modern 
C++.

The package name is gcc-toolset-9 and it is a SCL so you need to set up the
build environment like it is using other SCL's with an `scl enable` in the
spec file.

I've seen things you people wouldn't believe. Flame wars in
sci.astro.orion. I have seen SPAM filters overload because of Godwin's Law.
All those moments will be lost in time... like posts on  BBS...

Maybe one hasn't been published? I find that https://rpm.pbone.net/ is
really, really useful for this kind of search for an RPM.

Packaging for EPEL8 with gcc-9+

[Евгений Пивнев]

May be this is trivial question but I cannot find how to package application 
for EPEL8 that requires C++17+
Adding «Requires: gcc-toolchain-10» into *.spec not helps.
