What is the use case for annobin without gcc-toolset-*?  annocheck?  Thanks.

Fixed in: gcc-toolset-9-annobin-8.77-3.el8

Not sure I understand.  gcc-toolset-* expands also e.g. to gcc-toolset-9-ltrace
and that's clearly unrelated.  gcc-toolset-9-annobin in combination with
gcc-toolset-9-gcc might be used for compilation using rpm macros coming from
redhat-rpm-release (per bz1727303).  If annobin is installed without any other
gcc-toolset-9 package but gcc-toolset-9-runtime, then, yes, the use case is 
just annocheck, as you say, I think.

... so maybe gcc-toolset-9-annobin-annocheck.rpm should Require gcc-toolset-9-runtime, and gcc-toolset-9-annobin.rpm should Require gcc-toolset-9-gcc (+ possibly gcc-toolset-9-runtime) (?)

I was just wondering what the use case is for installing gcc-toolset-9-annobin by itself.  If the meta-package pulls in everything (despite being named gcc-*), that's indeed too much.

From a pure correctness perspective, I think gcc-toolset-9-gcc should have a dependency like this:

Requires: (gcc-toolset-9-annobin if annobin)

So if you have system annobin installed, you also get the GTS version of it.

(Sorry for derailing your bug report.)

Nick, thanks for looking into this.  We are not quite there yet though, it seems:

=======
   8.1 Server x86_64 # yum install gcc-toolset-9-annobin-8.77-3.el8.x86_64.rpm 
[ ... stuff deleted ... ]
Error: 
 Problem: conflicting requests
  - nothing provides /opt/rh/gcc-toolset-9-gcc/enable needed by gcc-toolset-9-annobin-8.77-3.el8.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

Sounds good, plus I think that gcc-toolset-9-annobin should depend on gcc-toolset-9-gcc,
since without it, it is of no use.

Sorry, I used the wrong scl macro (scl_require insted of scl_require_package).
This should now be fixed in gcc-toolset-9-annobin-8.77-4.el8, but I will wait
for the gating tests to pass before changing this BZ.

CI gating has passed - yay - setting to MODIFIED.
