Overview

Request 777596 superseded

Initial GCC 10 submission, for switching the default runtime libraries
but not yet the default compiler for building packages. Adjust project
config like

# define which gcc package builds the system libraries
%product_libs_gcc_ver 10
...
# The following shlibs have the latest version built from GCC 9 sources
%product_libs_gcc_ver_libasan5 9
%product_libs_gcc_ver_libgo14 9

(I'm not sure if the pp-gcc10 suffix is even right - shouldn't that be unsuffixed, as gcc_libs_ver is 10?

Nevertheless, the conflict with a 2nd package is a bad thing

The -pp packages are always suffixed. But what's a "first time" is that the latest symver of libstdc++ doesn't change between gcc9 (branch) and gcc10 ... I'll see how to fix this - going to be "interesting..."

So... currently we have those packages supplementing gdb and libstdc++6 = %{version} but they do not actually require libstdc++6 = %{version}. So it's possible for the user to forcefully install both. Now, if I add a requires to libstdc++6 = %{version} then the conflicts in that package kicks in and would prevent parallel install of both -pp packages. Unfortunately I'll have to adjust the gcc9 package in a similar way and the fallback mechanism for distros w/o (gdb and ..) style supplements will continue to be broken (we'll hit that with the gcc10 toolchain module for SLE12).

Would that work?

Otherwise I can do Provides: libstdc++6-pp Conflicts: libstdc++6-pp style. That's probably easier...

The Provides/Conflicts sounds like the least error prone and most straight forward approach.
