Thank you for your review and the explanation, Jonathan. Of course, the reason why I bumped to "libstdc++ < 8.0.0" is that the version 8.0.0 has been pushed to Fedora only recently, after I had written the patches. > I'd be tempted to simply remove the version, so just have > Requires: libstdc++, or maybe Requires: libstdc++ >= 3.4.0 because > it's unlikely that libstdc++ will introduce an ABI break before that > spec file becomes obsolete. But maybe I'm not conservative enough :-) What about the things like: Requires: libstdc++.so.6 or Requires: libstdc++.so.6(GLIBCXX_3.4) ?
