Description Fedora Release Engineering 2020-08-03 17:46:37 UTC 
libcxxabi failed to build from source in Fedora rawhide/f33

https://koji.fedoraproject.org/koji/taskinfo?taskID=47992683


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_33_Mass_Rebuild
Please fix libcxxabi at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
libcxxabi will be orphaned. Before branching of Fedora 34,
libcxxabi will be retired, if it still fails to build.

Set the toolchain to clang which helps considerably.  But there's still an armv7hl failure:

CMake Error at /usr/share/cmake/Modules/CMakeTestCCompiler.cmake:66 (message):
  The C compiler
    "/usr/bin/clang"
  is not able to compile a simple test program.
  It fails with the following output:
