ruby failed to build from source in Fedora rawhide https://koji.fedoraproject.org/koji/taskinfo?taskID=28228587 For details on the mass rebuild see: https://fedoraproject.org/wiki/Fedora_29_Mass_Rebuild Please fix ruby 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, ruby will be orphaned. Before branching of Fedora 30, ruby will be retired, if it still fails to build.

This is the root cause: ~~~ $ cat CMakeLists.txt cmake_minimum_required(VERSION 2.6) install (FILES test.txt DESTINATION bin) $ cmake . -DCMAKE_INSTALL_PREFIX=/tmp/test_rubygems_15764/prefix -- The C compiler identification is GNU 8.1.1 -- The CXX compiler identification is unknown -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done CMake Error in CMakeLists.txt: No CMAKE_CXX_COMPILER could be found. Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH. -- Configuring incomplete, errors occurred! See also "/tmp/test_rubygems_15764/ext/CMakeFiles/CMakeOutput.log". See also "/tmp/test_rubygems_15764/ext/CMakeFiles/CMakeError.log". ~~~ The question is if we should have gcc-c++ available or not. I still think we should not need it and it would be better to fix/disable this particular test, but OTOH: https://bugs.ruby-lang.org/issues/14590
