Hi, I'm trying to build a DEBUG version of Ceph Reef on a virtual Ubuntu-LTS 22.04 running on Lima by following the README on Ceph's github repo. The build failed and the last CMake error was ""g++-11: error: unrecognized command-line option '-Wimplicit-const-int-float-conversion'". Does anyone know what I can do to fix the compilation error? I could try different gcc versions, but I'd assume Ceph's build scripts would install and verify all the dependencies. Thanks, The system configuration is as follows:
uname -a Linux lima-ceph-dev 5.15.0-86-generic #96-Ubuntu SMP Wed Sep 20 08:23:49 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.3 LTS Release: 22.04 Codename: jammy
I followed the instructions on the README in Ceph's github repo: https://github.com/ceph/ceph, and the command ./do_cmake.sh failed at step [137/2150] that builds frontend dashboard with the error message "ninja: build stopped: subcommand failed." The last error logged in the file CMakeError.log has to do with "g++-11: error: unrecognized command-line option '-Wimplicit-const-int-float-conversion'". Below the last error message on the CMakeError.log: Performing C++ SOURCE FILE Test COMPILER_SUPPORTS_WARN_IMPLICIT_CONST_INT_FLOAT_CONVERSION failed with the following output: Change Dir: /home/dyuan.linux/ceph/build/CMakeFiles/CMakeTmp Run Build Command(s):/usr/bin/ninja cmTC_bab6d && [1/2] Building CXX object CMakeFiles/cmTC_bab6d.dir/src.cxx.o FAILED: CMakeFiles/cmTC_bab6d.dir/src.cxx.o /usr/bin/g++-11 -DCOMPILER_SUPPORTS_WARN_IMPLICIT_CONST_INT_FLOAT_CONVERSION -fPIE -Wimplicit-const-int-float-conversion -std=c++20 -o CMakeFiles/cmTC_bab6d.dir/src.cxx.o -c /home/dyuan.linux/ceph/build/CMakeFiles/CMakeTmp/src.cxx g++-11: error: unrecognized command-line option '-Wimplicit-const-int-float-conversion' ninja: build stopped: subcommand failed.
