hi folks, as you might have already noticed, we've made the switch to C++20. see Casey's mail sent to this mailing list a couple days ago. another thing you need to pay attention to is, we now need to use at least gcc-11 or clang-12 for compiling the tree. if your working flows depend on the stock C++ compiler in your distro, you might need to check the version to make sure that its C++20 support. see also https://en.cppreference.com/w/cpp/compiler_support#cpp20 . for instance, if you are using ubuntu focal, you could use the ppa repo at https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test or prebuilt clang-12 or up at https://apt.llvm.org. if you are using centos/RHEL 8, you might want to use gcc-toolset-11 or gcc-toolset-12 or llvm-toolset-12 . apparently, we are not using all the C++20 features, but we are starting exploring some of them. as some of us have noticed, we have started using https://wg21.link/P1185R2 in the main branch. because we are now using both gcc-11 and clang-12 in our CI/CD workflows, we can assure you that these two compilers should be able to compile the main branch. i apologise for any inconvenience caused. cheers, -- Regards Kefu Chai _______________________________________________ Dev mailing list -- dev@xxxxxxx To unsubscribe send an email to dev-leave@xxxxxxx
