--- Comment #5 from Vedran Miletic <ved...@miletic.net> --- (In reply to Michael Osipov from comment #4) Sensible approach, I assume that's the way to fix it properly. For those who are hit by this bug and don't want to search for install media, extract tarballs etc., here's a another, simpler approach that seems to work just as well. I can confirm that Clang is usable as I compiled GROMACS (C++) with several different CMake configurations just to verify that. Assuming machine can access the internet, as root do the following: # cd /usr/include/c++/v1 # mkdir __string # cd __string # fetch https://raw.githubusercontent.com/freebsd/freebsd-src/releng/14.0/contrib/llvm-project/libcxx/include/__string/char_traits.h # fetch https://raw.githubusercontent.com/freebsd/freebsd-src/releng/14.0/contrib/llvm-project/libcxx/include/__string/extern_template_lists.h -- You are receiving this mail because: You are the assignee for the bug.
