Failed to build clang-9.0: command execution failed - Mac OS X big Sur 11.0.1

[tiperiu]

Hi,

Just updated to the latest mac os, I installed the command lines tools (note that the instruction on the macport site are obsolete for this) I was in the process of reinstalling my sports from the old system, I had many errors - the first of which is this one when installing clang-9.0 (required by qt5-qtcreator)

thank you

Replying to tiperiu:

I installed the command lines tools (note that the instruction on the macport site are obsolete for this)

Which URL, which instructions specifically?

The main.log says the problem is:

:info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_llvm-9.0/clang-9.0/work/llvm-9.0.1.src/projects/compiler-rt/lib/sanitizer_common/sanitizer_platform_limits_posix.cc:169:31: error: invalid application of 'sizeof' to an incomplete type 'struct stat64'
:info:build   unsigned struct_stat64_sz = sizeof(struct stat64);
:info:build                               ^     ~~~~~~~~~~~~~~~

So this is a duplicate of #61477.
