i am just responding on the list because i think the information is helpful to
others as well, sorry mojca if you weren't expecting that.
-i won't do it in the future if that's the case.
two things: i did manage to get llvm-19 to build without issue on snow leopard.
however it seems there's a problem for clang-19 and higher which is they don't
allow building for 10.6 targets because of x86_64h?
surely this is probably some kind of macro people removed in the past for
clang-17 etc?
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_llvm-19/clang-19/work/llvm-project-19.1.7.src/compiler-rt/cmake/config-ix.cmake
" # Note: In order to target x86_64h on OS X the minimum deployment target
must
# be 10.8 or higher.
if(MIN_OSX_VERSION VERSION_LESS "10.7")
message(FATAL_ERROR "macOS deployment target
'${SANITIZER_MIN_OSX_VERSION}' is too old.")
endif()
"
in short, as it stands: it seems clang-19 doesn't even support 10.6 so this
shouldn't be a concern?
Thanks,
Gagan
