<pre>I'm working on an old PowerMac. I am trying to build LLVM/Clang from sources.
MacPorts does not provide an updated Clang compiler. I am bootstrapping the
process with MacPorts GCC 5 compiler (to satisfy the GCC 4.8 minimum).
My build script works fine on Fedora 29 x86_64. On the PowerMac it is having
some trouble. The build script is at <a href="https://github.com/noloader/build-llvm">https://github.com/noloader/build-llvm</a> .
On the PowerMac the script hangs at:
-- Performing Test COMPILER_RT_HAS_WD4722_FLAG
-- Performing Test COMPILER_RT_HAS_WD4722_FLAG - Failed
-- Performing Test COMPILER_RT_HAS_WD4800_FLAG
