[llvm-dev] Fix builds on MacOS Mojave [patch]

Hi!

I get build failures on Macos 10.14 Mojave.

How-to-repeat:
$ git clone <llvm-project>
$ cd llvm-project && mkdir build && cd build
$ cmake -G"Unix Makefiles" ../llvm
$ make # or "make -j${N}"
:

[llvm-dev] Fix builds on MacOS Mojave [patch]

On an OS X install with Xcode, /opt/ is not expected to contain anything in
particular; it doesn't make sense to hard-code it into the LLVM build
system.

Are you trying to use homebrew to build LLVM?

[llvm-dev] Fix builds on MacOS Mojave [patch]

I get burned one thing or another almost every time I upgrade XCode.
Recently I ran into this problem, but chose to solve it locally by adding
the following to my cache file:

set(CMAKE_C_FLAGS "-I/opt/local/include ${CMAKE_C_FLAGS}" CACHE STRING
"")
set(CMAKE_CXX_FLAGS "-I/opt/local/include ${CMAKE_CXX_FLAGS}" CACHE
STRING
"")

I use macports, which installs this stuff in /opt.

I sorta gave up on OSX working out of the box, so I patch as I go...

hth...

[llvm-dev] [EXT] Fix builds on MacOS Mojave [patch]

Hi

I have macports, but I'm not directly using it - it's just being found
by the build process somehow.

The failure shows that /opt/... is being used, but that usage seems broken or
incomplete.
