[Users] Can't build on Mac OS Catalina

[Murray Wolinsky]

Hi All,

I'm unable to build the Einstein Toolkit on Mac OS Catalina. Has anyone
done so -- and do you have suggestions?

When I try to run ./simfactory/bin/sim build -j2 --thornlist ../
einsteintoolkit.th I get the following error:

Cactus requires a C++11 compiler -- check your C++ compiler and C++
compiler flags

I know that the Mac makes it very difficult to use gcc instead of clang,
but AFAICS I'm using the Homebrew gcc-11 compiler (Homebrew GCC 11.1.0_1)
11.1.0) and setting the options and flags properly in both the files
OptionsList and generic-11.cfg :

Setting CC to 'gcc-11'
Setting CXX to 'g++-11'

Setting CXXFLAGS to '-g -std=gnu++11'

etc.

Do I need to set environment variables? Is there some other toolkit file I
should l modify?

I appreciate any help anyone can provide!

Thanks in advance!

Murray
