This is mostly a reminder to myself:
1) Install Xcode command line tools
2) Install Homebrew
3) Install the following packages using brew install XXX:
brew install gcc lapack boost gsl wget eigen pkg-config cmake libomp
3.5) On a fresh copy of OSX, linking will be fine; however you may find that, many of these will not be properly linked, since many /usr/local/bin directories are not owned by the owner (??!) brew doctor will tell you what is not linked, then brew link XXX will tell you what needs an ownership change, each of which can be done in the form (where you just need to change the relevant path):
sudo chown -R `whoami`:admin /usr/local/bin
4) open-mpi needs to be installed separately (i.e. without Homebrew). Go to https://www.open-mpi.org and follow the installation instructions.
5) get Gambit:
git clone https://github.com/patscott/gambit_1.1.git
(or whatever the repo you want is)
6) build gambit
cd gambit mkdir build
Now, gcc on OSX is a lie. It really calls clang. You want:
cmake -D CMAKE_CXX_COMPILER=g++-8 -D CMAKE_C_COMPILER=gcc-8 -D CMAKE_Fortran_COMPILER=gfortran-8 ..
7) make the scanners:
make -j4 scanners
(4 can be replaced by however many cores you have, you fancy person)
8) do the cmake step again
cmake -D CMAKE_CXX_COMPILER=g++-8 -D CMAKE_C_COMPILER=gcc-8 -D CMAKE_Fortran_COMPILER=gfortran-8 ..
9) actually build gambit
make -j4 gambit
10) if that worked, test it!
cd .. ./gambit backends ./gambit scanners
and make whatever you need by going back to the build
11) you should be in business. If gambit throws an error that looks pythony, try
export PYTHONHOME=/usr/lib/python2.7/ export PYTHONPATH=/usr/lib/python2.7/
(it complains about pythonhome, but really needs both...)
