In tbates/umx: Structural Equation Modeling and Twin Modeling in R

OS X installation

Make and install OpenMx.

If you've installed R, Xcode and Fortran (see 2 below), you are ready to make and install OpenMx.

1. In terminal.app, cd to ~/bin/OpenMx/
2. make build # to build he binary bundle in staging or make install to install
3. optionally make test to validate (takes time)

You can also do this from inside R

devtools::build("~/bin/OpenMx", binary = TRUE) system(paste0("open ", .libPaths()[1]))

Setup: Installing needed software

1. Install R and OpenMx's required packages.
2. Install Xcode (on the App Store)
3. Download and install gfortran-nn.n-universal.pkg from https://cran.r-project.org
4. Clone OpenMx into ~/bin/OpenMx (anywhere's fine, but this is standard)

git clone git://github.com/OpenMx/OpenMx.git
cd OpenMx

to get a particular tag

git fetch origin --tags
git checkout v2.21.8

1. Add (or create) the following to mate ~/.R/Makevars

   CC = /usr/bin/gcc CXX = /usr/bin/g++ CXX1X = /usr/bin/g++ FC = /opt/gfortran/bin/gfortran F77 = /opt/gfortran/bin/gfortran

2. Install OpenMP

3. https://mac.r-project.org/openmp/
4. Add the following to ~/.R/Makevars

CPPFLAGS += -Xclang -fopenmp
LDFLAGS  += -lomp

Notes: Usually not necessary now

1. If the RMPI package fails to build with configure: error: "Cannot find mpi.h header file", then it will need to be installed. This used to be via a brew instruction: brew install mpi
2. Run xcode-select --install in a terminal window to get standard C libraries etc
3. note: app store will update it thereafter.
4. You need the correct version of NPSOL for your build. It likely came inside the git repo at "~/bin/OpenMx/inst/npsol/osx/x86_64/libnpsol.a"
   • If not, A copy might be available at the bottom of https://openmx.ssri.psu.edu/wiki/howto-build-openmx-source-repository which you would have to download, rename, and move into position.
