Mac OS Installation
Minimum System Requirements
In general, the following is required for MOOSE-based development:
C++11 compliant compiler (GCC 4.8.4, Clang 3.4.0 or greater)
(included in any of our redistributable packages if you choose to install one)
Memory: 16 GBs (debug builds)
Processor: 64-bit x86
Xcode Command Line Tools (CLT). To install CLT on your machine, open a terminal and run:
If you do not have CLT installed, you will be presented with a dialog box allowing you to install CLT.
Additionally, for OSX Mojave (10.14), you also need to install the header package:
Download and install XQuartz
Install one of our redistributable packages pertaining to your OS X version:
Mojave 10.14: moose-environment_osx-mojave_20181203_x86_64.pkg
High Sierra 10.13: moose-environment_osx-highsierra_20181203_x86_64.pkg
Sierra 10.12: moose-environment_osx-sierra_20181203_x86_64.pkg
Internal INL users may obtain the latest redistributable packages from the following location:
If you have any opened terminals at this point, you must close and re-open them to use the MOOSE environment. The following instructions will ultimately fail if you do not.
Obtaining and Building MOOSE
To install MOOSE run the following commands in a terminal.
mkdir ~/projects cd ~/projects git clone https://github.com/idaholab/moose.git cd moose git checkout master
The master branch of MOOSE is the stable branch that will only be updated after all tests are passing. This protects you from the day-to-day changes in the MOOSE repository.
MOOSE directly relies on the libMesh finite-element framework. Because of this strong tie MOOSE contains a particular version of libMesh that we have vetted for our users. To pull down and compile this version of libMesh you simply need to run a script in MOOSE:
cd ~/projects/moose ./scripts/update_and_rebuild_libmesh.sh
Do not use
sudo when running update_and_rebuild_libmesh.sh.
Compile and Test MOOSE
After libMesh has compiled the next step is to compile and test MOOSE.
cd ~/projects/moose/test make -j 4 ./run_tests -j 4
If the installation was successful you should see most of the tests passing (some tests will be skipped depending on your system environment).
MOOSE does not use traditional versioning, is under heavy development, and is being updated continuously. Therefore, it is important that you continue to update MOOSE as you use it to develop your application(s), we recommend weekly updates.
To update MOOSE use the following commands.
cd ~/projects/moose git fetch origin git rebase origin/master
Then return to your application, re-compile, and test.
cd ~/projects/YourAppName make -j4 ./run_tests -j4
