Installing Chaste on macOS Sierra

This install guide is based upon a fresh install of macOS Sierra.

C++ Compiler

You will need to either:

  • Install Xcode from app store to get the Apple-clang compiler
  • Following the instructions below to install Gcc-7 via Homebrew (it is a dependency of several packages)
    • Note that, by default, g++ is an alias to the Apple-clang compiler

Homebrew

see ​http://mxcl.github.com/homebrew/ 

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Later libraries (PETSc, METIS, VTK and parMETIS) need a "science" repository 

brew tap homebrew/science

Note: I needed to chown some directories to get homebrew 100% happy 

sudo chown USER /usr/local/share/man/de/
sudo chown USER /usr/local/share/man/de/man1/

where USER is your username.

Installing dependencies via Homebrew

To get the latest version of a dependency, you can 

brew install <name>

To get a particular version of a dependency, you can 

brew install <name>@<version>

but this may not be available for all packages.

A full list of packages it's possible to install can be retrieved with 

brew search <name>

For instance, 

brew search boost

gives several options including 

boost # latest version, 1.65, currently incompatible with Chaste
boost@1.55
boost@1.57
boost@1.60

See InstallGuides/DependencyVersions for details on which dependency versions are compatible. Use the following as a guide, but put in specific version numbers, if available, if the default packages are incompatible with Chaste: 

brew install wget 
brew install cmake
brew install boost
brew install xerces-c
brew install metis
brew install parmetis
brew install sundials --with-mpi
brew install hdf5 --with-mpi
brew install vtk
brew install petsc --with-mpi

Codesynthesis XSD

Codesynthesis XSD is not available in homebrew and must be installed directly: 

wget https://www.codesynthesis.com/download/xsd/4.0/macosx/i686/xsd-4.0.0-i686-macosx.tar.bz2
tar -jxf xsd-4.0.0-i686-macosx.tar.bz2

PyCML

pip install --user "python-dateutil==1.5"
pip install --user "rdflib==2.4.2"
pip install --user lxml
pip install --user "Amara==1.2.0.2"

If the above displays an error when installing Amara, try again with: 

sudo easy_install https://pypi.python.org/packages/2.5/A/Amara/Amara-1.2.0.2-py2.5.egg

Adding variables to bash profile

We use the pre-compiled XSD, so must tell CMake where to find it. Edit your bash profile: 

nano ~/.bash_profile

and add 

EXPORT XSD_ROOT=/path/to/xsd-4.0.0-i686-macosx

Additionally, if you wish to use GCC rather than Apple-Clang, also add the following (or similar) to your bash profile: 

EXPORT CC=gcc-7
EXPORT CXX=g++-7

Finishing up

Follow the CMake first run guide.

Handy things

To be able to see the tmp folder in finder use 

sudo chflags nohidden /tmp

Useful aliases to add to ~/.bash_profile 

nano ~/.bash_profile

alias cdchaste='cd /Users/chaste/workspace/Chaste' #Or similar
