Homebrew and BornAgain installation¶
Two things to worry
- Homebrew uses /usr/local but promises not to affect stuff which is installed there by some third party installations
- Particularly, everything goes in /usr/local/Cellar, necessary links in /usr/local/include, /usr/local/lib etc are created.
- When specific package is uninstalled, homebrew removes its links.
- You have to have github account and setup special Github API token to use homebrew
How to install BornAgain
- Install homebrew as described http://brew.sh/
i.e. simply run command below in terminal
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
- Install third party software
brew install git cmake fftw gsl python homebrew/python/matplotlib numpy boost boost-python qt5
- Qt5 issue
- Homebrew calls Qt5 "keg-only", which means that Qt5 is installed into /usr/local/Cellar/qt5 and no links in /usr/local are provided
- This is done for safety, to not to interfere with possible application using Qt4
- For us it leads to BornAgain's cmake which can't find qt installation
- The solution to force linking by giving the command "homebref link --force qt5" is not working (some of FindQtWidget.cmake stuff are not linked correctly.
- The working solution: define PATH=/usr/local/opt/qt5/bin/:$PATH
- Compile BornAgain
cmake -DCMAKE_PREFIX_PATH=/usr/local <source>
