Hi relax-users,
for everyone who is using relax in scripting mode and doesn't like fink or
MacPorts, this could be interesting: It's really easy to install relax via the
"Homebrew" package manger. (see http://mxcl.github.com/homebrew/)
So here is how you do it:
* download and install Apple's Xcode
* install the "Command Line Tools" from inside Xcode
* install Homebrew by typing into your Terminal:
ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"
* install python 2.7 with pip, etc on board, scons for relaxation
fitting and wxPython for a native Mac GUI:
brew install python scons wxmac
* install numpy via pip (don't install scipy, as it causes problems with scons!)
pip install numpy
* download the relax source release
(e.g. http://download.gna.org/relax/relax-2.1.2.src.tar.bz2)
* unpack it into a seperate directory inside /usr/local/
* cd into the directory, type "scons" to make the relaxation fitting modules
* link the relax main program into /usr/local/bin
That's it.
What should also be easy is to make an "official" package, called "recipe".
After entering "brew create [relax-tarball]" a recipe is created where
dependencies and installing instructions are noted. See my non-functional
attempt at the end of this mail to see what I mean.
Any help on making a recipe would be very much appreciated, since I don't know
any ruby.
Have fun,
martin
