InstallFiPy%2FMacOSX%2FSnowLeopard
The following generally follows http://blog.hyperjeff.net/?p=160 (Last updated: Wed, Nov 11, 2009, 4:03am), but had to be modified somewhat.
* Be sure to use the "System" python. The ones from http://www.python.org and [http://www.activestate.com/activepython/ ActiveState] don't appear to build proper 32/64 Universal libraries. You want `/usr/bin/python`. Make sure your `$PATH` isn't picking up another one. You may also need to set aside any `python` executable in `/usr/local/bin`.
* Make sure that `/sw` ([http://www.finkproject.org fink]) and `/opt` ([http://www.macports.org !MacPorts]) are not on any of your `$PATH`s. There may be viable ways to get running with those (and we will explore them in the future) but they aren't compatible with this one.
Finally, this has all been written as though you're using `bash` (which is the Snow Leopard default). If you're using a `tcsh` variant, then you'll need to replace all of the `export` statements with appropriate `setenv` statements.
Install Xcode from your Snow Leopard install DVD or from the Apple Developer site.
This is the main departure from hyperjeff's instructions. virtualenv avoids the need to meddle with the System's NumPy and is just generally a cleaner way to work.
* Install [http://pypi.python.org/pypi/distribute distribute],
* ''alternatively, you can install [http://pypi.python.org/pypi/setuptools setuptools], but distribute
seems to be the more "modern", supported way to accomplish the same
tasks. With `setuptools`, you will need to replace each instance of `pip install` with `easy_install`.''
* Install [http://www.pip-installer.org/en/latest/index.html pip]
* Install [http://pypi.python.org/pypi/virtualenv virtualenv]
* Optionally (recommened) install [http://www.doughellmann.com/projects/virtualenvwrapper/ virtualenvwrapper]
and add
to your `.bashrc` file (or other appropriate startup file).
* Set up your virtual environment
Substitute any name you like for `{python64}`.
* ''if you didn't install `virtualenvwrapper`,
''
E.g.
Get and install gfortran. There are various other ones out there, but this one is strongly advised.
You can do this all graphically, and you should be sure to check for the latest version, but you can do this from the command-line
Install CMake. I used `cmake-2.8.4-Darwin-universal.dmg`.
This one must be done with the GUI.
From now on, particularly if you take a break or open a new shell, be sure your virtual environment is active before each step, e.g.,
* Build
* Optionally, test with
* Install
Download and unpack the SuiteSparse code archives
* Download, unpack, and build [http://glaros.dtc.umn.edu/gkhome/views/metis METIS] within the `SuiteSparse` directory
* If necessary, rename the metis directory, e.g.,
''(or change every instance of `metis-4.0` to `metis-4.0.3` in every `Makefile`. I thought it was easier to rename the directory)''
* Build
* If desired, test `METIS` by following the directions in `Graphs/0README`.
* Go back to `SuiteSparse`
* In `UFconfig/UFconfig.mk`, around line 281, uncomment
Note that this file has been updated since hyperjeff's instructions and that `-arch i386 -arch x86_64` from hyperjeff's instructions is not in the commented-out lines in the package I downloaded. I omit them to no apparent harm.
* Build
No need to install this.
* Ensure that you have installed [wiki:SnowLeopardSourceBuild#FFTW FFTW]
* Ensure that you have installed [wiki:SnowLeopardSourceBuild#UMFPACK UMFPACK]
* Set up the build environment
* Get the source
* ''You might choose instead to
or [https://sourceforge.net/projects/numpy/files/ download a tarball],
depending on your level of risk aversion.''
* Tell NumPy about AMD and UMFPACK
Edit `site.cfg`, around line 99
* Build and install
* Optionally, to test * Leave the `numpy` directory
* Install [http://somethingaboutorange.com/mrl/projects/nose nose]
* Test
* Get the source
* I had to apply attachment:makeosx.patch
Basically `zlib` is now at version 1.2.5, the `make` and the `install` of `zlib` need to be separate steps, and the `libpng` file repository has been rearranged. See http://sourceforge.net/tracker/?func=detail&aid=2981126&group_id=80706&atid=56072 (which has been incompletely applied to the Matplotlib source, as of this writing) and https://sourceforge.net/tracker/?func=detail&aid=3141312&group_id=80706&atid=560722.
* Build and install
* Test
* Get, build, and install the source
* Optionally, to test
I get one failure in `Test/test_sparray.py` and a segmentation fault in `Test/test_superlu.py`, but Pysparse seems to work fine for FiPy's needs.
Get the source
It is not necessary to install FiPy (we don't).
* Simply add an appropriate
{{{
export PYTHONPATH=/{path}/{to}/fipy:${PYTHONPATH}
}}}
to your `${VIRTUAL_ENV}/bin/postactivate` file (best to move the `fipy/` directory you just checked out to a more permanent home than `~/fipytmp`) and then
{{{
python setup.py bdist_egg
}}}
* Alternatively, install like other packages with
{{{
python setup.py install
}}}
* Perhaps the best of both worlds is to move `fipy/` to someplace permanent and then
{{{
python setup.py develop
}}}
which will cause FiPy to be "installed", but will allow you to `svn update` the source when we make changes.
At this point, FiPy should be basically functional. The following installs augment FiPy's capabilities, but some of them can be troublesome (or at least time-consuming) to build and install, so you may wish to wait until you need them.
Do NOT move the System NumPy library. virtualenv takes care of this.
Get the source
You might choose instead to
or download a tarball, depending on your level of risk aversion.
Now compile and install
Note, I had to add the `--fcompiler=gnu95` option to hyperjeff's instructions.
Get, build, and install the source
Clean up your build environment. Either launch a new shell and
or
If you have previously installed or built a custom Python, e.g., from python.org or from ActiveState, then you may have a `/Library/Frameworks/Python.framework`. If you do, it is imperative that the VTK build not see this. You can either move that framework aside (requiring `sudo`) or you can divert CMake's attention with
If, for some reason, you already have a `~/Library/Frameworks/Python.framework`, then you'll need to move that aside, whether or not you have a `/Library/Frameworks/Python.framework`. CMake is hard-wired to search, in order, for `~/Library/Frameworks/Python.framework`, `/Library/Frameworks/Python.framework`, `/System/Library/Frameworks/Python.framework`, and finally `/Network/Library/Frameworks/Python.framework` and we need it to find `/System/Library/Frameworks/Python.framework`. If anybody knows a CMake flag to direct it to do that, please pass it along.
Download, build, and install VTK
You'll also need to add
to your `${VIRTUAL_ENV}/bin/postactivate` script.
Now follow the standard Mayavi build instructions of your choice. I did:
Download, build, and install ETS
Download, build, and install Mayavi
Download, build, and install sip
Install the Cocoa version of Qt. Be sure to get the "32-bit and 64-bit" installer.
Download, build, and install !PyQt
!PyTrilinos requires swig 1.3.38 or greater. You can check what you have with
Otherwise, download the latest from http://www.swig.org/download.html, unpack, and build
FiPy needs mpi4py for some aspects of parallel operations. If you only plan to use Trilinos in serial (you do? really?), you don't need this.
Obtain Trilinos 10
You'll also need to add
to your `${VIRTUAL_ENV}/bin/postactivate` script.
It is not clear why it is necessary to disable the Fortran compiler, but cmake fails otherwise.
Python 2.7.x has known problems with building some libraries for Mac OS X.
`${VIRTUAL_ENV}/include/python2.7` is a symlink. Find what it links to and replace it with a copy, e.g,
This will produce something like
Note the link destination and replace the link with a copy of that directory:
Search for `_PY_PORT_CTYPE_UTF8_ISSUE` in `${VIRTUAL_ENV}/include/python2.7/pyport.h` and make the changes (lifted from http://codereview.appspot.com/179049/patch/1/2)
Obtain Trilinos 10
You might wish to keep it around to perform other installs, but you're done with `~/fipytmp`, so, if desired, you can
There's a new gfortran in town. It seems to be easiest to get this with homebrew.
