Re: [fenics-support] Homebrew formula for Dolfin & co. on OSX

[dpo]

Great initiative! I've tried it and here's my feedback.

1. I'm on Mac OS X 10.10.5.
2. I needed to enter my github username + password at the beginning. Shouldn't be necessary? Use anonymous pull instead of via https?

3. Fails to build petsc4py:

   include "numpy/arrayobject.h"

       ^

   1 error generated. error: command '/usr/local/bin/mpicc' failed with exit status 1

4. Fails to build VTK:

==> Downloading http://www.vtk.org/files/release/7.0/VTK-7.0.0.tar.gz

100,0%

==> cmake -DCMAKE_C_FLAGS_RELEASE=-DNDEBUG -DCMAKE_CXX_FLAGS_RELEASE=-DNDEBUG -\ D ==> make ==> make install Traceback (most recent call last): File "", line 1, in AttributeError: 'module' object has no attribute 'getusersitepackages' Traceback (most recent call last): File "", line 1, in AttributeError: 'module' object has no attribute 'getusersitepackages'

1. How much of this can be automated? Can it be reduced from what is currently 15 lines to 1 line?

2. Can there be multiple packages/formulas like:

   fenics-deps (all dependencies needed for installing/developing FEniCS) fenics (latest stable version, depending on fenics-deps) fenics-dev (latest version from master branch)

[dpo]

1. Should be supported.
2. Not sure why that happens. I never have to do that when I brew tap.
3. petsc4py isn't finding numpy. I presume you're in a virtualenv at this point. Is numpy on your PYTHONPATH?
4. I'm guessing vtk did build and that there's a PYTHONPATH issue. Let's see brew gist-logs vtk.

I'm not sure about automation yet. It seems there are still details to iron out.

You can install all deps with brew install --only-dependencies dolfin. The default, brew install dolfin installs the stable release. The master branch can be installed with brew install dolfin --HEAD. See man brew for more information.
