Hello all,
I just wanted to say that I finally got VTK plotting to work.
Fortunately there was a VTK conda package, so I switched my build system
to a Linux Mint with a proper graphical server and it worked. I tested
the package both in Mint and Arch Linux and I can claim success :)
Let me repeat the commands:
$ conda create --name py27 python=2.7
$ source activate py27
(py27)$ conda install fenics --channel juanlu001
I will repeat the process with the first 1.5 release with updated
requirements, and by then I will probably put all the conda recipes in
an independent Bitbucket repo. Again, any feedback is welcome.
Best regards,
Juan Luis

I think is is great.
I haven’t tested yet, but a suggestion to make the process simpler is to let
PETSc build suitesparse, etc. PETSc is a C library but can be installed with
pip (it has a Python-based build system). It can take care of a number of
dependencies (solvers, graph partitioners, etc).
I’ve copied Andy Terrel at Conitnuum Analytics who might have something to chip
in with.

Hello all,
My name is Juan Luis Cano, I'm studying a MSc in Aerospace Engineering in
Madrid and I started recently to play with FEniCS for my final degree project.
For my day to day work I am using a virtualized Linux Mint and everything works
like a charm thanks to the Ubuntu PPA, but as it is not the distribution which
I normally use I tried to build a conda package these holidays.
I noticed there are a couple of build systems out there (dorsal, hashdist) but,
as the Anaconda distribution[1] is getting popular in the scientific Python
world these days, I really wanted to try to provide FEniCS packages for it (at
least in Linux). For those who don't know it, Anaconda's package manager,
conda, is open source[2] and provides a nice build system[3].
You can try out my progress so far with a Linux 64 bit box and a Python 2.7
environment:
$ conda create --name py27 python=2.7
$ source activate py27
(py27)$ conda install fenics --channel juanlu001
The build process itself was painful because I knew very little about FEniCS
dependencies a week ago but right now I managed to run the `demo_poisson.py`
(_without_ plotting, see below). The results seem OK from Paraview.
The good thing is that I made the builds in an Ubuntu Server box but it works
the same in an Arch Linux machine too. I didn't try to compile it against
PETSc, Trilinos and such yet because I wanted some feedback from the community
first, and know if this is something useful for anybody!
The trick here was avoiding the Ubuntu packages (via apt-get) and compile the
dependencies in the form of conda packages themselves. I did such with boost
and suitesparse, for instance[4]. This way there are no linking problems across
different Linux distros. I am stuck with VTK though because it seems to look
for libGL.so, which in turn pulls from X11... and everythings gets messy very
quickly[5].
So if I can get some feedback about how does this work in others' computers, if
this is any useful and which packages should I try to build next that would be
great. Anybody can reproduce the build process using my conda-recipes fork.
Kind regards and happy new year!
Juan Luis
