Hello Corrado,
In case you are willing to try other options, you might want to check
out the conda recipes I recently created:
https://github.com/Juanlu001/fenics-recipes
I have successfully used them to build FEniCS in several Linux
distributions. I don't have a Mac so I cannot try in OS X but in
principle they should work.
You can also add recipes for more packages, for example SLEPc:
https://github.com/Juanlu001/conda-recipes/tree/juanlu001/fenics/slepc
I can provide help and guidance if you finally try to build the packages
using these recipes.
Regards,
Juan Luis Cano

I was the one helping Claire, so I try give you some more details and
I take the opportunity to give some feedback on hashdist install after
spending almost two days compiling:
General remarks:
1 - hashdist is nice, but I was not able to install with slepc4py only
using hashdist.
2 - I found http://fenicsproject.org/fenics-install.sh interesting as
an example for personalise script, but I do not like the “one-click”
install philosophy and I would not recommend it to newcomers, because:
(i) if you have any problem during the installation you have no idea
bout how to solve (and it is very likely you have a problem, if you do
not have a completely clean os)
(ii) if you want to change the settings (e.g. add slepc4py) you have
no idea about what to do.
(iii) you completely loose the control about what it is happening and
your system, and it is not evident at all to track what the script is
doing.
3 - I think that hashdist should be used by adopting/modifying the
profile fenics.Darwin.yaml provided in the examples in hashdist (and
eventually tuning its setting for your system) and using hashdist with
“hit build” being aware of what you are doing. In my opinion this
method should be documented on the fenics website.
4 - It is not evident to select the best practice to let hashdist
interact with your generic package manager (homebrew/macport). In my
understanding hashdist is not designed to be a replacement of a
generic package manager, but to work on top of it.
My current solution is a mix, maybe not optimal, and not yet definitive:
- As a general practice I try to stick to system compilers (clang)
and system python (2.7). A big issue is that very often you do not
understand which one of the many python installed in your system you
are using.
- I use homebrew as generic package manager. I use it to install
generic dependencies as cmake, boost, vtk, eigen, openmpi, libxml … I
also install gcc with homebrew to have a fortran compiler, but then I
use clang to compile c, c++
- I install petsc/slepc/petsc4py/slepc4py manually with my own
PETSC_DIR and PETSC_ARCH, letting petsc install all the dependencies
like parmetis, metis, super_dist, ml, ...
- I use hashdist to install only ffc/ufl/instant/…/dolfin stack,
eventually with different profiles (e.g., 1.5, development,
yournewbranch). To do this you have to modify the fenics.Darwin.yaml
profile to use host packages for whatever it is already installed
(boost, vtk, petsc, slepc, slepc4py, hd5)
I hope it may give an idea … but it is not "one-click" if you want to
have control on your system …
Otherwise I think the only “easy” solution is to use binary (and I
think that it is important that are provided with all possible
dependencies) or a virtual machine with fenics-virtual.
In particular, I teach a master class using fenics, and I do not even
talk about compiling for source to students. I suggest two options:
binaries (if they works) or virtual-fenics. And this year 38 students,
not proficient with programming and os-menagement, were able to use it
without my help from macsox/linux/windows … The case of Claire is
different, because she need special feature, namely petsc4py (and she
is not a master student!).

Hi,
could you please share how you installed FEniCS on Mac? Did you use
dorsal, hashdist, …?
Thanks.

Hello,
I installed FEniCS from source on my computer (mac OS Yosemite),
and I wish to work with slepc4py. What is the best way to install it ?
Thanks in advance,
