Arch Linux

@hme Can confirm. I needed to install python2-sympy to build the package, too.

Install wont complete unless you have
python2-sympy
Should it be listed as a dependency?

@gasagna: quite right, I have corrected it (back to what it used to be)

Apparently installing dolfin-git fails on my computer with

==> Building and installing package
==> Install or build missing dependencies for dolfin-git:
error: target not found: instant
error: target not found: ffc
==> Restart building dolfin-git ? [y/N]

However, installing instant-git and ffc-git solves this issue. Can it be automated somehow?

Thanks for the package.

@sparkinson ufc has been merged into ffc so I need to update this package (and ffc-git), in the meantime I'll flag it out of date

I just tried to install this. I can't find ufc-git? I found a message saying that it had been incorporated into dolfin-git. If that is the case, can it be removed from the dependencies?

I think cppunit from [extra] should be a (build) dependency since it the build failed for me without it.

Is PETSC necessary? I could install dolfin, but when building it I got:

Getting build errors which compiling this PKGBUILD (see the pastebin below)
http://pastebin.com/YpBvnBJs

Armadillo is not being detected.
I have armadillo installed in /usr . After seeing some forums, I modified the cmake line of PKGBUILD to:

cmake .. -DCMAKE_CXX_COMPILER=/usr/bin/g++ \
-DCMAKE_INSTALL_PREFIX="${pkg}"/usr \
-DPYTHON_EXECUTABLE:PATH="${py2_interp}" \

-DARMADILLO_INCLUDE_DIRS=${ARMADILLO_DIR}/include \
-DARMADILLO_LIBRARIES=${ARMADILLO_DIR}/lib/libarmadillo.so \
-DCMAKE_BUILD_TYPE="Debug"

It made no difference.
Please help!

Thanks megavolts I have made some changes.

This morning I installed dolfin-git from AUR on a new clean archlinux and ran in several errors, which come from missing dependencies. But I finally went through it.

"Error message" [SOLUTION] :
1) "Could not find a configuration file for package UFC that is compatible with requested version 2.2.0." [install ufc-git]
2)"ARMADILLO_LIBRARIES ARMADILLO_INCLUDE_DIRS ARMADILLO_TEST_RUNSARMADILLO_VERSION ARMADILLO_VERSION_OK) (Required is at least version"2.4.2"" [install armadillo packages]
3) "sh: ffc: command not found" [install ffc-git fiat-git packages ; fiat-git, ufl-git and ufc-git have to be installed manually as they are required by ffc-git. ffc-git calls package name ufl and ufc package name which do not exit in aur.]
4) "ImportError: No module named instant" [install instant-git]


Therefor I will suggest to update the dependencies, adding the following packages:
- ufc-git
- armadillo
- ffc-git (sub dependencies > fiat-git, ufl-git, ufc-git)
- instant-git

Without ffc-git the cmake/scripts/generate* won't work which might result in a compile error due to missing forms (it did here).

This pkgbuild is for the bzr trunk, not version 1.1.

pkgbuild fails with dolfin 1.1.

Changing _bzrtrunk=lp:dolfin/1.0.x works. The 1.0.x branch is maintained for the time being.

All the pkgbuild scripts that I maintain that are relevent for fenics are available at https://github.com/mylese/fenics-arch.git

First time I installed the FEniCS project. Its a bit confusing when installing the bzr packages: when using yaourt it will pull in the non bzr packages as dependencies. As a result I installed them one at the time. Also, I would assume the dependency list of the bzr package is not as complete is the "normal" but orphaned package. Order I took in installing (mostly using yaourt): parmetis, metis, scotch, slepc, trilinos (directly with makepkg, yaourt failed with out of disc space), armadillo, cgal, ufc-bzr, ufl-bzr, fiat-bzr, ffc-bzr, dolfin-bzr (directly with makepkg just to be sure)

My optional package list looks like:

-- The following optional packages were found:
-- -------------------------------------------
-- (OK) OPENMP
-- (OK) MPI
-- (OK) TRILINOS
-- (OK) UMFPACK
-- (OK) PARMETIS

-- (**) SLEPC --> installed, dolfin fails to locate it
-- (**) MTL4
-- (**) CHOLMOD
-- (**) PASTIX
-- (**) SCOTCH --> installed, dolfin fails to locate it
-- (**) VTK

Thanks for making this package!!

I got '/usr' for TRILINOS_DIR too. Sourcing /etc/profile.d/trilinos.sh doesn't make a difference.

What is the result of 'echo $TRILINOS_DIR'? I get '/usr'. It may be that you need to do 'source /etc/profile.d/trilinos.sh' or log in and out again before the environment variable is set. Please report back.

I'm trying to install dolfin using the provided PKGBUILD, but it fails when trying to find armadillo. I've reinstalled armadillo multiple times from AUR, but no go. Every time I try to build dolfin it fails at the ARMADILLO_TEST_RUNS. Any suggestions?

Orphaned, please see http://aur.archlinux.org/packages.php?ID=58971

The latest stable dolfin version is 1.0.0 released on 2011-12-19, and aimed at Ubuntu users. In Arch terms this means that several dependencies are quite 'old' (e.g. the required version of CGAL also requires an earlier Boost). So, whilst it would be possible to make the older fenics work with newer versions of dependencies, and it would be possible to work out how to install older versions of dependencies, I think that Arch Users would rather be using the latest fenics software and, if necessary, make it work on our very fresh systems.

So, I am going to maintain these packages: dolfin-bzr ffc-bzr fiat-bzr instant-bzr ufc-bzr ufl-bzr viper-bzr
and I am going to orphan these: dolfin ffc fiat instant ufc ufl viper, and if no one adopts them (and I can see no reason to do so) they will be deleted in a week.

Just to be clear, there are still some optional packages that are not found, but then I didn't install them.

@myles

Thanks for making this work! :D

Works now for both C++ and dolfin demos, well this one at least:

$ python2 /usr/share/dolfin/demo/pde/poisson/python/demo_poisson.py

The working combination of packages is to use all the fenics
packages in the AUR (these are now up to date) and use viper-bzr
instead of viper.

dolfin-bzr works fine now dolfin-bzr (http://aur.archlinux.org/packages.php?ID=58971)

PARMETIS: for it to find parmetis, both metis and parmetis need to be installed

SLEPC: this works fine for me: it is found and the test passes. Maybe it is because the exports are in
/etc/profile.d/{slepc,petsc}.sh and they are only sourced when you login
MTL4: I haven't installed this yet, something about a secure certificate...
UMFPACK: The umfpack one works for me fine and the tests run.
PASTIX: N/A
SCOTCH: This is not found, although it is installed with petsc and from AUR.
PARMETIS: This is not found, although it is installed with petsc and from AUR. Did you have to set an environment variable?

For scotch and parmetis maybe dolfin needs to look harder.

1 python examples didn't work for me either for different reasons. For example, demo/pde/poisson/python/

File "/usr/lib/python2.7/site-packages/viper/viper_dolfin.py", line 134, in plot_genericfunction
data.compute_vertex_values(self.x, self.mesh)
TypeError: GenericFunction_compute_vertex_values expected 2 arguments, got 3

different examples give different errors, but not import error. However, it seems this runs c++ examples successfully.


2 Another optional package issue: during cmake CMakeLists.txt,

...
-- The following optional packages could not be found:
-- ---------------------------------------------------
-- (**) SLEPC
-- (**) MTL4
-- (**) UMFPACK
-- (**) PASTIX
-- (**) SCOTCH
...

SLEPC: We should do "export SCOTCH_DIR=/usr/petsc/arch-linux2-cxx-opt/ ", but it still says "-- SLEPc test failed".
MTL4: This is in AUR and I had it. I don't know why it couldn't find it.
UMFPACK: This is offered by either umfpack or suitesparse. I don't know why it couldn't find it.
PASTIX: This is not in AUR
SCOTCH: This is in AUR, or there is petsc downloaded version. If you wish to use the latter one, "export SCOTCH_DIR=/usr/petsc/arch-linux2-cxx-opt/" solves the problem.

This builds but there are some missing python imports (common.py,la.py...) on trying to run a demo and it is not a PYTHONPATH problem. Maybe I will find the answer soon but any help appreciated.

Sorry but I can't get this to work anymore, the build fails at 17% http://pastebin.com/sXcfNpgF . I think it is something to do with the version of CGAL, if I try to downgrade it then it wants an older version of Boost - looks like a can of worms.

So, I have submitted the package dolfin-bzr (http://aur.archlinux.org/packages.php?ID=58971), which builds fine, but there are some missing python imports.
Myles

Has a hard time finding dependencies also installed through AUR: e.g. PETSc
I had to modify src/dolfin-1.0.0/cmake/module/FindPETSc.cmake to even pick up petscconf.h
-- Checking for package 'PETSc'
-- PETSC_DIR is /usr/petsc
-- PETSC_ARCH is arch-linux2-cxx-opt
-- Found petscconf.h
-- Include directory /usr/include/include does not exist
-- PETSc test failed
-- PETSc could not be found. Be sure to set PETSC_DIR and PETSC_ARCH. (missing: PETSC_TEST_RUNS)

TEST_RUNS is defined in /usr/petsc/arch-linux2-cxx-opt/conf/petscvariables

Anybody have luck with this going through automatically?

Package broken: the source was relocated to:
http://launchpad.net/dolfin/1.0.x/0.9.11/+download/dolfin-0.9.11.tar.gz

Changing the path to the source is sufficient, MD5 stays the same.

New version 1.0beta is out!
Anyway I must report the very same error as lecio

Just two things:

1) Installing dolfin from AUR and trying to import the relative module in python let to the following error:

The file "cmake/modules/FindArmadillo.cmake" uses a deprecated method "rand". Find/replace the four occurences to the new method "randu" and it detects armadillo, and compiles.

Should armadillo be a required dependency?

makepkg aborts with:

CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:91 (MESSAGE):

myles, could you please update the PKGBUILD to work with ver.0.9.9? The build system has switched from scons to cmake, and as Radfahrer pointed out,
the python dependencies of your packages need to be changed to refer to python2 explicitly.

new verion is out and python dependency has to be changed to python2
