Dear Foamers,

I am trying to install OpenFoam 4.0 on my universities clusters on which i do not have admin rights. Gcc(5.4.0) is installed on the system so i do not have to compile that myself.
CGAL is not installed but since I do not need foamyHexMesh this should not be a problem.

Now i have been following this install guide: https://openfoamwiki.net/index.php/I...CentOS_SL_RHEL

Acording to wyldckat in this thread http://www.cfd-online.com/Forums/ope...s-sl-rhel.html I need to make a couple of adjustments to the standard guide

step 7:

source $HOME/OpenFOAM/OpenFOAM-4.0/etc/bashrc WM_LABEL_SIZE=64

in stead of

source $HOME/OpenFOAM/OpenFOAM-4.0/etc/bashrc WM_LABEL_SIZE=64 WM_COMPILER_TYPE=ThirdParty FOAMY_HEX_MESH=yes

skip steps #10 11 and #12.

Since paraview is already installed I have skipped steps #13 and #14 as well.

If I run allwmake with this configuration I get an error that gmp cannot be found

-- Could NOT find GMP (missing:  GMP_LIBRARIES GMP_INCLUDE_DIR) 
CMake Error at cmake/modules/CGAL_SetupDependencies.cmake:66 (message):

I have also tried to comment out the section relating to CGAL in the allwmake script in the third-party directory. This gives the following error:

I assume this boost error is related to the not compiling of GCAL. Any pointers on what i am forgetting?

Hi,

First error is caused by missing GMP (http://gmplib.org), since you have skipped step 10 from the guide, you have no GMP. So compile it manually. Also, since you have skipped step 10, you miss mpfr library (http://www.mpfr.org), which is required by CGAL.

Second error is causes by missing boost, guess it should be built during CGAL installation with makeCGAL script.

HI alexeym,

Thanks for your reply. From what I understand, Openfoam only needs CGAL (and therefore boost and gmp and mpfr ) for foamyhexmesh. Since I don't need foamyhexmesh and only the solvers can i compile without needing CGAL and the other lib's?

[alexeym]

Well,

$ pwd
$HOME/OpenFOAM/OpenFOAM-4.0
$ cd src
$ $ grep -rl CGAL *
renumber/Allwmake
$ cd ../applications/
$ grep -rl CGAL *
utilities/mesh/generation/Allwmake
...
utilities/mesh/generation/foamyMesh/...
...

So, yes; you need CGAL for foamy*Mesh apps; and boost for SloanRenumber library.

To skip foamy*Mesh build you just need to unset FOAMY_HEX_MESH environment variable (export -n FOAMY_HEX_MESH or comment out 'export FOAMY_HEX_MESH=yes' line in etc/bashrc).

To skip SloanRenumber build you need to unset BOOST_ARCH_PATH and set boost_version variable to something not equal to boost-system. This can be achieved by commenting out whole etc/config.sh/CGAL file. Or comment out 'wmake $targetType SloanRenumber' in src/renumber/Allwmake file.

Hi alexeym,

Thanks heaps, commenting out wmake $targetType SloanRenumber' did the trick. It is all running smoothly now.

Cheers
