I'm running OpenSUSE 42.1 Leap, and am trying to install various versions of OpenFOAM (2.4.x - 4.x) onto my system. I first installed 2.4.x without any issue, but then tried to run an example parallel case using the the scotch decomposition method - that ended up failing because OF24x wasn't installed using scotch. I checked that I had scotch installed on my system, as well as the development headers - that wasn't the problem.

I cleaned by build directory and tried reinstalling OF24x again and noticed I was getting errors because OF couldn't find the scotch headers (scotch.h and ptscotch.h) I've tried editing the etc/config/scotch.sh file (similar to how the instructions on the wiki say for CGAL), but that didn't work and the build failed making a number of libraries.

In the end I found out that OpenFOAM looks for scotch in the ThirdParty directory by default instead of the system, and since current ThirdParty 2.4.x git repo doesn't contain it, I had to copy it over from the ThirdParty 2.4.0 tgz folder. This means that for every OpenFOAM install, I need to have a copy of the scotch source in each respective ThirdParty directory, which doesn't seem ideal.

Questions:
  1. Why is the scotch source directory not included in the ThirdParty 2.4.x repo?
  2. How do you allow OpenFOAM to access your system's version of scotch?

Scotch's source code was only added on the 30th of May 2016 after it was reached the conclusion that it was best to add ParaView to OpenFOAM's ThirdParty git repositories, as reported here: http://bugs.openfoam.org/view.php?id=2098 - Scotch was also added as well, so that this way we could do a source code snapshot directly from the ThirdParty repository and have the essential source code ready to build OpenFOAM (without "foamy*Mesh").

I haven't had the time to do a complete test, but the following should do the trick:
  1. The science repo must be in the repository list, so as root the following command is needed (e.g. for 42.1):
    Code:
    zypper addrepo -f -n science http://download.opensuse.org/repositories/science/openSUSE_Leap_42.1/ science
  2. Then install Scotch and PTScotch:
    Code:
    zypper install scotch ptscotch-openmpi libptscotch0-openmpi libptscotch-openmpi-devel libscotch-devel
  3. Next use the following lines in the scotch configuration file "etc/config/scotch.sh":
    Code:
    export SCOTCH_VERSION=scotch_6.0.4
    export SCOTCH_ARCH_PATH=/usr/lib64/mpi/gcc/openmpi
    export SCOTCH_ROOT=/usr/lib64/mpi/gcc/openmpi
  4. Next we need to fix a few bugs, by running:
    Code:
    cd $WM_PROJECT_DIR
    find src applications -name options | xargs grep SCOTCH_ROOT -sl | xargs sed -i -e 's=SCOTCH_ROOT)/lib=SCOTCH_ROOT)/lib64='
  5. Now try building OpenFOAM.

Worked for me, too....

OpenSuse Leap 15, OpenFoam v1806

Steps (like wyldckat said):

Added repository Science (Leap 15.0):
http ://download.opensuse.org/repositories/science/openSUSE_Leap_15.0

http://download.opensuse.org/reposit...SUSE_Leap_15.0

Followed step 2 & 3 of wyldckat (OpenFOAM-v1806/etc/config/scotch.sh)

Step 4 was not necessary for me ...

Finally:
cd $FOAM_SRC/parallel/decompose
./Allwmake

It is still a work in progress, but you can also use openfoam1806 from the same science repo - it uses system libs for everything and does the configuration for you too. Recently updated their version of scotch to 6.0.6 and also put in a paraview-devel (version 5.6.0) as well.
The OpenFOAM RPM is currently built without the paraview dependency, but the native reader is probably all you need.
For 1812 we will also be able to build with a system paraview, but the config is not as comfortable. Probably have openfoam1812 RPM without paraview as well - don't think that this is the right place for the paraview bit.

Note that the RPM namings have the major version as part of the name, since we'd like people to be able to install different versions side by side. The openfoam-selector is like the mpi-selector and provides a simple means of setting the environment.

Any feedback on gitlab please, I don't read the forums very regularly.

Thanks! Worked for me as well.

In Step 3, I didn't change the scotch version environment variable and Step 4 wasn't necessary for me. I'm using OpenSUSE 15.0 and OpenFOAM 6.

Just incase you are still stuck with the issue.



Error I got when compiling OpenFOAM-6
Code:
scotchDecomp.C:36:20: fatal error: scotch.h: No such file or directory
 #include "scotch.h"
                    ^
compilation terminated.
make: *** [/home/alpatil/OpenFOAM/OpenFOAM-6/platforms/linux64GccDPInt32Opt/src/parallel/decompose/scotchDecomp/scotchDecomp.o] Error 1

The compilation was trying to look for

"using SCOTCH_ARCH_PATH=/home/alpatil/OpenFOAM/ThirdParty-6/platforms/linux64GccDPInt32/scotch_6.0.3"


As there was no ThirdPart-6 directory the compilation terminated.



I extracted the Thirdparty-6-version-6 and renamed it to ThirdParty-6 and everything seems to be working now.



Not sure if this is the issue with everyone else. Hope it helps!


Cheers!

I'm trying to install OpenFOAM 5.x on Centos8 and would like to use a system version of scotch, however following the fix outlined above, I still get an error:


Code:

Build Scotch decomposition library scotch_6.0.5
    /usr/include/openmpi-x86_64/
+ cd scotch_6.0.5/src
/home/dustiest/OpenFOAM/ThirdParty-5.x/Allwmake: line 204: cd: scotch_6.0.5/src: No such file or directory
+ exit 1
Does anyone have any ideas as to how to get ./Allwmake to look for system scotch libraries?
