@aslakstubsgaard I have fixed the errors but I'm not sure the patches are right. Please help me to check them.

is it just me or is this package still missing an upgrade to work with the gcc 8.1 release from back in may?

Something does not work right:

$ ofoam
-bash: .: /opt/OpenFOAM: is a directory
-bash: /opt/OpenFOAM: Is a directory
-bash: _foamSource: command not found
-bash: _foamEval: command not found
-bash: /opt/OpenFOAM: Is a directory

-bash: /opt/OpenFOAM: Is a directory
-bash: /opt/OpenFOAM: Is a directory
-bash: .: /opt/OpenFOAM: is a directory
-bash: .: /opt/OpenFOAM: is a directory

The bashrc sets $FOAM_INST_DIR to something invalid:

$ echo $FOAM_INST_DIR 
/opt/OpenFOAM ~ /opt/OpenFOAM

@ddcampayo I find

$ pacman -Fl openfoam | grep bin snappyHexMesh
openfoam opt/OpenFOAM/OpenFOAM-5.0/platforms/linux64GccDPInt32Opt/bin/snappyHexMesh
openfoam opt/OpenFOAM/OpenFOAM-5.0/platforms/linux64GccDPInt32Opt/lib/libsnappyHexMesh.so

in my pre-built package. Are these what you need?

PS. You can download my pre-built package from https://mirrors.tuna.tsinghua.edu.cn/arch4edu/

Installs ok, but some of the utilities are missing. E.g. snappyHexMesh. If I got to dir /applications/utilities/mesh/generation, then run (as root) ./Allwmake , blockMesh, extrude, and extrude2DMesh, compile. But not snappyHexMesh. That one spits:

Install appears to run perfectly, no errors.

But the ofoam alias doesn't appear to work (it doesn't exist).

Also, if I manually run 'source /opt/OpenFOAM/OpenFOAM-5.0/etc/bashrc' it simply returns to command line. It runs something as it takes a second before it returns, but no messages, warnings or errors.

Not sure how to diagnose this.

The problem ist that the new tar-file is not fetched because of the file naming, which omits the pkgrel-number. Version 5.0.1 and 5.0.2 are having the same filename (version-5.0.tar.gz). Remedy: $ cd $HOME/.cache/pacaur/openfoam $ mv version-5.0.tar.gz version-5.0.tar.gz.bak

Same problem here. The most recent git commit (Fri Sep 15 16:26:13 2017 +0800) updated the md5sum, which didn't help.
