Dear all,

I've installed OpenFoam v18.06 under Ubuntu 18.04 (Linux-Subsystem for Win10).

I tried to set the working environment by

echo "source /opt/OpenFOAM/OpenFOAM-v1806/etc/bashrc" >> ~/.bashrc
source $HOME/.bashrc

and received an error message

-bash: eval: line 38: syntax error near unexpected token `('
-bash: eval: line 38: `PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/mnt/c/Program:Files/WindowsApps/CanonicalGroupLimited.Ubuntu18.04onWindows_1804.2018.817.0_x64__79rhkp1fndgsc:Files:(x86)/Common:Files/Oracle/Java/javapath_target_230390484:(x86)/Business:Objects/Common/3.5/bin/NOTES:(x86)/NVIDIA:Corporation/PhysX/Common:/mnt/c/ProgramData/Oracle/Java/javapath:Files/Common:Files/microsoft:shared/Windows:Live:(x86)/Silverfrost/FTN95:Express:/mnt/c/Windows/System32:/mnt/c/Windows:/mnt/c/Windows/System32/wbem:/mnt/c/Windows/System32/WindowsPowerShell/v1.0:/mnt/c/dislin/win:(x86)/MiKTeX:2.9/miktex/bin:(x86)/Windows:Live/Shared:(x86)/Calibre2:(x86)/GNU/GnuPG/pub:/mnt/c/Windows/System32/OpenSSH:Files/ngsolve-v6.2.1805/bin:/mnt/c/Users/Christoph/AppData/Local/Programs/Python/Python36/Scripts:/mnt/c/Users/Christoph/AppData/Local/Programs/Python/Python36:/mnt/c/Users/Christoph/AppData/Local/Microsoft/WindowsApps:/snap/bin'

Despite the error the installation seems to work so far.
But nevertheless I would like to understand and solve this problem.
So any hints are welcome.

Thanks and best regards
Christoph

Quick answers:

1. The error messages occur because the PATH environment variable is inherited from Windows into Ubuntu Bash.
2. This carries with it paths such as "C:\Program Files (x86)" which OpenFOAM usually is allergic to it.
3. One solution is to upgrade to OpenFOAM-v1812, which has this bug already solved.
4. Another solution is to reset the PATH variable to something more... normal by Ubuntu's standard... for example, edit the file "~/.bashrc" in Ubuntu and add the following line before sourcing OpenfOAM's "etc/bashrc":
   

   export PATH=$HOME/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Thanks for your quick response.

It works with upgrade to v18.12.

This solves the problem but permanently deletes other paths, including the Windows one. Before sourcing, I used the following to back up my paths before sourcing "/opt/openfoam11/etc/bashrc". Then, I appended them at the end.

# For OpenFOAM
# workaround of alien paths issues from windows in WSL 
# store temporary path
export tmp_PATH=$(echo $PATH | sed 's|^/usr/local/bin:||;s|:/usr/local/bin:|:|g')
export tmp_PATH=$(echo $tmp_PATH | sed 's|^/usr/bin:||;s|:/usr/bin:|:|g')
export tmp_PATH=$(echo $tmp_PATH | sed 's|^/bin:||;s|:/bin:|:|g')
export tmp_PATH=$(echo $tmp_PATH | sed 's|^/usr/sbin:||;s|:/usr/sbin:|:|g')
export tmp_PATH=$(echo $tmp_PATH | sed 's|^/sbin:||;s|:/sbin:|:|g')
# reset PATH to basic Linux
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
# source OpenFOAM environment
source /opt/openfoam11/etc/bashrc
# add paths from tmp_PATH
export PATH="$PATH:$tmp_PATH"
