Hi all

I am using OpenFoam extend 3.2. The first time I noted that something was wrong with my OpenFoam installation was this error message from running a test case:

--> FOAM Warning : 
    From function dlLibraryTable::open(const fileName& functionLibName)
    in file db/dlLibraryTable/dlLibraryTable.C at line 124
    could not load libtriSurface.so: cannot open shared object file: No such file or directory

I traced this back to an error during the installation of swak4Foam:

...
Swak version is 0.4.0
Bison is version 2.7.12-4996
Flex is version 2.5.35 (Minor version: 35)
OpenFOAM-version: Major 3 Minor 2 Patch 0 (-1 == x / 0) Fork: extend
...
Making dependency list for source file ExpressionResult/DelayedExpressionResult.C
could not open file string.H for source file helpers/exprString.C
...

The files string.H and time.H have apparently moved compared to the previous OpenFoam version? I thought this was related to this thread:

https://sourceforge.net/p/openfoam-e...ndrelease/281/

Even after updating the swak4foam version to 0.4.0, or git static checking to the original commit

https://github.com/Unofficial-Extend...6b8810e1afa4ee,

still no luck. The error persists.
According to

http://www.cfd-online.com/Forums/ope...risurface.html

this is because triSurface.so is moved to meshTools? The solution proposed there, creating a symbolic link in the $FOAM_SRC folder doesn't seem to work for me.

Anyone came across this before and has a solution?

Thanks in advance!

Greetings PieterjanR,

There is something very strange going on with your installation, because I've re-tested just now with foam-extend 3.2 (the official name and version of this fork) and with swak4Foam 0.4.0 and I had absolutely no problems building it.

Hold on...

No no no... that message "could not open file" when building is explained here: http://openfoamwiki.net/index.php/In...e_or_directory - essentially it can be ignored, since that is not the problem.

The message about not being able to load "libtriSurface.so" is not a problem with swak4Foam, it's because foam-extend 3.2 itself no longer has that library.

The solution is to simply remove "libtriSurface.so" from the "libs" list in "system/controlDict".

Best regards,
Bruno

Indeed, this was surprisingly simple

I'll try to run a clean install of swak4foam and see if the error is gone now.
