Hi foamers,
I want to convert a .ccm mesh file by STAR-CCM+ to OpenFOAM. In the OpenFOAM-v1912, there are two files in $FOAM_APP/utilities/mesh/conversion/ccm, ccmToFoam and foamToCcm, respectively. But when I want to execute the Allwmake file in ccmToFoam, there is an error "==> skip optional ccm conversion components (no libccm.so)".
Need your help and wish your reply.

Same problem with openFOAM 2112. I've downloaded the library libccmio-2.6.1 and placed in which seams to be the required folder

/usr/lib/openfoam/openfoam2112/platforms/linux64GccDPInt32Opt/lib/libccm/

since the Allwmake script is loocking for the lib at

$FOAM_LIBBIN/libccm

but the Allwmake is still unable to find it.

please read this thread, the solution of Mathieu works to me, I hope it also works for you.
I think the problem maybe there are some special settings in OpenFOAM compile which would relocate the libccm. But I don't know the details.

I just have revisited the procedure to compile CCM tools for OpenFOAM. In my case, I started with a fully compiled OpenFOAM-v1706, but I guess these steps should also work for a fresh install (not compiled). First, you'll need the libccmio-2.6.1 directory to be located in the ThirdParty-v1706 directory. See the ThirdParty-v1706/BUILD.md file for instructions on how to obtain it and check usage conditions since it is a proprietary package. Then:

cd $WM_THIRD_PARTY_DIR
./makeCCMIO libso
./makeCCMIO lib
foam
./Allwmake


Afterwards, for the legacy converter (if you need it):

app
cd utilities/mesh/conversion/Optional/
./Allwmake


Hope this helps.

in the OpenFOAM compilation process, I find the following information, I don't know whether it is helpful.
