Hello all,

I'm running OpenFOAM-v2406 on WSL/Ubuntu.
I installed the precompiled openfoam2406-default package.

I need to use ccmToFoam, which requires to be compiled after building the libccmio library, but I fail to do so.

EDIT: I solved my issue, so I'm going to turn this post into a tutorial.

Here is the process:

1. Start a WSL session. In order to have write permission in the default OpenFOAM installation directory, you will need to start a shell with root privilege: sudo -s
2. Load the OpenFOAM environment: source /usr/lib/openfoam/openfoam2406/etc/bashrc
3. Move to the OpenFOAM install directory: foam
4. Download the ThirdParty-v2406.tgz archive: wget https://dl.openfoam.com/source/v2406...arty-v2406.tgz
5. Unpack the archive: tar -xzf ThirdParty-v2406.tgz
6. Rename the extracted directory: rm ThirdParty && mv ThirdParty-v2406 ThirdParty
7. Move to ThirdParty/sources directory and download the libccmio-2.6.1.tar.gz archive: cd ThirdParty/sources/ && wget https://sourceforge.net/projects/foa...o-2.6.1.tar.gz
8. Unpack the archive: tar -xzf libccmio-2.6.1.tar.gz
9. Get back to the ThirdParty directory and reload the OpenFOAM environment: cd .. && source /usr/lib/openfoam/openfoam2406/etc/bashrc
10. Compile the libccmio library: ./makeCCMIO
11. Move to: cd $FOAM_SRC/conversion/ccm
12. Build the libccm library: ./Allwmake
13. Move to: cd $FOAM_UTILITIES/mesh/conversion/ccm/
14. Build the ccm utilities: ./Allwmake
15. All done, exit the root shell and reload the OpenFOAM environment: exit && source /usr/lib/openfoam/openfoam2406/etc/bashrc

Here you go, you should now be able to use ccmToFoam and foamToCcm

If anyone more competent than me knows a better way to do this, let me know!
