Hello everyone,
as all the previous posters i have trouble compiling foamyMesh. I'm using OpenFoam 5 in an Ubuntu 16.04 installation based on the Windows Subsystem for Linux.
The error from the foamyMesh compilation is

lnInclude/CGALTriangulation3DKernel.H:36:43: fatal error: CGAL/Delaunay_triangulation_3.h: No such file or directory

This is the same problem the OP faced and i went straight to compile CGAL. So i downloaded the Third-Party-5.0 archive and ./Allclean + Allwmake'd it. The comilation runs fines, besides CGAL which gives

optional component was not found

Running the ./makeCGAL command seperately yields

Using system installation of CGAL

So it seems CGAL is installed in one way or another ?!. I also tried downloading CGAL from its website and instlling it seperately, but returnung the compiling foamyMesh still ends in an error.

Can somebody identify my error and help me out?

With best regards,
Robert

Hi Robert,

Try to check whether cgal_version is set to cgal-system in OpenFOAM-5.0/etc/config.sh/CGAL file (Also check for other softwares in OpenFOAM-5.0/etc/config.sh/ folder )

Run the following command in terminal to make sure you installed cgal and other required libraries for cgal on ubuntu, and then re-compile:
sudo apt-get install libcgal-dev libcgal-demo libgmp-dev libgmp-dev libmpfr-dev

Also better to cross-check with the software to be installed for 16.04 from: http://openfoamwiki.net/index.php/In...OAM-dev/Ubuntu

Quick notes:

• Step-by-step instructions for compiling OpenFOAM 5.x with foamyHexMesh on Ubuntu 16.04 are available here: http://openfoamwiki.net/index.php/In...u#Ubuntu_16.04
• The missing system package is "libcgal-dev".

I changed cgal-system to cgal-4.11.1 and ran your apt-get line, which also installs libcgal-dev (thanks Bruno!). Finally foamyMesh compiles w/o problems.

But... that would mean that you would not use the CGAL that you then installed in Ubuntu with apt...
Well, as long as it is now built and running properly, I guess that it's not worth double-checking what happened exactly
