Didn't test it yet but just wanted to say thanks.
In the lines of the established culture of crediting in FreeCAD community thanks especially to you @gdo35. As without your help it wouldn't have happened.

I'll try to see if it can be of use with 5.3.1.

@ blacey I'm in need of help on netgen again
EDIT: see my reply below, it seems to require patching, I'll try that tomorrow...

Here's one of the things I tried:

I also tried --with-occ=/usr and I get the same result.
When doing make I get
Maybe this is the problem?
Any pointers would be appreciated.

Re: [Ubuntu Daily PPA] Transitioning to OCCT7, VTK7...
Just had a look at the debian packaging of netgen-4.9.13, it requires a patch to solve the occ-dir issue. Seems like this is still the case with 5.3.1.
configure-occ.patch
configure-occ.patch
Code: Select all
Change OCC include directory and the Togl lib name to Debian's.

Any pointers would be appreciated.
Thanks!
1) First, make is failing to find the OpenCascade include file BRepAlgo_AsDes.hxx. The author hardwired the include paths in the configure.ac/configure script so the nglib formula on macOS mutates the configure script because the include files are not installed into one of the author's hardwire paths. It seems you need to do the same on Linux. Perform a find to locate the header file to determine the proper include prefix.
Code: Select all
find /usr -name BRepAlgo_AsDes.hxx
2) Below is the section of the netgen configure script that you will want to examine and possibly change:
Code: Select all
if test a$occon = atrue ; then
OCCFLAGS="-DOCCGEOMETRY -I$occdir/inc -I/usr/include/opencascade"
OCCLIBS="-L$occdir/lib -lTKernel -lTKGeomBase -lTKMath -lTKG2d -lTKG3d -lTKXSBase -lTKOffset -lTKFillet -lTKShHealing -lTKMesh -lTKMeshVS -lTKTopAlgo -lTKGeomAlgo -lTKBool -lTKPrim -lTKBO -lTKIGES -lTKBRep -lTKSTEPBase -lTKSTEP -lTKSTL -lTKSTEPAttr -lTKSTEP209 -lTKXDESTEP -lTKXDEIGES -lTKXCAF -lTKLCAF -lFWOSPlugin"
3) Once you have a working configure script, you can use something like sed to edit the configure script before running configure or create a patch file for the configure and apply it before running configure.
Re: [Ubuntu Daily PPA] Transitioning to OCCT7, VTK7...
Thanks Bruce.
So I need to go back to the original unpatched configure file at least for that section because it's an undesirable change on Ubuntu.
Thanks.

No problem, thanks for updating the patch, I'll try it over the weekend.
@ HoWil and bejant
Glad you find it useful, I'm happy that the PPA is now on par with OS X and Win regarding OCC, now I hope we can update netgen and vtk.

Re: [Ubuntu Daily PPA] Transitioning to OCCT7, VTK7...
Compiling netgen is proving a pain...
I had to make a change in the configure file:
The last library referenced, "FWOSPlugin", was removed from Open CASCADE 7.0.0. bernd hasn't removed it from his patched netgen repo, I'm surprised it manages to compile!
So after this slight change it seems to build fine with make, but afterwards the make install step is where I trip. Actually I don't want to do make install because I have no idea if I'll be able to remove it afterwards. So I used checkinstall instead, because it creates a basic .deb package I can easily uninstall.
But no matter what I do, it does not install all the required files. When I try to configure FreeCAD with BUILD_FEM_NETGEN enabled, I get bunches of errors about missing files. I also have to manually set a lot of paths for netgen which is pain, because I'm not even sure these paths are correct.
After configure...
I need to go over these 19 pages of replies again!
