netgen 6.2, cmake options for compiling for FreeCAD

[bernd]

When compiling netgen 5.3 with configure one had to set some parameters.

Netgen 6.3 uses cmake to set up build. Does someone know which parameters to set for building netgen for FreeCAD on debian.

EDIT: it is about Netgen 6.2, Version 6.3 is not yet released

Do you mean 6.2? It doesn't seem 6.3 is released yet from what I can find. Anyway, 6.2 is already in Debian Testing/Unstable so you should just be able to install it (https://tracker.debian.org/pkg/netgen). The rules for the package build here show the flags used: https://salsa.debian.org/science-team/n ... bian/rules

I only need netgen to build FreeCAD with. This never worked with the debian packages. One had to build netgen and to copy include files.

Does it mean on buster we can use the debian packages? are they build with opencascade?

Yes, it should be possible to do that as they are built with OCCT 7.3.0 but I've never tried using it in much depth since it seemed disabled in the FEM workbench.

sure, it is disabled in FEM and Mesh wb if FreeCAD is not build with netgen. As soon as FreeCAD is build with netgen the mesher is available in FEM an in Mesh WB.

I lately switched to Buster and Py3 and Qt5 and just realised no netgen anymore for my in FEM wb ...

yes. I changed the topic title in this regard

with this I got it compiled ... The strange thing is netgen cmake would like to have write permissions to the install dir I never had this on cmake or make run ... I just made them with sudo. I may try later if it would work without too.

Code: Select all

git clone https://github.com/looooo/netgen netgen
mkdir build
cd build
sudo cmake  \
-DUSE_PYTHON=False \
-DUSE_GUI=False \
-DUSE_OCC=True \
-DOCC_INCLUDE_DIR=/usr/include/occt \
../netgen

sudo make -j4
sudo make install

ok now FreeCAD with netgen ...

I guess this is because of the "superbuild". There is an option to disable "superbuild":
