[looooo]

Is there an existing issue for this?

Problem description

Tested on conda-version (osx-arm). Something must have changed so that the netgen-mesher is not enabled anymore in version 1.0.0. I get this error message when trying to run netgen: FEMMeshNetgen: The FEM module is built without NETGEN support. Meshing will not work!!!

The conda-packaging didn't change, so normally netgen should work.

@marioalexis84 @oursland FYI

Could you check if the cmake entry BUILD_FEM_NETGEN=ON is defined?

[looooo]

it is but the build logs show: -- NETGEN: not enabled

Could you check if the cmake entry BUILD_FEM_NETGEN=ON is defined?

I am sorry, I checked the wrong files, somehow it was indeed disabled. Blame on me!!

[marioalexis84]

There were no recent changes to FindNETGEN.cmake. Do you have any reference commit for which Netgen is found on your current system?

[bofdahof]

The message in the build log is misleading as it is conditional on NETGEN_FOUND, so should say "not found" rather than "not enabled" or a further condition added based on build flag to correctly report when not enabled.

Would it make sense to add a value entry in the report for BUILD_FEM_NETGEN (currently only BUILD_FEM)?

[looooo]

I tested now on different platforms. Netgen works for all the qt5 builds. For the qt6-builds it's not working. One difference I see in the build logs is the following:

qt5 reports this:

-- Could NOT find Netgen (missing: Netgen_DIR)
-- Cannot find NETGEN header files.
-- Cannot find NETGEN library.

qt6 reports only:

-- NETGEN: not enabled

[looooo]

Sorry for the rumours, somewhere in the commit history during updating to qt6 I had disabled BUILD_FEM_NETGEN. So this should be fixed. Thanks for the help.

Does this also cause Netgen to not be selectable in the Mesh Workbench, or is that a separate issue?
