BilinearForm incorrect?

Hey Matthias,

Yes I am following this guide. The problem is (for both machines) at step ngsolve.org/docu/latest/install/installmacnative.html#building

Some of the output I am getting is collected in this gist: gist.github.com/Jannertje/ac7540742c23eebc2961eca566ef95b0
[please read `shell_output` first, and the rest afterwards.]

I tried running `make` with both Tcl and Tcl/Tk installed and uninstalled. Do you have any idea?

Hi Jan,

A first guess: Did you remove the dmg bundle before starting the configuration?

Ha good catch! I certainly did not.

This got me a little further, it is now crashing at `project_tk` rather than `project_tcl`: gist.github.com/Jannertje/b0e9b5e4be0cb52f0166f7f3ddd51918
when I `brew uninstall tcl-tk` and rerun, I get a different error -- see `WITH_TK*` and `WITHOUT_TK*` in the gist linked above.

That's interesting, NGSolve should build and link it's own version of Tcl/Tk, so brew is not necessary at all.
Try to wipe /Applications/Netgen.app and your build directory completely and run cmake from scratch.

Hey Matthias,

Thanks a lot -- I got it working by updating my clang to 10.0 for c++17 (required by -i think- pybind11). I now have my own build from source !!
