Mac build problem

Hi,

I just tried to install NGSolve from the sources on my Mac (MacOS 14.5) in the same manner I have always done. Unfortunately this failed:

[ 29%] Building CXX object fem/CMakeFiles/ngfem.dir/hcurlfe.cpp.o /Applications/NGSolve/src-ngs/fem/hcurlfe.cpp:463:7: error: use of undeclared identifier 'testout' (*testout) << "a = " << a << endl; ^ /Applications/NGSolve/src-ngs/fem/hcurlfe.cpp:481:8: error: use of undeclared identifier 'testout' (*testout) << "breakdown in householder, a = " << a << endl; ^ /Applications/NGSolve/src-ngs/fem/hcurlfe.cpp:650:7: error: use of undeclared identifier 'testout' (*testout) << " Compute Gradient Matrix H1-HCurl Low order FEs " << endl ^ /Applications/NGSolve/src-ngs/fem/hcurlfe.cpp:2684:7: error: use of undeclared identifier 'testout' (*testout) << "fiphij3 = " << endl << fiphij3 << endl; ^ 4 errors generated. make[5]: *** [fem/CMakeFiles/ngfem.dir/hcurlfe.cpp.o] Error 1 make[5]: *** Waiting for unfinished jobs.... make[4]: *** [fem/CMakeFiles/ngfem.dir/all] Error 2 make[3]: *** [all] Error 2 make[2]: *** [dependencies/Stamp/ngsolve/ngsolve-build] Error 2 make[1]: *** [CMakeFiles/ngsolve.dir/all] Error 2 make: *** [all] Error 2
I have attached the full terminal Output.

The motivation behind a clean install, was because the Netgen GUI crashed on startup, see
https://ngsolve.org/media/kunena/attachments/830/netgen_gui_fail.txt. (The python interface was working.)

Can anyone help with these issues?

Best wishes,
Henry

Hi Henry,

testout was moved to Netgen, so I guess you didn’t update the submodule before building NGSolve:

# in source dir of NGSolve: git submodule update --init --recursive

The second issue is nagging us since the last MacOS update. In order to get Netgen running, you need to download an old SDK (Version 10.9 from here: https://github.com/phracker/MacOSX-SDKs​) and point CMake to it at configure time:

export MACOSX_DEPLOYMENT_TARGET=10.9 cmake -DCMAKE_OSX_SYSROOT=path_to_your_sdk ...

Best,
Matthias

Hello Matthias,

thank you for your response! I looked into the terminal output and I did update the submodules. I also tried to build it with the latest sources and the SDK 10.9 but had the same issue with testout.

Best wishes,
Henry

Now I see the issue: You have another installation of Netgen/NGSolve in /Applications/Netgen.app

The build erroneously uses this incompatible Netgen version to build NGSolve.
I will see that this gets fixed, in the meantime you have to (re)move the other version at /Applications/Netgen.app before building you own one.

Best,
Matthias

Thank you Matthias! This has worked now!

It hadn’t occurred to me that the Netgen.app would be a problem, as I did not add it to my Path variable.

Best wishes,
Henry
