Building mylittlengsolve error

General
1

Dear all,

I have a working version of ngsolve installed from source on OSX Ventura (and Apple M1). I followed Apple Silicon - #6 by matthiash for the build I am following the tutorial NGSolve Basics — NGS-Py 6.2.2305 documentation to build mylittlengsolve. When running the command “make -j” I get the following error message:

**/Users/alesscon/mylittlengsolve/1_Basic/myngspy.cpp:40:30:** **error:** **expected class name**

class NumProcPyDemo : public NumProc

Do you please have any advice on how to solve it?
Thanks a lot,

I see, we have removed NumProcs recently from the NGSolve core code,
but they were still in MyLittleNGSolve

Thank you for the report, it is now fixed,
