First, thanks for the hard work of the aurthors in the last year.
I am using the new version 5.0.0.
The code still has some problem.
After complilation, running ./ng/netgen gives
Error in Tcl-Script:
result = invalid command name "Ng_STLDoctor"
This is due to lack of subroutines Ng_STLDoctor and Ng_SetVisParameters
in file ./ng/ngpkg.cpp.
