Compilation error in MacOS 14.12

[nayanbera]

While trying to compile PyDevice in MacOS 14.12 with EPICS 7.0.7 and Python 3, I got the following error:

Although I got rid of the errors mentioned above either by commenting on lines (345, 346) or lines (351, 352) of pywrapper.cpp, the compilation ended with linking error:
