Re: compiling libapl for python3

[Dr . Jürgen Sauermann]

    Hi again,
      
      just tried python 3.8 and everything works just fine.
      
      The README-10-python is slightlly out of date since it says to
      copy
      the GNU APL .so file into /usr/lib/python3.4/lib-dynload/.
      This was
      apparently correct at the time of writing but now I had to copy
      into
    /usr/local/lib/python3.8/lib-dynload/.
        This may also depend on how
        python was installed. And is difficult to spot sinve both the /usr/libpython3.8
            and the /usr/local/lib/python3.8
            directories exist and if you copy to the
            wromg one then you will get a "module not found" error in
            python.
            
            Best Regards,
            Jürgen

Hi enztec,

which SVN version worked on your side? And does it still work?

I suppose that the python callling conventions for modules have changed in
the meantime, since there never was a main() function in python_apl.cc.

Best Regards,
Jürgen

Hi Jürgen

import gnu_apl

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /usr/local/lib/python3.10/lib-dynload/gnu_apl.cpython-310-x86_64-linux-gnu.so: undefined symbol: main

a gnu_apl.so from an earlier svn compile works fine - so nothing has changed at this end

thanks
