Re: [Bug-apl] Python Interface

[Dr . Jürgen Sauermann]

Hi, I haven't tried Python 2.7 but it may work. I followed the instructions in https://docs.python.org/3.3/c-api I personally find Python 2.7 somewhat odd, so I never considered it. According to ./configure  --help: ...   --with-python           enable to build python extension lib_gnu_apl.so ... so --with-python is the correct approach. Regarding the python version, you can either: change line 184 in src/Makefile.am: lib_gnu_apl_la_CXXFLAGS += -I/usr/include/python3.4m to reflect your Python version and then autoreconf and ./configure --with-python again, or something like: CXX_FLAGS="-I/usr/include/python3.4m" ./configure --with-python Best Regards, Jürgen On 6/17/19 6:22 AM, Christian Robert wrote: If I configure with: --with-libpython_apl it says: configure: WARNING: unrecognized options: --with-libpython_apl If I configure with: --with-python it fail in #include <Python.h>   (no such file or directory) probably because of hard coded "-I/usr/include/python3.4m" which does not exist on my system. this is because it try to compile with python3.4m  but on my system (fedora30) the installed pythons are: [xtian@FC-30:/home/xtian/gnuapl] $ python -V Python 2.7.16 and [xtian@FC-30:/home/xtian/gnuapl] $ python3 -V Python 3.7.3 You can probably invoke python3-config as in: [xtian@FC-30:/home/xtian/gnuapl] $ python3-config --help Usage: /usr/bin/python3.7m-x86_64-config --prefix|--exec-prefix|--includes|--libs|--cflags|--ldflags|--extension-suffix|--help|--abiflags|--configdir [xtian@FC-30:/home/xtian/gnuapl] $ python3-config --includes -I/usr/include/python3.7m -I/usr/include/python3.7m [xtian@FC-30:/home/xtian/gnuapl] $ python3-config --libs -lpython3.7m -lcrypt -lpthread -ldl  -lutil -lm to figure-out where are the includes dirs and may be other dirs. I suppose this interface is NOT intended for python2 at all, and it's fine with me. Xtian.

With that interface you can execute APL code, create APL defined functions, etc.  from Python. Similar to *libapl* for C/C++ or to the Erlang interface.
