Hi,
thanks, good to know. My personal feeling is that Python
configuration is an
unportable mess. If I run python3-config, then I get:
pyenv:
python3-config: command not found
The `python3-config' command exists in these Python
versions:
3.6.4
No idea what this means or why this is so.
For that reason I prefer explicit settings rather than tools that
"help" me
getting things right.
Best Regards,
Jürgen

I made
it work but only with some works
Makefile.am from:
lib_gnu_apl_la_CXXFLAGS += -I/usr/include/python3.4m
to:
lib_gnu_apl_la_CXXFLAGS += `python3-config --includes`
then run: "autoreconf"
./configure --with-python
make -j4
sudo make install
then had to run as root:
cd /usr/lib64/python3.7/lib-dynload/
ln -f /usr/local/lib/apl/lib_gnu_apl.so
gnu_apl.cpython-37m-x86_64-linux-gnu.so
*Note* the different target name. I made a hard link rather than a
copy (cp), matter of tastes.
then it works!

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

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.

Hi,
in following a suggestion by Kumar Ramanathan, I have
created a Python interface for GNU APL.
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.
See *README-10-python* for details.
*SVN 1167*.
