Dislin compilation

[Gaubitzer Erwin]

Hi everybody

I want to recompile the DISLIN graphics module for Python under Linux, because
I think it is one of the best graphics libraries at present.
The included module was for version 2.0 and I want it for 2.2 or maybe 2.3.
The problem is, that I use the small make_py script which only
calls the gcc compiler

CC="gcc -fPIC -c -O"
PYTH_INC="/usr/local/include/python2.0"
PYTH_CONF="/usr/local/lib/python2.0/config"
gcc -shared -Wl,-soname,dislinmodule.so -o dislinmodule.so *.o \
-L$DISLIN -ldislnc
but I think many variables arent configured,
so a long list of errors follows (I copied the first few lines to
the end)

I dont have experience with makefiles and so I want to ask what I
have to do in a short way.

Thanks in advance

Erwin

My system:
SuSE Linux 8.1 on an AMD-machine

You have to edit the file 'make_py' and define the variables PYTH_INC and
PYTH_CONF with
corresponding directories of your Python version (i.e.
PYTH_INC=/"usr/local/include/python2.3"
or PYTH_INC="/usr/include/python2.3").
The environment variable DISLIN is used to locate the DISLIN library. You can
define it outside
of the make_py script with the installation directory of DISLIN (i.e. export
DISLIN=/usr/local/dislin).

Thanks to all, who have answered
(per mail or in thread)

For all others, who also don't know how to do I summarize shortly

1. The make_py script looks for the Include and the Config directories.
These are in the Python developers version (python-devel rpm
for SuSE:
PYTH_INC="/usr/include/python2.2/" for python version 2.2
PYTH_CONF="/usr/lib/python2.2/config"
in the appropriate section (lnx for Linux)
2. The DISLIN variable has to be defined, for instance in the shell by
export DISLIN=/usr/local/dislin (default directory)
3. Calling
make_py lnx
for Linux OS
4. Copying the module to the right directory
cp dislinmodule.so /usr/local/dislin/python

Now it should work
