Re: [Plplot-general] Configure Bug?

[Alan W. I. <ir...@be...>]

The configure script is set up so you can override it by setting environment
variables.  For example, I use this approach to make RedHat rpm's.

You didn't say, but your situation sounds like you may be using RedHat.
RedHat's python command refers to python 1.5 while they use the python2
command to refer to python 2.x.  Since their default python command refers
to version 1.5, that is what I always use for RH.

If you don't have RedHat the following instructions may still
work for you.

(1) Download the appropriate Numeric rpm from
http://prdownloads.sf.net/numpy/ and install it.

python-numpy-15.3-1.i386.rpm is appropriate for python 1.5 while I believe
from the numbering scheme (multiply python version by 10 to get appropriate
numeric version) that Numeric-21.0-1.i386.rpm will be appropriate for
python2.1 and Numeric-22.0-1.i386.rpm will be appropriate for python-2.2

(2) Study plplot_redhat7.2.spec at
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/plplot/plplot/rpm/. This
RH 7.2 spec file uses the following commands to set up environment variables
before configuring:
PY_VERSION=`python -c 'import sys ; print sys.version[0:3]'`
export PYTHON_INC_DIR=/usr/include/python${PY_VERSION}/
echo PYTHON_INC_DIR=${PYTHON_INC_DIR}
export PYTHON_MOD_DIR=/usr/lib/python${PY_VERSION}/
export PYTHON_CFG_DIR=${PYTHON_MOD_DIR}/config
export PYTHON_NUM_DIR=${PYTHON_INC_DIR}/Numeric/
export PYTHON_MACH_DIR=${PYTHON_MOD_DIR}/site-packages
export PYTHON_DIR=${PYTHON_MACH_DIR}

The above PY_VERSION variable uses the python command (as opposed to
python2) so that is how you get python-1.5 on RedHat.  I won't try version 2
of python on RedHat until it becomes the default that you get with the
"python" command.  For Debian, version 2.1 of python is the default, and that
works fine with plplot along with the python-numeric deb which is version
21.0 (see above comments on appropriate version of Numeric to use).

Note the above spec file was used to build the RH 7.2 rpm's we have
distributed, and those rpm's work fine.

Note we also have a RH7.3 spec file in the same location. This spec file
differs little from the RH7.2 version but is still a work in progress for
the current CVS version of PLplot.  On RH 7.3 it works fine for building the
python interface to the plplot CVS version, but after the python interface
is built and installed, the rpm goes on to attempt to install the plplot
tcl/tk interface, and there are some problems due to the combination of
RH7.3 and our plplot CVS version that we are still working out.
