[Plplot-general] Re: Plplot 5.0.4-5 pn RedHat 7.2

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

I am going to put this on the list because others may be interested as well.

I don't have access to RH 7.2.  My guess is the configure part of your build
is not finding one of python or numpy header files.  The build then
continues fine but excludes plmodule.so as it should.  Finally, at the end
since plmodule.so is on the list of files to be installed rpm complains that
it wasn't built and quits.

If my guess is correct there are two solutions to the problem.

(1) If you don't care about python, simply comment out the plmodule.so
file list line from the spec file.

(2) Get to the bottom of why plplot is not finding one or both of the
python headers or the numpy headers.  It essentially looks for Python.h and
arrayobject.h.  Are those both somewhere on your system? If not, there might
be development versions of the python and numeric packages you still have to
install.  If they are both there, you probably have to modify plplot
configuration a little by setting environment variables to help configure
for plplot find the headers.  The relevant variables are PYTHON_INC_DIR and
PYTHON_NUM_DIR.  I haven't tried this but try setting these environment
variables respectively to the directories where Python.h and arrayobject.h
are located.  This should occur just before the configure step in the spec
file. With this change to the spec file, I think configure will go ahead and
configure python and numpy properly. Give it a try, and let me know whether
it works.  (If it doesn't work, let me know all the messages that you get
from configure.  If those are okay for python, then you are probably
generating plmodule.so OK, and you may simply have to change the directory
in the specfile file list which identifies where plmodule.so is installed.)

BTW, if you want to look deeper at what is going on, look at cf/sysloc.in.
(look for Python and arrayobject within that file).  That is where I got the
information about PYTHON_INC_DIR and PYTHON_NUM_DIR.  There is a list there
of possible directories to search (if PYTHON_INC_DIR is not defined). It is
an ongoing issue with us that that directory list has to be updated every
time there is a new version of python or numpy.  The CVS version of
cf/sysloc.in (which will eventually be part of the next stable release of
plplot) has a more extended list of directories to search.  But I think
setting PYTHON_INC_DIR and PYTHON_NUM_DIR is probably the easiest thing for
you to do for now.
