[Matplotlib-users] matplotlib Redhat 9.0 install problems

[David F. <df...@uc...>]

Hi, I'm new to using matplotlib and am having some problems installing 
the software package. Basically my setup is:
* Redhat 9.0
* gcc 3.3
* Python 2.4 (installed in a non-standard location)
* freetype 2.1.9 and numarray 1.2.2 also installed in a non-standard 
location.


Following the instructions on the matplotlib homepage, I:
1. Substitute:
	'linux2' : [
with:
	'linux2' : [os.environ['ACSROOT'], os.environ['PYTHON_ROOT']

within matplotlib-0.72.1/setupext.py. The ACSROOT environment variable 
is where numarray is installed and the numarray headers can be found in 
$ACSROOT/include/numarray/.
2. Set BUILD_AGG=1
3. Run the command 'python setup.py build' which gives output that looks 
correct until gcc is executed:
	running build_ext
	building 'matplotlib._na_transforms' extension
	creating build/temp.linux-i686-2.4

Just looking at the output it appears as if the changes made to basedir 
(i.e., 'linux2') in setupext.py are not having any sort of effect (hence 
the error message about numarray/arrayobject.h not existing). Is there 
something blatantly wrong I'm doing? Any help would be greatly appreciated.

Thanks in advance,

No, it looks like we are doing something wrong.  I can't believe it
has not been reported in the umpteen mpl releases that have had this
problem....

build_transforms needs to call

  add_base_flags(module)

before the call to 

        ext_modules.append(module)

in both the Numeric and numarray sections.  Ditto for the
build_contour function in setupext.py.

Hope this helps!  Let me know...

Yes, this fixed it! Thank you.

BTW
A new identical problem appeared which was easily fixed by doing the 
same thing to the build_contour function.

There are 10 types of people in the world. Those that understand binary

Which is why I said "Ditto for the build_contour function in
setupext.py" <wink>

Glad it helped -- thanks for the report and persevering!
