[gdal-dev] GDAL / Python and PPC

[William Kyngesburye]

I guess I don't understand where the problem is.  Here is what I got  
out of your original description of the problem:

   OSX 10.4
   Python 2.5.1 universal binary installed
   no numpy

   build and install numpy from source, but it won't build universal

   GDAL python fails to build because numpy is not universal

When I think about it, the GDAL python libs shouldn't be linking  
directly to the numpy libs anyways.  Python extension libs are really  
loadable modules, like plugins.  The python scripts take care of  
loading those.  So maybe you really mean it's a missing dependency  
problem, not a linking failure?  What is the error when compiling GDAL?

Installing the numpy binary from pythonmac.org is just a convenience  
so you don't have to worry about problems building it universal, which  
is what I think is the source of the GDAL problems.

GDAL doesn't come with its own copy of the numpy source or try to  
build it.

Theory of the Universe

There is a theory which states that if ever anyone discovers exactly  
what the universe is for and why it is here, it will instantly  
disappear and be replaced by something even more bizarrely  
inexplicable.  There is another theory which states that this has  
already happened.
