How to compile gdal against a user specified numpy
I THINK the GDAL build calls python distutils (setup.py) to do the
actual python extension build.
Ideally, the setup.py uses
numpy.get_include() to get the numpy include directory.
If so, it should "just work" with your setup, so I'd poke around and see
if that's the case. If it is finding the numpy includes a different way,
then that would explain your problem.
If it is set up this way, I'd track through the Python part of the
build, and see how python is called, etc.
HTH,

1) I got the latest SVN from numpy and scipy and compiled into user
specific directory using --prexif=mydir. numpy test are all sucessfull,
scipy shows two errors.
Specified
export PYTHONPATH='/media/work/hannes/lib/python2.6/site-packages'
so my python installation always loads the user specified numpy and
scipy first.
2) Download the latest stable 1.7.2 gdal from svn and compiled to the
same directory using
export LD_LIBRARY_PATH=/media/work/hannes/lib:$LD_LIBRARY_PATH
./configure --prefix=/media/work/hannes --libdir=/media/work/hannes
make
make install --prefix=/media/work/hannes
## made a try without specifying --libdir
go into python

from osgeo import gdal_array
RuntimeError: module compiled against version 1000009 of C-API but this

I seem to miss the switch to tell it to use a local numpy for gdal !!!
Any advice ? (BTW, import numpy.core.multiarray diretly in python works)
Which switch do I miss here, probably somewhere in ./configure ?
Hannes
PS. I regenerate the python swig bindings using make etc, still does not
help.
Comment1:
If I remember correctly ./configure -with--python reported to screen
that the python-gdal files are written to the default installation
directory and not to the --prefix dir, but did not save the screen
output for that error message.. sorry
