[Numpy-discussion] Installing on CentOS 5 claims invalid Python installation
Mon Dec 27 13:40:11 CST 2010
Hi Bruce and Chris,
This was a user build and install of Python (particularly 2.6.6 since
2.7.1 has build troubles on CentOS 5). The original python 2.4 in the
system is ignored for this effort because I can't get to it. Since I
was unfamiliar with building Python from source I didn't know it should
produce python development where the --prefix points the install. It is
supposed to under the altinstall target.
By looking at the make I found(with the autoconf 2.63 version) the make
altinstall target simply wasn't running all its subtargets even though
no install error occurred. Ran the inclinstall, libainstall,
sharedinstall targets and the distribution was populated with the devel
In fact the top of the configure.in of python 2.6.6 source build it says
dnl NOTE: autoconf 2.64 doesn't seem to work (use 2.61).
and I was at 2.63; not sure if same problem they were noting.
This is all python install issues and has nothing to do with numpy
install. The numpy install followed:
#python2.6 setup.py clean
python2.6 setup.py build --fcompiler=gnu95
python2.6 setup.py install
Then a quick test:
Python 2.6.6 (r266:84292, Dec 22 2010, 13:28:53)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> a = numpy.arange(10).reshape(2,5)
array([[0, 1, 2, 3, 4],
[5, 6, 7, 8, 9]])
Python 3.2 didn't have any of the python install issues and numpy
installs and functions on it too.
Now on to h5py utilizing numpy. Thanks for the discussion; you lead me
to understand when building python from source the devel portion should
