Got warnings ldconfig: $HOME/local/lib64/libisl.so.10.0.0-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

Where ELF = Executable and Linkable Format (ELF, formerly called Extensible Linking Format). This is assumed okay as these are python module files, and not shared object files. The .so.10.0.0-gdb.py extention is probabily confusing ldconfig, as least i hope.

Online docs also indicate that reconfiguring ld may fix the problem. If there is problem, try reinstalling binutils?

Python build finished, but the necessary bits to build these modules were not
found:
bsddb185           dl        imageop
sunaudiodev   
To find the necessary bits, look in setup.py in detect_modules() for the
module's name.

Where

• dl is depreciated since Python 2.6, use ctypes instead.
• Beginning in 2.3 some Unix versions of Python may have a bsddb185 module. This is present only to allow backwards compatibility with systems which ship with the old Berkeley DB 1.85 database library. The bsddb185 module should never be used directly in new code. The module has been removed in Python 3. If you find you still need it look in PyPI.
• imageop and sunaudiodev, do not work on 64 bit systems.

$ make test > make.test 2>&1
# ctrl-a ctrl-d to detach screen

As for test_gdb, which i assume is the GNU debugger interfacing module, more information on the error can be obtained by ./python ../Lib/test/regrtest.py -v test_gdb

If this is good enough for your applications proceed with the installation.

$ make install
$ ln -s ~/local/lib/libpython2.7.a ~/local/lib64/

clean up after yourself,

$ rm -r /tmp/$USER/python_build

Then you should see the following

Start with python setup tools, as it contains the easy install tool.

$ cd ~/scratch
$ wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz
$ tar -xf setuptools-0.6c11.tar.gz
$ cd setuptools-0.6c11
$ python setup.py install

Refer to the reference and manual website for further information on using easy install.

Nose is a testing module, used by packages such as Numpy and Scipy. To install simply

$ easy_install nose

An enhanced Interactive Python shell, with lots of goodies …

$ easy_install ipython

mpi4py is python interface to openmpi which is a High Performance Message Passing Library.

To start we are going to build and test the openmpi libraries.

$ cd ~/scratch
$ wget http://www.open-mpi.org/software/ompi/v1.6/downloads/openmpi-1.6.1.tar.bz2
$ tar -xf openmpi-1.6.1.tar.bz2
$ cd openmpi-1.6.1
$ mkdir BUILD
$ cd BUILD
$ ../configure --prefix=$HOME/local --libdir=$HOME/local/lib64

configure taks a minutes or two, with lots of output ….

$ make
$ make check > make.check 2>&1  #takes a minute to complete
$ grep -i -e pass -e fail make.check
$ make install

Download mpi4py

$ cd ~/scratch
$ easy_install --editable --build-directory . mpi4py
$ cd mpi4py
$ python setup.py build 
$ python setup.py test

if no errors install

$ python setup.py install

NumPy is the fundamental package for scientific computing with Python. It contains among other things:

• a powerful N-dimensional array object
• sophisticated (broadcasting) functions
• tools for integrating C/C++ and Fortran code
• useful linear algebra, Fourier transform, and random number capabilities

Based on installation guide.

==== Build ATLAS(3.9.32) with complete Lapack(3.2.2)

From a temporary director ( ie Scratch ) download the latest atlas from Source forge

$ wget http://www.netlib.org/lapack/lapack-3.4.0.tgz
$ wget http://tenet.dl.sourceforge.net/project/math-atlas/Stable/3.10.0/atlas3.10.0.tar.bz2
$ tar -xf atlas3.10.0.tar.bz2
$ mkdir ATLAS/BUILD
$ cd  ATLAS/BUILD
$ ../configure -b 64 -Fa alg -fPIC --shared \
--with-netlib-lapack-tarfile=../../lapack-3.4.0.tgz --prefix=$HOME/usr 

make cd lib make shared make ptshared cd .. make install

Following this guide

Download the LAPACK source and extract, setup make and build as follows,

$ cd ~/scratch
$ wget http://www.netlib.org/lapack/lapack-3.4.1.tgz
$ tar -xf lapack-3.4.1.tgz
$ cd lapack-3.4.1

Setup make,

$ cp make.inc.example make.inc
$ emacs make.inc
# change 
#  OPTS     = -O2  and, NOOPT    = -O0
# to
#  OPTS     = -O2 -fPIC and, NOOPT    = -O0 -fPIC
# save (crtl-x crtl-s) and exit (crtl-x ctrl-c)
$ make blaslib

Make LAPACK

$ screen
$ make all > make.out 2>&1
# crtl-a d
$ tail -f make.out

After 10 minutes make will finish, and you should see test results such as

#Sidenote: To compile with BLAS and LAPACK, set the following variables before building # $ export ATLAS=None # $ export BLAS=None # $ export LAPACK=None

Set blas and lapack paths

$ export ATLAS=None
$ export BLAS=$HOME/local/lib64/librefblas.a
$ export LAPACK=$HOME/local/lib64/liblapack.a

Build and install

$ python setup.py build --fcompiler=gnu95
$ python setup.py install

Then test it (note this requires nose)

$ cd ~
$ ipython
$ import numpy
$ numpy.test()

$ cd ~/scratch
$ wget http://tenet.dl.sourceforge.net/project/scipy/scipy/0.10.1/scipy-0.10.1.tar.gz
$ tar -xf scipy-0.10.1.tar.gz 
$ cd scipy-0.10.1/

Set blas and lapack paths

$ export ATLAS=None
$ export BLAS=$HOME/local/lib64/librefblas.a
$ export LAPACK=$HOME/local/lib64/liblapack.a

Build it, which takes a while

$ python setup.py build

Install it

$ python setup.py install 

Once the build has been successfully completed, its time to install and test scipy

$ python setup.py install
$ cd ~
$ ipython
$ import scipy
$ scipy.test()

which did not work 100 % :(
