Building and Installing NumPy? 1.2.1 on the BG/P (Surveyor)

These instructions assume bash.

• Copy site.cfg.example to site.cfg then add:

[DEFAULT]
library_dirs = /soft/apps/ESSL-4.4/lib
include_dirs = /soft/apps/ESSL-4.4/include
libraries = mass, x1, xlopt, xlf90_r, xlfmath, xlsmp
search_static_first = true

• Set environment variables:

ldpath=/bgsys/drivers/ppcfloor/gnu-linux/lib
ldflags="-Wl,--allow-multiple-definition -L/opt/ibmcmp/xlmass/bg/4.4/bglib"
root=$HOME/soft/numpy-1.2.1-essl
p=/bgsys/drivers/ppcfloor/gnu-linux/bin/python
c='"/bgsys/drivers/ppcfloor/gnu-linux/bin/powerpc-bgp-linux-gcc -DNO_APPEND_FORTRAN -L/opt/ibmcmp/xlmass/bg/4.4/bglib"'

• Now build and install numpy:

  MATHLIB="mass" LDFLAGS="$ldflags" LD_LIBRARY_PATH="$ldpath" CC="$c" $p setup.py install --root="$root"
