[SciPy-user] Compilation Scipy 0.3.2

[Mickael Profeta]

Hi

I try to compile scipy_complet 0.3.2 on a Linux platform with gcc 3.4.3, 
python 2.4, fftw 2.1.5 and F2PY-2.45.241_1926.

I found some troubles in the compilation of ffpack, and after 
investigation, it seems to be related with all fortran libraries wrapped 
with scipy.

The error is for example this one:

gcc options: '-pthread -fno-strict-aliasing -DNDEBUG -g -O3 -Wall 
-Wstrict-proto+types -I/scisoft/ESRF_sw/linux_i386_03/include -fPIC'

-I/scisoft/ESRF_sw/linux_i386_03/include -Ibuil+d/src

To solve the compilation problem, it is necessary to add -shared to link 
step. But I do not understand why this -shared is not present. This 
seems to be related with scipy-distutils:


% python scipy_distutils/gnufcompiler.py config_fc --verbose
customize GnuFCompiler
GnuFCompiler instance properties:
  archiver        = ['ar', '-cr']
  compile_switch  = '-c'
  compiler_f77    =
['/mntdirect/_scisoft/ESRF_sw/linux_i386_03/bin/g77', '-Wall', 
'-fno-second-underscore', '-fPIC', '-O3',
'-funroll  -loops']
  compiler_f90    = None
  compiler_fix    = None
  libraries       = ['g2c']
  library_dirs    = []
  linker_so       =
['/mntdirect/_scisoft/ESRF_sw/linux_i386_03/bin/g77', 
'-L/scisoft/ESRF_sw/linux_i386_03/lib']
  object_switch   = '-o '
  ranlib          = ['ranlib']
  version_cmd     =
['/mntdirect/_scisoft/ESRF_sw/linux_i386_03/bin/g77', '
                    --version']
3.4.3


linker_so does not contains the -shared flag.
Does anyone got an idea on how to solve the problem, I get lost with all 
setup.py...

Thanks for help
