This file defines a set of system_info classes for getting
information about various resources (libraries, library directories,
include directories, etc.) in the system. Usage:
info_dict = get_info(<name>)
where <name> is a string 'atlas','x11','fftw','lapack','blas',
'lapack_src', 'blas_src', etc. For a complete list of allowed names,
see the definition of get_info() function below.
Returned info_dict is a dictionary which is compatible with
distutils.setup keyword arguments. If info_dict == {}, then the
asked resource is not available (system_info could not find it).
Several *_info classes specify an environment variable to specify
the locations of software. When setting the corresponding environment
variable to 'None' then the software will be ignored, even when it
is available in system.
Global parameters:
system_info.search_static_first - search static libraries (.a)
in precedence to shared ones (.so, .sl) if enabled.
system_info.verbosity - output the results to stdout if enabled.
The file 'site.cfg' is looked for in
1) Directory of main setup.py file being run.
2) Home directory of user running the setup.py file as ~/.numpy-site.cfg
3) System wide directory (location of this file...)
The first one found is used to get system configuration options The
format is that used by ConfigParser (i.e., Windows .INI style). The
section ALL is not intended for general use.
Appropriate defaults are used if nothing is specified.
The order of finding the locations of resources is the following:
1. environment variable
2. section in site.cfg
3. DEFAULT section in site.cfg
4. System default search paths (see ``default_*`` variables below).
Only the first complete match is returned.
Currently, the following classes are available, along with their section names:

Note that blas_opt_info and lapack_opt_info honor the NPY_BLAS_ORDER
and NPY_LAPACK_ORDER environment variables to determine the order in which
specific BLAS and LAPACK libraries are searched for.
This search (or autodetection) can be bypassed by defining the environment
variables NPY_BLAS_LIBS and NPY_LAPACK_LIBS, which should then contain the
exact linker flags to use (language will be set to F77). Building against
Netlib BLAS/LAPACK or stub files, in order to be able to switch BLAS and LAPACK
implementations at runtime. If using this to build NumPy itself, it is
recommended to also define NPY_CBLAS_LIBS (assuming your BLAS library has a
CBLAS interface) to enable CBLAS usage for matrix multiplication (unoptimized
otherwise).
Example:
----------
[DEFAULT]
# default section
library_dirs = /usr/lib:/usr/local/lib:/opt/lib
include_dirs = /usr/include:/usr/local/include:/opt/include
src_dirs = /usr/local/src:/opt/src
# search static libraries (.a) in preference to shared ones (.so)
search_static_first = 0
[fftw]
libraries = rfftw, fftw
[atlas]
library_dirs = /usr/lib/3dnow:/usr/lib/3dnow/atlas
# for overriding the names of the atlas libraries
libraries = lapack, f77blas, cblas, atlas
[x11]
library_dirs = /usr/X11R6/lib
include_dirs = /usr/X11R6/include
----------
Note that the ``libraries`` key is the default setting for libraries.
