#!/bin/env python """ This file defines a set of system_info classes for getting information about various resources (libraries, library directories, include directories, etc.) in the system. Currently, the following classes are available: atlas_info atlas_threads_info atlas_blas_info atlas_blas_threads_info lapack_atlas_info blas_info lapack_info openblas_info blas_opt_info # usage recommended lapack_opt_info # usage recommended fftw_info,dfftw_info,sfftw_info fftw_threads_info,dfftw_threads_info,sfftw_threads_info djbfft_info x11_info lapack_src_info blas_src_info numpy_info numarray_info numpy_info boost_python_info agg2_info wx_info gdk_pixbuf_xlib_2_info gdk_pixbuf_2_info gdk_x11_2_info gtkp_x11_2_info gtkp_2_info xft_info freetype2_info umfpack_info Usage: info_dict = get_info() where 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 has options that are the default for each section. The available sections are fftw, atlas, and x11. Appropiate 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. ALL section in site.cfg Only the first complete match is returned. Example: ---------- [ALL] 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] fftw_libs = rfftw, fftw fftw_opt_libs = rfftw_threaded, fftw_threaded # if the above aren't found, look for {s,d}fftw_libs and {s,d}fftw_opt_libs [atlas] library_dirs = /usr/lib/3dnow:/usr/lib/3dnow/atlas # for overriding the names of the atlas libraries atlas_libs = lapack, f77blas, cblas, atlas [x11] library_dirs = /usr/X11R6/lib include_dirs = /usr/X11R6/include ---------- Authors: Pearu Peterson , February 2002 David M.
