#!/usr/bin/env python3 """ 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: Numeric_info:Numeric _numpy_info:Numeric _pkg_config_info:None accelerate_info:accelerate agg2_info:agg2 amd_info:amd atlas_3_10_blas_info:atlas atlas_3_10_blas_threads_info:atlas atlas_3_10_info:atlas atlas_3_10_threads_info:atlas atlas_blas_info:atlas atlas_blas_threads_info:atlas atlas_info:atlas atlas_threads_info:atlas blas64__opt_info:ALL # usage recommended (general ILP64 BLAS, 64_ symbol suffix) blas_ilp64_opt_info:ALL # usage recommended (general ILP64 BLAS) blas_ilp64_plain_opt_info:ALL # usage recommended (general ILP64 BLAS, no symbol suffix) blas_info:blas blas_mkl_info:mkl blas_ssl2_info:ssl2 blas_opt_info:ALL # usage recommended blas_src_info:blas_src blis_info:blis boost_python_info:boost_python dfftw_info:fftw dfftw_threads_info:fftw djbfft_info:djbfft f2py_info:ALL fft_opt_info:ALL fftw2_info:fftw fftw3_info:fftw3 fftw_info:fftw fftw_threads_info:fftw flame_info:flame freetype2_info:freetype2 gdk_2_info:gdk_2 gdk_info:gdk gdk_pixbuf_2_info:gdk_pixbuf_2 gdk_pixbuf_xlib_2_info:gdk_pixbuf_xlib_2 gdk_x11_2_info:gdk_x11_2 gtkp_2_info:gtkp_2 gtkp_x11_2_info:gtkp_x11_2 lapack64__opt_info:ALL # usage recommended (general ILP64 LAPACK, 64_ symbol suffix) lapack_atlas_3_10_info:atlas lapack_atlas_3_10_threads_info:atlas lapack_atlas_info:atlas lapack_atlas_threads_info:atlas lapack_ilp64_opt_info:ALL # usage recommended (general ILP64 LAPACK) lapack_ilp64_plain_opt_info:ALL # usage recommended (general ILP64 LAPACK, no symbol suffix) lapack_info:lapack lapack_mkl_info:mkl lapack_ssl2_info:ssl2 lapack_opt_info:ALL # usage recommended lapack_src_info:lapack_src mkl_info:mkl ssl2_info:ssl2 numarray_info:numarray numerix_info:numerix numpy_info:numpy openblas64__info:openblas64_ openblas64__lapack_info:openblas64_ openblas_clapack_info:openblas openblas_ilp64_info:openblas_ilp64 openblas_ilp64_lapack_info:openblas_ilp64 openblas_info:openblas openblas_lapack_info:openblas sfftw_info:fftw sfftw_threads_info:fftw system_info:ALL umfpack_info:umfpack wx_info:wx x11_info:x11 xft_info:xft 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.
