Hi, I'm trying to build numpy from svn on ubuntu edgy with atlas provided by ubuntu package atlas3-sse2-dev which contains:
/usr /usr/lib /usr/lib/sse2 /usr/lib/sse2/libatlas.a /usr/lib/sse2/libcblas.a /usr/lib/sse2/libf77blas.a /usr/lib/sse2/liblapack_atlas.a /usr/lib/atlas /usr/lib/atlas/sse2 /usr/lib/atlas/sse2/libblas.a /usr/lib/atlas/sse2/liblapack.a /usr/share /usr/share/doc /usr/share/doc/atlas3-sse2-dev /usr/share/doc/atlas3-sse2-dev/copyright /usr/share/doc/atlas3-sse2-dev/changelog.Debian.gz /usr/lib/sse2/libatlas.so /usr/lib/sse2/libcblas.so /usr/lib/sse2/libf77blas.so /usr/lib/sse2/liblapack_atlas.so /usr/lib/atlas/sse2/libblas.so /usr/lib/atlas/sse2/liblapack.so I tried both with and without a site.cfg: [DEFAULT] library_dirs = /usr/lib/sse2 include_dirs = /usr/include [blas_opt] libraries = f77blas, cblas, atlas [lapack_opt] libraries = lapack, f77blas, cblas, atlas and tested wether numpy is actually using the optimized libs as demonstrated in a posting by Simon Burton (http://article.gmane.org/gmane.comp.python.numeric.general/5849). It apparently is linked to /usr/lib/sse2/libatlas.so.3.0 /usr/lib/sse2/libcblas.so.3.0 /usr/lib/sse2/libf77blas.so.3.0 /usr/lib/python2.4/site-packages/numpy/linalg/lapack_lite.so The optimized lapack lib is not used. This is consistent with the output of the build script: [EMAIL PROTECTED]:~/prog/scipy/numpy$ python setup.py build Running from numpy source directory. non-existing path in 'numpy/distutils': 'site.cfg' F2PY Version 2_3714 blas_opt_info: blas_mkl_info: libraries mkl,vml,guide not found in /usr/local/lib libraries mkl,vml,guide not found in /usr/lib NOT AVAILABLE atlas_blas_threads_info: Setting PTATLAS=ATLAS libraries ptf77blas,ptcblas,atlas not found in /usr/local/lib libraries ptf77blas,ptcblas,atlas not found in /usr/lib/atlas libraries ptf77blas,ptcblas,atlas not found in /usr/lib/sse2 libraries ptf77blas,ptcblas,atlas not found in /usr/lib NOT AVAILABLE atlas_blas_info: libraries f77blas,cblas,atlas not found in /usr/local/lib libraries f77blas,cblas,atlas not found in /usr/lib/atlas FOUND: libraries = ['f77blas', 'cblas', 'atlas'] library_dirs = ['/usr/lib/sse2'] language = c customize GnuFCompiler customize GnuFCompiler customize GnuFCompiler using config compiling '_configtest.c': /* This file is generated from numpy_distutils/system_info.py */ void ATL_buildinfo(void); int main(void) { ATL_buildinfo(); return 0; } C compiler: gcc -pthread -fno-strict-aliasing -DNDEBUG -g -O2 -Wall -Wstrict-prototypes -fPIC compile options: '-c' gcc: _configtest.c gcc -pthread _configtest.o -L/usr/lib/sse2 -lf77blas -lcblas -latlas -o _configtest ATLAS version 3.6.0 built by root on Fri Jan 9 15:57:20 UTC 2004: UNAME : Linux intech67 2.4.20 #1 SMP Fri Jan 10 18:29:51 EST 2003 i686 GNU/Linux INSTFLG : MMDEF : /fix/g/camm/atlas3-3.6.0/CONFIG/ARCHS/P4SSE2/gcc/gemm ARCHDEF : /fix/g/camm/atlas3-3.6.0/CONFIG/ARCHS/P4SSE2/gcc/misc F2CDEFS : -DAdd__ -DStringSunStyle CACHEEDGE: 1048576 F77 : /usr/bin/g77, version GNU Fortran (GCC) 3.3.3 20031229 (prerelease) (Debian) F77FLAGS : -fomit-frame-pointer -O CC : /usr/bin/gcc, version gcc (GCC) 3.3.3 20031229 (prerelease) (Debian) CC FLAGS : -fomit-frame-pointer -O3 -funroll-all-loops MCC : /usr/bin/gcc, version gcc (GCC) 3.3.3 20031229 (prerelease) (Debian) MCCFLAGS : -fomit-frame-pointer -O success! removing: _configtest.c _configtest.o _configtest FOUND: libraries = ['f77blas', 'cblas', 'atlas'] library_dirs = ['/usr/lib/sse2'] language = c define_macros = [('ATLAS_INFO', '"\\"3.6.0\\""')] lapack_opt_info: lapack_mkl_info: mkl_info: libraries mkl,vml,guide not found in /usr/local/lib libraries mkl,vml,guide not found in /usr/lib NOT AVAILABLE NOT AVAILABLE atlas_threads_info: Setting PTATLAS=ATLAS libraries ptf77blas,ptcblas,atlas not found in /usr/local/lib libraries lapack_atlas not found in /usr/local/lib libraries ptf77blas,ptcblas,atlas not found in /usr/lib/atlas libraries lapack_atlas not found in /usr/lib/atlas libraries ptf77blas,ptcblas,atlas not found in /usr/lib/sse2 libraries ptf77blas,ptcblas,atlas not found in /usr/lib libraries lapack_atlas not found in /usr/lib numpy.distutils.system_info.atlas_threads_info NOT AVAILABLE atlas_info: libraries f77blas,cblas,atlas not found in /usr/local/lib libraries lapack_atlas not found in /usr/local/lib libraries f77blas,cblas,atlas not found in /usr/lib/atlas libraries lapack_atlas not found in /usr/lib/atlas libraries lapack not found in /usr/lib/sse2 libraries f77blas,cblas,atlas not found in /usr/lib libraries lapack_atlas not found in /usr/lib numpy.distutils.system_info.atlas_info /media/hda6/home/ck/prog/scipy/numpy/numpy/distutils/system_info.py:903: UserWarning: ********************************************************************* Could not find lapack library within the ATLAS installation. ********************************************************************* warnings.warn(message) FOUND: libraries = ['f77blas', 'cblas', 'atlas'] library_dirs = ['/usr/lib/sse2'] language = c define_macros = [('ATLAS_WITHOUT_LAPACK', None)] lapack_info: libraries lapack not found in /usr/local/lib libraries lapack not found in /usr/lib NOT AVAILABLE Confusingly lapack_atlas resides in /usr/lib but even though setup.py looks for it in that place it reports 'not found'. What should I try next? Thanks, Christian _______________________________________________ Numpy-discussion mailing list [EMAIL PROTECTED] http://projects.scipy.org/mailman/listinfo/numpy-discussion
