Hi everyone, I am trying to install a package called PySparse. I have modified the paths in the template site.cfg file. It appears that during the built process it compiles numpy as well, because the error messages I get are all over the numpy mailing list (I did not find one addressing my problem exactly). My MKL libs are installed at "/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64" . There are BLAS / LAPACK libraries here (I provided the library mkl_rt.so to SuiteSparse for instance, and it resolved all LAPACK and BLAS dependencies that way). But for some reason "/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64" does not work in the built process below, in what I think is a numpy installer. The output shows that the directory is searched, but that the result is "NOT AVAILABLE". Could someone give me a pointer for why my the MKL/BLAS/LAPACK dependencies cannot be resolved? It would be very appreciated sincerely, Bram --------------------------------------------------------------------------- PART OF THE OUTPUT OF PySparse SETUP.PY --------------------------------------------------------------------------- blas_opt_info: blas_mkl_info: libraries mkl,vml,guide not found in ['/usr/local/lib', '/wgdisk/hy3300/re15/lwillemsen/local_install/lib', '/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64'] NOT AVAILABLE openblas_info: libraries not found in ['/usr/local/lib', '/wgdisk/hy3300/re15/lwillemsen/local_install/lib', '/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64'] NOT AVAILABLE atlas_blas_threads_info: Setting PTATLAS=ATLAS libraries ptf77blas,ptcblas,atlas not found in ['/usr/local/lib', '/wgdisk/hy3300/re15/lwillemsen/local_install/lib', '/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64'] NOT AVAILABLE atlas_blas_info: libraries f77blas,cblas,atlas not found in ['/usr/local/lib', '/wgdisk/hy3300/re15/lwillemsen/local_install/lib', '/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64'] NOT AVAILABLE blas_info: libraries blas not found in ['/usr/local/lib', '/wgdisk/hy3300/re15/lwillemsen/local_install/lib', '/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64'] NOT AVAILABLE blas_src_info: NOT AVAILABLE NOT AVAILABLE No blas info found Sparse:: Using BLAS info: {} Using dflt_lib_dirs = /usr/local/lib:/wgdisk/hy3300/re15/lwillemsen/local_install/lib:/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64 Using dflt_libs = [] No blas info found Eigen:: Using BLAS info: {} lapack_opt_info: lapack_mkl_info: mkl_info: libraries mkl,vml,guide not found in ['/usr/local/lib', '/wgdisk/hy3300/re15/lwillemsen/local_install/lib', '/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64'] 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 /wgdisk/hy3300/re15/lwillemsen/local_install/lib libraries lapack_atlas not found in /wgdisk/hy3300/re15/lwillemsen/local_install/lib libraries ptf77blas,ptcblas,atlas not found in /wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64 libraries lapack_atlas not found in /wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64 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 /wgdisk/hy3300/re15/lwillemsen/local_install/lib libraries lapack_atlas not found in /wgdisk/hy3300/re15/lwillemsen/local_install/lib libraries f77blas,cblas,atlas not found in /wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64 libraries lapack_atlas not found in /wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64 numpy.distutils.system_info.atlas_info NOT AVAILABLE lapack_info: libraries lapack not found in ['/usr/local/lib', '/wgdisk/hy3300/re15/lwillemsen/local_install/lib', '/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64'] NOT AVAILABLE lapack_src_info: NOT AVAILABLE NOT AVAILABLE No lapack info found Eigen:: Using LAPACK info: {} non-existing path in 'pysparse/eigen': '/usr/local/lib:/wgdisk/hy3300/re15/lwillemsen/local_install/lib:/wgdisk/omega2dev2/env/EL5/intel/composer_xe_2013.0.079/mkl/lib/intel64' No blas info found Direct:: Using BLAS info: {}
