Hi all, I wonder if Peter finally got Gotoblas working with numpy. I am trying with gotoblas 1.13 installed in the same way: $ ls -R .: include lib ./include: goto ./include/goto: blaswrap.h cblas.h clapack.h f2c.h ./lib: libgoto2.a libgoto2_nehalemp-r1.13.a libgoto2_nehalemp-r1.13.so libgoto2.so and numpy 1.5.1 with this site.cfg [DEFAULT] library_dirs = /usr/local/gcc/4.5.2/gcc/lib64:/usr/local/gcc/4.5.2/gcc/lib:/usr/local/gcc/4.5.2/gcc/lib32:/usr/local/gcc/4.5.2/gotoblas2/1.13/lib:/usr/local/gcc/4.5.2/suiteSparse/3.6.0/lib:/usr/local/gcc/4.5.2/fftw/3.2.2/lib include_dirs = /usr/local/gcc/4.5.2/gcc/include:/usr/local/gcc/4.5.2/gotoblas2/1.13/include/goto:/usr/local/gcc/4.5.2/suiteSparse/3.6.0/include:/usr/local/gcc/4.5.2/fftw/3.2.2/include search_static_first = 1 [blas_opt] libraries = goto2 language = fortran [lapack_opt] libraries = goto2 language = fortran [amd] amd_libs = amd [umfpack] umfpack_libs = umfpack [fftw] libraries = fftw3 (I also tried without "_opt" and "language = fortran"); I used goto2 for lapack because I read lapack should be included in libgoto (anyway things do not change using "lapack"). I am quite sure the system is not using my goto-lapack stuff since every time I buid i get: building extension "numpy.numarray._capi" sources building extension "numpy.fft.fftpack_lite" sources building extension "numpy.linalg.lapack_lite" sources creating build/src.linux-x86_64-2.7/numpy/linalg *### Warning: Using unoptimized lapack ###* * adding 'numpy/linalg/lapack_litemodule.c' to sources.* adding 'numpy/linalg/python_xerbla.c' to sources. adding 'numpy/linalg/zlapack_lite.c' to sources. adding 'numpy/linalg/dlapack_lite.c' to sources. adding 'numpy/linalg/blas_lite.c' to sources. adding 'numpy/linalg/dlamch.c' to sources. adding 'numpy/linalg/f2c_lite.c' to sources. building extension "numpy.random.mtrand" sources creating build/src.linux-x86_64-2.7/numpy/random C compiler: /usr/local/gcc/4.5.2//gcc/bin/gcc -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -O1 -pthread -fPIC -march=native -mtune=native -I/usr/local/gcc/4.5.2//gcc/include -I/usr/local/gcc/4.5.2//suiteSparse/3.6.0/include -I/usr/local/gcc/4.5.2//fftw/3.2.2/include -fPIC during numpy installation (which ends successfully). Moreover I cannot see any -lgoto2 as I would have expected. Incidentally, I cannot see -lamd, -lumfpack, -lfftw3 (or any reference to amd, umfpack, fftw3) neither, although there seems to be something to handle them in system_info.py. The failure is so complete that I must have done some big mistake but I can't correct my site.cfg even after searching the internet. This seems to be one of the major discussion about this topic so I am asking here for some help, please. Is the problem related with site.cfg or with gotoblas2 installation? Is it true that gotoblas2 hosts a full lapack inside? thank you very much! giuseppe
