Hi, My school's server has lapack and blas installed. However, I can't get it to be automatically detected by using ./configure. what is the filename that I should used? Is it liblapack.a and libblas.a? I can't find libblas.a in the /usr/lib directory though. Is there another filename for it? I found that if I specify just the dir (/usr/lib) or liblapack.a for both the lapack and blas lib, it won't work
Btw, can I use GotoBlas? I tried to specify libgoto.a or libgoto_northwoodp- r1.10.so and I managed to compile. However, during testing, the error msg are for libgoto.a : /nas/lsftmp/g0306332/petsc-2.3.2-p8/lib/linux-nompi-goto/libpetscksp.so: undefined reference to `pthread_create' /nas/lsftmp/g0306332/petsc-2.3.2-p8/lib/linux-nompi-goto/libpetscksp.so: undefined reference to `dpotrs_' /nas/lsftmp/g0306332/petsc-2.3.2-p8/lib/linux-nompi-goto/libpetscksp.so: undefined reference to `pthread_join' for libgoto_northwoodp-r1.10.so : /nas/lsftmp/g0306332/petsc-2.3.2-p8/lib/linux-nompi-goto/libpetscksp.so: undefined reference to `dpotrs_' That was linked for shared library. If it is for static library, the error is: /nas/lsftmp/g0306332/petsc-2.3.2-p8/lib/linux-nompi-goto/libpetscksp.a( bcgsl.o)(.text+0x103a): In function `KSPSolve_BCGSL': : undefined reference to `dpotrs_' /nas/lsftmp/g0306332/petsc-2.3.2-p8/lib/linux-nompi-goto/libpetscksp.a( bcgsl.o)(.text+0x10f3): In function `KSPSolve_BCGSL': : undefined reference to `dpotrs_' /nas/lsftmp/g0306332/petsc-2.3.2-p8/lib/linux-nompi-goto/libpetscksp.a( bcgsl.o)(.text+0x116f): In function `KSPSolve_BCGSL': : undefined reference to `dpotrs_' /lsftmp/g0306332/GotoBLAS/libgoto.a(blas_server.o)(.text+0x370): In function `blas_thread_init': : undefined reference to `pthread_create' /lsftmp/g0306332/GotoBLAS/libgoto.a(blas_server.o)(.text+0x709): In function `blas_thread_shutdown_': So can gotoblas be used?
