[petsc-dev] Compiling PETsc against openblas on Linux

Hello everyone. How to configure correctly PETsc compilation against OpenBLAS? 'openblas' libraries are /usr/include/openblas/* /usr/lib(64)/libopenblas.so /usr/lib(64)/libopenblas.a /usr/lib(64)/libopenblas64.so If i use .. --with-openblas=1 \ --with-openblas-include=%{_includedir} \ --wit

Re: [petsc-dev] Compiling PETsc against openblas on Linux

Ah, sorry for the confusion. We do support --download-openblas where PETSc will download and install and OpenBlas for you but if you have it already installed then you need to treat it just as a BLASLAPACK library so use > --with-blaslapack-include=%{_includedir} \ > --with-blaslapack-lib=

It should work. configure.log will have details.. Satish -- balay@asterix /home/balay/petsc (maint=) $ ./configure --with-blaslapack-lib=-lopenblas === Configuring PETSc to compile on your system

--with-blas-lapack-lib=-lopenblas --known-64-bit-blas-indices=0 is working. Thanks. On 31/08/2018 20:11, Satish Balay wrote: > It should work. configure.log will have details.. > > Satish > > -- > > balay@asterix /home/balay/petsc (maint=) > $ ./configure --with-blaslapack-lib=-lopen
