Re: [petsc-users] dyld: Symbol not found: _MatCreate_MPIAIJViennaCL

Hi,

yes, Satish is right, this build is a CPU-build. Add `--with-opencl=1` :-)

Best regards,
Karli

 From prior e-mail - you wanted to use AMD GPU on OSX. This build below is CPU 
build - not for GPU. [Karl can confirm]

I think OSX has OpenCL installed by default [perhaps via xcode?] - so you might 
just need the additional configure option: --with-opencl=1

I guess you are running viennacl (opencl) on CPU.

please try the attached patch.

cd petsc
patch -Np1 < viennacl.patch

Or use branch balay/viennacl-cpu-check/maint in petsc repo
