[petsc-users] MKL library - how to force static linking

[Robert Ellis]

Hi Satish,

I've looked at the Intel docs and find that to have ifort use static MKL libraries I need to add /Qopenmp-link:static to the ifort command. Given this information, is the correct form for the config script (options preceded by - and space separated)?

--FOPTFLAGS='-Qopenmp-link:static -O3'

and the libraries I need are: mkl_intel_lp64.lib, mkl_intel_thread.lib, mkl_core.lib, libiomp5mt.lib

Is the correct form full-pathname-comma-separated?

--with-blas-lapack-lib='/cygdrive/
c/mkl/lib/intel64/mkl_intel_lp64.lib,/cygdrive/c/mkl/lib/intel64/mkl_intel_thread.lib,/cygdrive/c/mkl/lib/intel64/mkl_core.lib,/cygdrive/c/Program\ Files\ \(x86\)/Intel/ComposerXE-2011/compiler/lib/intel64/libiomp5mt.lib'

I've tried various things but keep getting the error

Invalid library: /cygdrive/c/mkl/lib/intel64/mkl_intel_lp64.lib,/cygdrive/c/mkl/lib/intel64/mkl_intel_thread.lib,/cygdrive/c/mkl/lib/intel64/mkl_core.lib,/cygdrive/c/Program\ Files\ \(x86\)/Intel/ComposerXE-2011/compiler/lib/intel64/libiomp5mt.lib for key with-blas-lapack-lib


The following link is helpful for those of us trying to link MKL statically http://software.intel.com/en-us/forums/showthread.php?t=64254

Cheers,
Rob

If you know the correct MLK library list for static linking- you can
try specifying with --with-blas-lapack-lib option

The resultant executable requires MKL dlls to run, specifically fmpich2.dll, libiomp5md.dll, mkl_core.dll, mkl_intel_thread.dll, mpich2mpi.dll. Can I force a static PETSc  build using the MKL libraries? (BTW, using --download-f-blas-lapack produces a statically linked exe.)
