[Bug 694507] Re: Incorrect path for link libraries from PETSc

 

The attached patch reduces the number of 3rd party libs for both PETSc
and SLEPc to a minimum. This is close to what we had in the SCons based
build system. I have tested the patch with several different
configurations and will apply it unless someone has any objections.

Title:
  Incorrect path for link libraries from PETSc

Status in DOLFIN:
  Confirmed

Bug description:
  The correct path is not being added for some link libraries provided
  by PETSc (specifically, those provided by PCC_LINKER_LIBS).

  I see this when building PETSc and DOLFIN using a locally installed OpenMPI. The consequence is that during configuration I get
  messages like

   Cannot generate a safe runtime search path for target
    dg-advection-diffusion-demo because files in some directories may conflict
    with libraries in implicit directories:

      runtime library [libmpi_f90.so.0] in /usr/lib may be hidden by files in:
        /home/gnw20/local/lib
