petsc and slepc incompatibility

[idontgetoutmuch]

I abandoned my efforts with homebrew and managed to install petsc 3.7 using ./install-petsc.sh. But then slepc failed to install

./install-slepc.sh $SLEPC_VERSION $SLEPC_DIR

I see you have already tripped over this.

Did you go back to an earlier version of petsc?

I managed to get both slepc and petsc to install both from tags 3.6.3 but now I get

/Users/dom/petsc-hs/src/Numerical/PETSc/Internal/InlineC.c:2:23:
     fatal error: petscsnes.h: No such file or directory
compilation terminated.
Completed 2 action(s).

    Process exited with code: ExitFailure 1

and there is no such file in my petsc installation.

My include files were incorrect. I am now using

~/petsc-hs $ stack install
--extra-lib-dirs=/Users/dom/petsc/arch-darwin-c-debug/lib
--extra-lib-dirs=/Users/dom/slepc/arch-darwin-c-debug/lib
--extra-include-dirs=/Users/dom/petsc/include
--extra-include-dirs=/Users/dom/slepc/include

but now I get a different error

/Users/dom/petsc-hs/src/Numerical/PETSc.hs:3:1: Warning:
    The import of ‘Numerical.PETSc.Internal.PutGet’ is redundant
      except perhaps to import instances from ‘Numerical.PETSc.Internal.PutGet’

It has now installed - that was something of an odyssey.

stack install

Yes, the PETSc architecture (and SLEPc too) requires both the main includes and the header files generated after compilation. This information was already present both in the provided Makefile, in stack-build.sh and in the Travis CI file.

Re. the latest PETSc, I'll try to support PETSc 3.7 after SLEPc 3.7 becomes available (upcoming weeks).
