[petsc-users] Elemental support is outdated?

[Denis Davydov]

I already tried building PETSc with 0.87.7, the error is:

petsc-3.7.6/src/mat/impls/elemental/matelem.cxx:653:7: error: no matching function for call to 'SolveAfter'
      El::lu::SolveAfter(El::NORMAL,*a->emat,*a->pivot,xer);
      ^~~~~~~~~~~~~~~~~~
elemental-0.87.7-arf6zkytd5mmyckplcrjiin3zapbhvyt/include/El/lapack_like/factor.hpp:552:6: note: candidate function [with Field = double] not viable: no known conversion from 'El::DistMatrix<PetscInt, El::VC, El::STAR>' (aka 'DistMatrix<int, El::VC, El::STAR>') to 'const El::DistPermutation' for 3rd argument


strangely enough I have the same issues with 0.87.4:


/petsc-3.7.6/src/mat/impls/elemental/matelem.cxx:653:7: error: no matching function for call to 'SolveAfter'
      El::lu::SolveAfter(El::NORMAL,*a->emat,*a->pivot,xer);
