Source: freefem++ Version: 3.47+dfsg1-1 Severity: normal blacs is about to be removed from the Debian archives, replaced by scalapack2.0 (now in experimental). So the configuration for the freefem++ build will need to be updated to match. configure will need to point the blacs library at -lscalapack$ff_with_mpi instead of -lblacsCinit$ff_with_mpi, etc.
Actually there's another problem. Inspecting the current build logs, neither blacs nor scalapack (the old versions currently still in unstable) are currently being found at build time. The logs (amd64) report: checking check hypre... yes checking check superlu_dist... no checking check superlu... yes checking check superlu4... no checking check blacs... no checking check scalapack... no checking check scotch... no checking check ptscotch... no checking check metis... no checking check metis... yes checking check parmetis... no That should be fixed first, then it will be more clear how to reconfigure for blacs in scalapack2.0.
