[petsc-dev] wrong makefile variables?

[Barry Smith]

  Maybe if you told/showed me exactly how you use it we can come up with the optimal set of variables you want?

   Do you want a flag that says single library or multiple libraries?

   Do you want a variable with the list of the PETSc libraries? 

   Something else?
