[petsc-users] errors in compiling ~\petsc-3.2-p7\src\ksp\ksp\examples\tutorials\ex2f.F

[Barry Smith]

  Run make ex5f on src/snes/examples/tutorials   

   Does that compile and link correctly? Note all the libraries that being linked (they are printed to the screen) and make sure you have them all.

   Also note that you must use the same BLAS in building PETSc that you link against. So make sure you built PETSc with the mkl libraries.
