[petsc-users] undefined symbol: petsc_null_function_

[Barry Smith]

  Please send make.log and configure.log from building PETSc

   This is a fortran stub function, is there any fortran in your code? 

   If there is no fortran you can reconfigure PETSc with the option -with-fc=0 

   Otherwise we need to track down why it is not being found.
