[petsc-dev] *****SPAM*****Re: how to solve this problem ?

1. It's just a warning
   https://askubuntu.com/questions/925485/created-in-deterministic-mode-error/925511

2. You wouldn't normally run make from that subdirectory

3. You're running a rather old version of PETSc, and especially if you're extending/debugging PETSc, please switch to the latest version
