[petsc-users] Troubles installing PETSc

[Justin Dong (Me)]

Hi Matt,

I’ve checked out the section on makefiles and am not really sure what I could be doing incorrectly. I’m positive $PETSC_DIR is set correctly. I’m on MAC OS X 10.9 right now and have $PETSC_ARCH set as linux-gnu.

According to the example I linked to below, I should just type “make ex2”, which gives me the error I listed. In the user manual, I try the suggestion “make PETSC_ARCH=arch ex2” with arch replaced by linux-gnu and I still get the same error. I haven’t messed with the makefile at all, and if I’ve set $PETSC_DIR and $PETSC_ARCH correctly, it should be fine, right?

Any other tips?

Thanks,
Justin
