I'm a beginner with petsc, and I'm reading PETSc for Partial Differential Equations.
There is the newest release version (3.18.2) of PETSc's gitlab repo on my device, and openmpi in my system (/usr/sbin/). Here is the repo and what I tried to compiling. p4pdes/e.c at master ยท bueler/p4pdes (github.com) After "make e", I got an excutable file "e". "./e" or "mpiexec -n 4 ./e" can perfectly run. However when I use "petscmpiexec -n 4 ./e", I got some warnings: Warning: ************** The PETSc libraries are out of date Warning: ************** The executable ./e is out of date What should I do to fix the warning? Also this is the first time that I send to a mail-list, if there are some mistakes I made, please tell me. Kind regards, Syvshc
