Hello,
at some point the configuration script prints a warning that valgrind is not
found in the system.
Is petsc going to link some valgrind related libraries if valgrind is installed?
PETSc does not link any valgrind libraries, but if valgrind.h is found
PETSc does include it and use it to determine if valgrind is running (when
PETSc is run under valgrind we turn off all the PETSc memory error detection so
that valgrinds will find any problems and not get confused by our own memory
checking). For C and C++ programming valgrind is an enormously powerful tool,
taking seconds to find memory bugs that manually would take hours by experts;
unless you are one of the few who never put bugs into code we highly recommend
installing it and learning a little about it.
