[petsc-users] Petsc without debugging enabled

[Barry Smith]

   Hmm, look in  $PETSC_ARCH/include/petscconf.h and look for 

#ifndef PETSC_USE_DEBUG
#define PETSC_USE_DEBUG 1
#endif

is it there? This is what triggers the printing of that message with -log_summary and PETSC_USE_DEBUG is defined in config/PETSc/options/LibraryOptions.py based on 
self.debugging.debugging:  which is set in config/BuildSystem/config/compilerFlags.py  so I am totally lost how it could be printing that message with that choice of configure options. Did you run make all after you ran the ./configure ?
