Hello,
I'm working on a project for my training period.My project works fine but i
would track and fix eventual memory leak before using callgring for
optimization.I already use valgrind on this project but since i add libiconv,
valgrind seem not work anymore.
symptoms:Valgrind end processing but don't display any results on memory usage.
But not display error too.
I'v try some ways to run valgrind:valgrind ./Runvalgrind -v ./Runvalgrind -v
--leak-check=full ./Runvalgrind -v --leak-check=full --show-reachable=yes
./Runvalgrind -v --leak-check=full --show-reachable=yes --tool=memcheck
./RunBut i have always the folow result :postgre@debian:/media/sf_oxy$ valgrind
