hi
i need help to use ValGrind for memory checking of openscada source codes.
the ValGrind finds memory leakage but it doesnt show me line number to fix it.
i tried to compile openscada with gcc -g or -O0 but gcc compiler return me alot of error message.(i have testet widget.cpp; tsys.cpp; tcrnode.cpp with valgrind)
do you know is it related to openscada version that i am using?(I am using 0.8.0.10)
how can i fix gcc error messages to prepare code for profiling with valgrind?
tnx

Why? I haven't get into OpenSCADA the memory leaks but it early also tested by ValGrind!

The version is too old and there allowed 0.8.16 version yet and more, for all like actions you must use 0.9 Work version instead!

You must know it if you try to do that or use the ready builds with the debug information's packages!

tnx for response.
i need to profile memory usage because when i run the QT visualization of the project my system experience high memory usage and works slow.
(0.8.0.10)
i read valgrind tutorial and it said that to have line number of error, you need to compile the code with gcc.
