Memory leak

**vvbkumar** · 30th August 2006, 16:56

hi

I have a C++ project (application).

But unfortunately there are memory leaks in it(I am told so). How do i identify them?
is there any open source tool that does.

i have found one such tool http://www.codeproject.com/tools/leakfinder.asp.

After following the instructions given there, i tried to "make" my project , it says

error LNK2001: unresolved external symbol _DeInitAllocCheck
error LNK2001: unresolved external symbol _InitAllocCheck

pl do let me know if i have done any mistakes

pl kindly help me out in this problem

Thanks in advance

Regards

You can always use valgrind to find leaks and such.

But seem Valgrind is having many false alarms when used with Qt codes. Is that true?

I have never seen a false alarm by valgrind. However valgrind often alarms about constructs that are intended. For example it is not necessary to free memory, when you know that the programm is going to exit right now.
