How to detect memory leaks

hitesh

hi,

i have create an application for Symbian device.
i am using Qt Creator 2.2.1.
target device is "N95 8GB". i am using TRK.
there is no any analysis tool.

i want to detect memory leak in my application.
how i can detect it.

At some time someone is bound to mention one tool here. I will do this now, to save time :) use Valgrind.

hitesh

from where i can download Valgrind for Qt Creatore 2.2.1 &
which will support TRK.

Google is your friend. Notice that a memory leak is not likely to be dependent on your target platform.

By TRK you mean "Trinity Rescue Kit":http://trinityhome.org/? If so, I have no idea, but it seems to be based on Mandriva, which means it might have RPM installed. Therefore, you can try installing one of "these":http://rpmfind.net/linux/rpm2html/search.php?query=valgrind.

We have a collection of tools on the wiki page "Tools for Profiling and Memory Checking":/wiki/Profiling-and-Memory-Checking-Tools

I was referring to this post of Volker:

Hey, we spent a lot of time adding Valgrind support to Qt Creator, now let's use it :-)

I edited the page to mention that Qt Creator comes with built-in support for memory checking and profiling with Valgrind on Linux and Mac. The situation looks more bleak on Windows, but that is a different problem.

andre

I would agree, if the situation wasn't that bleak on Windows or the opening poster wasn't on a Windows system. As it turns out, he is, so although Valgrind integration in Creator is cool, it is useless in this case:

I was referring to the fact that the wiki page did not mention that Valgrind can be used directly from within Qt Creator on the platforms that support it.

Ah, right, good point, and thanks for the addition.
