valgrind

I've installed valgrind for android and I can confirm it is working as I tried running ls with it, and it works fine. But how do I execute an android app with a native component I would like to debug? I looked at this question: How to start an android app with valgrind but I have no idea how to follow it. How do you wrap an app in a shell script? What is "wrap." followed by the package name supposed to be? I tried doing this with com.matthewmitchell.wakeifyplus being my application package: setprop wrap.com.matthewmitchell.wakeifyplus "logwrapper /data/local/valgrind" but it says "could not

When I run valgrind --leak-check=yes on a program, a few bytes of lost memory are reported. Is it possible to view the contents of this memory (i.e. dump the data that is stored in it)? You can do that with the last version of Valgrind (3.8.1): Start your executable activating the gdbserver at startup: valgrind --vgdb-error=0 ....<your program> Then in another window, connect a gdb to Valgrind (following the indications given by Valgrind). Then put a breakpoint at a relevant place (e.g. at the end of main) and use the gdb continue command till the breakpoint is reached. Then do a leak search

I would like it to be easy to use. Preferably one that doesn't overwrite new(), delete(), malloc() or free(). Something like GDB if its gonna be in the command line, but I don't remember that being used for detecting memory leaks. If there is a unit testing framework which does this automatically, that would be great. This question is similar to other questions (such as Memory

I am completely lost from there, and have no idea how to build it. I do not know ANY terminal/console commands and am generally new to programming, so I have no idea how to "build" or "compile" it. I just have a folder called Valgrind with a bunch of random files in it. Could someone please tell me how to proceed? I already checked the website/documentation but it didn't really give me installation instructions, just usage instructions. Thanks PS: I know I

I would really appreciate some advice. Just for context, this is Ubuntu 13.10, python 2.7.5+, and valgrind 3.8.1. As per recommendation from Readme.valgrind I did the following. 1) Downloaded the python source with sudo apt-get build-dep python2.7 apt-get source python2.7 2) Applied the code patch, i.e. "Uncomment Py_USING_MEMORY_DEBUGGER in Objects/obmalloc.c". 3) Applied the suppression patch, i.e. "Uncomment the lines
