Hi all, When compiling with 'GR_CLIENT=leak_detector', occurs An ERR: (1)What I do: after start target VM,then do the following steps in Host machine: { make env python scripts/slowload.py --symbols --remote make detach KERNEL=1 make wrappers KERNEL=1 make clean KERNEL=1 make all KERNEL=1 KERNEL_DIR=~/linux-3.8 GR_CLIENT=leak_detector }

make: *\ [/home/renzhen/granary/bin/granary/attach.o] ERR 1 }

I looked attach.cc,where clients/instrument.h is included. Did I make things in wrong steps, or other missing?

Thanks in advance :)

Seemingly, there is no 'leak_checker' implementation code. I want to make a really simple heap memory leak checker client using hashtable firstly, for example, just to check kmalloc and kfree.

I am just not clear about What is the framework that should be followed and what should be implemented.

Could you give me some advance about? (1). what's a good steps to do things? (2). and which API and DataStructure that does matters which I can use directly, and what others things should be do myself.

Thanks in advance:)

I removed the leak_detector tool some time ago, as there were quite a few changes in Granary that made it not work, and because it wasn't being actively maintained. Here's a version with the tool still in:

Hi pgoodman, The code link can be visited online, but I do't know how to download or do some git-command in my granary repo.

Thank you. :smile:
