Re: Look at valgrind
The SDK should support clang under Linux today. (I haven't tested it on Linux directly, but it has been used on MacOS, iOS, and Android as well as Windows. Might support gcc too. YMMV. If you do encounter any problems, just give me a shout through the contact page on the website and I'll see what I can do to help out.)
So as long as you have a Windows PC you can profile directly from Linux over TCP, or profile to a file and load it on Windows later. I have a friend at Facebook who says they'd be interested in using it too, but they want a Mac port. If I can port it to one other platform, the third will be more straight forward.
It's something I'm slowly working towards doing, but obviously life and real work gets in the way far too often these days, it seems. The main profiler engine and support libraries are fully separated out from the UI already, so it's really just a question of getting those building under clang - partially done already - and finding a UI solution I'm happy with.
