[Barrelfish-users] Compiling barrelfish without -O2?

[Patrik Eklöf]

I can confirm that I got it working (finally)! :)
The patch was the last component I needed to make it work.

So, to sum up what I had to do:
Manually compile dispatch.c by changing -fno-omit-framepointer to -fomit-framepointer.
Apply libc patch.
Fix compile error in usr/skb/testapps/cryptotest.c by finding the "tmp = tmp;" line and initializing it to NULL. It might be possible to just remove the line, but I did not test that.

I've looked a bit more on that and indeed it is a regression from the
libc change. I'm attaching a patch of this, which will be part of our
next release.

I wasn't able to reproduce the problem with dispatch.c, though.

cheers,
