grsecurity forums

I applied grsecurity-2.1.9-2.4.33-rc2-200607111636 to 2.4.33 and everything was fine (no fuzz, the only reject was the Makefile). When I compile it, I get this error:

Code: Select all

This is on debian stable. Any ideas?

oops, around line 62 in mmx.c change the %2 into %%eax and it should be fine.

patching the actual 2.4.33 doesnt works for me.

Got this message:

Perhaps you used the wrong -p or --strip option?

It's fixed in the 2.4.33 patch on the website; just use that.
