GRSecurity releated?

[To]

I've having problems copiling wxGTK and wxWidgets on gentoo. This is the only 2 packages that fail to copile and I'm start to think that may be some grsecurity feature that I've may turn on that make s this happends:

Code: Select all

The bug is not reproducible, so it is likely a hardware or OS problem.

Any ideas? I don't have any kernel without grsecurity, but I can copile one and give it a try...

I've having problems copiling wxGTK and wxWidgets on gentoo. This is the only 2 packages that fail to copile and I'm start to think that may be some grsecurity feature that I've may turn on that make s this happends:

precompiled header support (PCH) is not compatible with ASLR, or rather, there's a botched up attempt at handling it but it's not compatible with SEGMEXEC, so your best option is to disable everything on the gcc binaries: paxctl -rspm /usr/bin/i686-pc-linux-gnu* /usr/i686-pc-linux-gnu/gcc-bin/*/i686-pc-linux-gnu* /usr/libexec/gcc/i686-pc-linux-gnu/*/*

if you have softmode, you could enable it while emerging these packages as well.
