Hi, when running emerge python command, I'm getting the error presented below.

The error most probably occurs due to incorrect PaX settings, but I'm not sure how to convince the build system to actually compile the program. I've found a couple of threads with the same problem, but they didn't come to a solution: one user rebooted the system into non-hardened kernel with PaX disabled and recompiled the packages there.

I would like to come to the root of the problem and fix this.

Any ideas are appreciated.

for whatever it's worth, the program compiled just fine, it's just failing on the install for whatever reason. I'd tail your dmesg output right after it fails, see what that info can tell you.
just out of curiosity, are you running a 3.12 kernel? 3.12.6 gave me some real shit when I first ran it, and it turned out to be something with python and newer mprotect behaviors. I had to turn PAX_CONFIG_MPROTECT_COMPAT on in the kernel in order to get python at least functional. Firefox has been giving me similar problems too (failing on the install because of xpcom and an mprotect setting). mprotect is nothing to scoff at either, it basically makes sure memory mappings can't be both writable and executable (for obvious reasons)

Hi,

I'm running 3.10.1 kernel. I've enabled CONFIG_PAX_MPROTECT_COMPAT=y in the kernel, but Python still won't install. The same problem arises.
