Bug 158412 – glibc-2.5 does not work on arm with linuxthreads

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Erwann HOUZAY 2006-12-17 16:05:03 UTC]

Hi every body,

I'm trying to build the crossdev environnement for arm-unknown-linux-gnu using the prc-tools and crossdev --t arm-unknown-linux-gnu to compile the linux4palm kernel

I had an error with glibc....

I don't exactly know what happen, I've tried to follow up but without success...

Here the result of crossdev --t arm-unknown-linux-gnu when compiling glic.

i dont plan on fixing this ... force nptl/nptlonly

Euh... I've tried to do so using USE flags but I can't manage to get them works...

I'm not an expert...

I've tried the following. What's wrong?????




USE="nptl nptlonly" emerge -pv cross-arm-unknown-linux-gnu/glibc
hese are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] cross-arm-unknown-linux-gnu/glibc-2.5  USE="nls -build -glibc-compat20 -glibc-omitfp -hardened (-multilib) (-nptl) (-nptlonly) -profile (-selinux)" 0 kB [1]

unfortunately you just hit one of the limitations in portage

your host profile is masking the nptl flags
