Description Juro Bystricky 2015-10-26 22:31:25 UTC 
Install a  buildtools-tarball such as poky-glibc-i686-buildtools-tarball-i586-buildtools-nativesdk-standalone-xxxx.sh in a non-default location.
Source the environment, i.e.:

$ . environment-setup-i686-pokysdk-linux

Run a command such as:

$ strace make 2>&1  | grep /opt

Observe:
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/lib/locale/locale-archive", O_RDONLY|O_LARGEFILE|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/share/locale/locale.alias", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/lib/locale/en_CA.UTF-8/LC_IDENTIFICATION", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/lib/locale/en_CA.utf8/LC_IDENTIFICATION", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/lib/locale/en_CA/LC_IDENTIFICATION", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/lib/locale/en.UTF-8/LC_IDENTIFICATION", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/lib/locale/en.utf8/LC_IDENTIFICATION", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/lib/locale/en/LC_IDENTIFICATION", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat64("/opt/poky/2.0/sysroots/i686-pokysdk-linux/usr/include", 0xffc768e0) = -1 ENOENT (No such file or directory)


So some files are assumed to be in default (but potentially non-existent) location.
Although this does not seem to be harmful, it should be either fixed or justified.
Comment 1 Juro Bystricky 2015-12-02 22:06:29 UTC 
The culprit seems to be libc-2.22.so, as it contains some hard-coded links that may not exist:

Comment 2 Juro Bystricky 2016-03-14 17:52:56 UTC 
Meant to say hard-coded paths (not links).
Comment 3 Richard Purdie 2018-10-11 15:16:04 UTC 
We now include locale data in the sdks and uninative so these paths are now handled correctly. If there are any remaining issues we'd handle in separate bugs.
