Bug#741243: [PATCH] localedef fix on hppa architecture
Package: eglibc
Version: 2.18-4
Severity: important
Tags: patch
This command:
localedef -i de_DE -c -f ISO-8859-1 -A /usr/share/locale/locale.alias de_DE
fails on the hppa architecture because localedef wants to remap the locale file at another location than what it was given originally.
This fails on hppa, because each file must be mapped so that the same byte in a file is mapped at offset modulo SHMLBA-1.
Otherwise you will get a EINVAL error from mmap().
Dear Debian maintainer,
could you please add this patch temporarily to the debian eglibc sources?
It will take me quite some time to discuss the best approach to fix it upstream, but in the meantime it would be nice if the debian eglibc package
will not show this problem on hppa.
Thanks,
Helge
