So, since it's been a problem pending for way too long, I applied your
patch to master. I however did a change: make sure we re-use the glibc
tarball if possible. To do this:
- I defined LOCALEDEF_SOURCE = glibc-$(LOCALEDEF_VERSION).tar.gz and
HOST_LOCALEDEF_DL_SUBDIR = glibc
- I changed the hash file because the tarball is now named
glibc-<version>.tar.gz
I also wondered about making localedef.hash a symlink to glibc.hash,
but that would require updating the symlink everything the glibc
version is updated, because glibc.hash is in a version-specific folder.
Overall, I am wondering if we shouldn't give up on this host-localedef
package and in fact move this to a host-glibc package. Indeed that's
really what we're doing here: build a host-glibc package.
The only issue with doing this is the "HACK" patch. Indeed, how to make
sure this patch will apply to all glibc versions we support ?
But since the locale problem has been around for a long time, I
preferred to apply your approach now, we can always improve things
later if we think it's useful.
Best regards,
Thomas
