[gentoo-embedded] uclibc + glib 2 - possible?

[gentoo-embedded] uclibc + glib 2 - possible?

[Ed W]

Does anyone have any suggestions to getting glib 2.6 or newer to build 
against uclibc 0.9.30.1 (or similar)?

The docs claim it's masked because glib 2.6 and newer require iconv, 
which is increasingly unavailable on newer uclibc builds...

Actually I don't need locales, I just want to build gpsd to use dbus, 
and that appears to require a recent glib ...  Any suggestions?

Thanks

yes, there is a hack on bugs gentoo org  , bug #104468 . it seems like
not much is happening with this bug, unfortunately :/

Hmm, interesting - patch seems clean - will try it shortly.  Anyone 
tried it on a more recent glib and can point out any issues before I 
spend too much time on it?

Thanks

How do you override profile/packages ...??

I tried adding an entries to
/etc/portage/package.unmask
/etc/portage/profiles/package.unmask
/etc/portage/profile/packages (added just *dev-libs/glib - is this right?)

Still glib says it's profile masked??!!

Thanks

OK, progress so far:

These patches allows glib to build:
    http://bugs.gentoo.org/show_bug.cgi?id=104468
    http://bugs.gentoo.org/show_bug.cgi?id=268647

You need to unmask it by appending to /etc/portage/profiles/packages:
    -<dev-libs/glib-2.5


However, then dbus-glib fails to build (which was my original goal) with 
an error about lacking gettext.  I patched this test out and it then 
falls over


 i386-gentoo-linux-uclibc-gcc -DHAVE_CONFIG_H -I. -I.. -I.. -I.. 
-I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -I/usr/include/glib-

: libintl.h: No such file or directory
make[4]: *** [dbus-glib.lo] Error 1



I guess I need to fix this to get it going, but wondered if anyone had 
any experience?

I see that uclibc recent builds have a "locale" option which isn't 
enabled by default.  I'm still baffled by the relationship between 
"locales", gettext and iconv.  Does it help or hinder my cause to be 
looking at enabling locales in uclibc?  (I have minimal needs for non 
english charactersets right now)

Thanks for any pointers
