Why doesn't iconv know ISO-8859-2 in rawhide?

[Zdenek Dohnal]

Hi all,

vim started to fail to build today with error during compiling desktop file:

msgfmt --desktop -d . --template gvim.desktop.in -o tmp_gvim.desktop
cs.po: warning: Charset "ISO-8859-2" is not supported. msgfmt relies on 
iconv(),
                 and iconv() does not support "ISO-8859-2".
                 Installing GNU libiconv and then reinstalling GNU gettext
                 would fix this problem.
                 Continuing anyway.
msgfmt: Cannot convert from "ISO-8859-2" to "UTF-8". msgfmt relies on 
iconv(), and iconv() does not support this conversion.
make[1]: *** [Makefile:219: gvim.desktop] Error 1
make[1]: Leaving directory '/builddir/build/BUILD/vim82/src/po'
make: *** [Makefile:2154: languages] Error 2

glibc (glibc-devel, glibc-common and glibc-headers-x86) and gettext are 
in buildroot, so the advice should be applied, but still I cannot figure 
out how to fix the issue.

Would anyone mind helping me here?

Thank you in advance,

Zdenek

Hi Zdenek,

See: 
https://lists.fedoraproject.org/archives/list/[e-mail]/...

TL;DR: workaround is to manually install glibc-gconv-extra, but you 
shouldn't need to do anything really because this should already be 
fixed by having glibc depend on glibc-gconv-extra.

Thanks Michael!

Aha, it seems the rawhide buildroot from 6/23 still contained glibc with 
recommends on new package and not hard requires.

I've explicitly added glibc-gconv-extra as a buildrequires for vim now - 
although as you told it is unnecessary right now, I guess it is a good 
thing to track what the package actually needs (dependencies can change 
with time, as I found out painfully over the years :D ).

Sorry yes, we haven't done a build yet.  I expect one to come out next
week with this fix and the fix for some other breakages.

I've got a releng ticket[1] out to pull glibc-gconv-extra into the
minimal buildroot so that we can weaken the dependency again.  That
way every package won't have to explicitly mention this dependency.

Thanks,
Siddhesh
