[SOLVED] Locale not supported by C library

ryoko · 02-26-2021, 06:31 PM

Hi.
I am using Slackware 14.2 with xfce. Everything was working fine, until i tried to update system.
Now i have problem with locale. i can't save files with non latin characters. The warning i get is
Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale.
I changed /etc/profile.d/lang.sh to have
export LANG=el_GR.utf8
export LC_COLLATE=C
but nothing changed.
When i type locale, i get: Cannot set LC_ALL to default locale.

Any help?

Thank you.

Not sure how Slack is set up but here's what I do. In file /etc/locale.gen in Debian are pretty much every locale, all of which are commented out except the locale for my region. In Gentoo, all it had was "C.UTF8 UTF-8", so I added "en_US.UTF-8 UTF-8" and my locale. After saving the file with the locales I want keeping the C locale also, I ran a couple commands to set the locale.
Below are the locales I found in Debian to match yours:

Quote:

el_GR ISO-8859-7
el_GR.UTF-8 UTF-8
el_GR@euro ISO-8859-7

Add or uncomment the ones you want your system to have/use in /etc/locale.gen, after saving the /etc/local.gen file, as root or sudo run command ----> locale-gen
It will come back saying it found the locales you enabled printing them out, now set the locale with the next command:

Code:

localectl set-locale el_GR.UTF-8

It should now be set and should be shown in /etc/locale.conf or /etc/default/locale
Other examples here.

Thanks for the reply. Unfortunately these don't work on Slackware. I believe something is messed real bad after the update. I read in the forum that someone with a similar problem had noticed that
/lib64/ld-linux-x86-64.so.2 -> ld-2.29.so
instead of
/lib64/ld-linux-x86-64.so.2 -> ld-2.23.so
He said that upgradepkg glibc-solibs-2.23-x86_64-4_slack14.2.txz took care of that.
In my case /lib64/ld-linux-x86-64.so.2 -> ld-2.27.so
and i also have a ld-2.23.so in the same folder.
I tried to do the same thing and upgradepkg but nothing.
i don't understand how this works, or if it has to anything with the locale problem.
I may be wrong with this.

How did you upgrade ? 14.2 has glibc 2.23 and current 2.33 so your actual libs look strange.

I must have broken sth.
If i type
ldd --version
i get
ldd (GNU libc) 2.23
then
ldd `which ls` | grep libc
i get
libcap.so.2 => /lib64/libcap.so.2 (0x00007fb99b69d000)
libc.so.6 => /lib64/libc.so.6 (0x00007fb99b2b3000)
and finally
/lib64/libc.so.6
i get
GNU C Library (GNU libc) stable release version 2.27.

Could this be the cause of locale problems? Is it something repairable?

Yes, looks like something is wrong on your system.

I'm running a fully-patched 14.2 (with multilib), and here is what I get:

I would think:

Code:

upgradepkg --reinstall glibc-*.txz

should do the trick.

Where you first cd into the directory where the proper glibc packages are (stock glibc packages or alien's multilib packages).

Petri Kaukasoina · 02-27-2021, 01:33 PM

Why don't you tell us what you did when you upgraded?

The locale stuff is in package glibc-i18n-2.23-x86_64-4_slack14.2.

Try these two commands. What is the output?

Code:

ryoko · 02-27-2021, 02:29 PM

I also tried
upgradepkg --reinstall glibc-*.txz

Nothing changed

Petri Kaukasoina · 02-27-2021, 02:54 PM

Ok, you have installed either glibc-solibs-2.27-x86_64-4 or glibc-2.27-x86_64-4, or both (or the corresponding multilib packages). And then reinstalled the correct 2.23. Unfortunately, glibc is not "downgradeable" to 2.23. After and including glibc-2.27, the glibc install script also allows downgrading but not before 2.27. Where did you get that glibc-2.27 ?

It is possible to go back to 2.23, like this:

Code:

cd /lib64
sln ld-2.23.so ld-linux-x86-64.so.2
sln libc-2.23.so libc.so.6
sln libdl-2.23.so libdl.so.2
sln libBrokenLocale-2.23.so libBrokenLocale.so.1
sln libanl-2.23.so libanl.so.1
sln libcidn-2.23.so libcidn.so.1
sln libcrypt-2.23.so libcrypt.so.1
sln libm-2.23.so libm.so.6
sln libmvec-2.23.so libmvec.so.1
sln libnsl-2.23.so libnsl.so.1
sln libnss_compat-2.23.so libnss_compat.so.2
sln libnss_db-2.23.so libnss_db.so.2
sln libnss_dns-2.23.so libnss_dns.so.2
sln libnss_files-2.23.so libnss_files.so.2
sln libnss_hesiod-2.23.so libnss_hesiod.so.2
sln libnss_nis-2.23.so libnss_nis.so.2
sln libnss_nisplus-2.23.so libnss_nisplus.so.2
sln libpthread-2.23.so libpthread.so.0
sln libresolv-2.23.so libresolv.so.2
sln librt-2.23.so librt.so.1
sln libutil-2.23.so libutil.so.1
rm -f l*-2.27*
ldconfig

(Do it in console, do not run X etc... Maybe copy these commands to a script and run it.)

ryoko · 02-27-2021, 03:35 PM

In console, i did everything you said and now...
all problems solved.
Locale back to normal.GNU C Library also 2.23.

Thank you very very much!
