[gentoo-user] mc-4.6.1 not showing graphical characters in terminal

[gentoo-user] mc-4.6.1 not showing graphical characters in terminal

[Peter]

After
1) upgrade to gcc 4.1.1
2) upgrade to profile 2006.1
3) revdep-rebuild recompile for libstdc++ and for new profile uses (which
included mc)

Now, issuing mc at a terminal prompt (not inside X) shows no border
characters. Does this have something to do with unicode support? The only
way I can get any useful terminal output is to use the -a output for stick
characters. Inside an xterm or similar, mc shows graphical characters
fine. I re-emerged mc with -unicode, but the results are the same.

Emerge mc with slang use-flag and you'll be fine ... I put put mine 
globally in /etc/make.conf but you may consider to use 
/etc/portage/package.use as well.

Yup...

I had the same MC issue after upgrading to the 2006.1 levels. It's a very 
basic language issue. I'm not sure if it's gcc, glibc or perhaps an xorg 
module...

Prior to this upgrade, I never gave language setting a second thought... but 
once mc began acting up, I started digging around with google and this is 
what I cobbled up.

In "/etc/env.d/02locale " I have set: LC_ALL="en_US.ISO-8859-1"
In "/etc/rc.conf" I set "UNICODE=no"
In "/etc/conf.d/consolefont" I have set: CONSOLETRANSLATION=8859-1_to_UNI"

That last line makes no since to me, but it seems to be required for MC.

Last but least run env-update, source /etc/profile and check /etc/profile.env 
has LC_ALL set to "en_US.ISO-8859-1". It may take a reboot, but once I had 
made the change, midnight commander began drawing lines again.

The only other problems I ever had with MC is, if I leave mc running for any 
length of time, it begins to take more and more cpu resource... Top will show 
like 80% useage. Once I kill off mc, everything is back to normal. Anyone 
have a tip for that one?

Jerry...

P.S. I welcome all comments.

This is tough. I filed a bug. Obviously, with unicode a new can of worms
has been opened. I have slang, ncurses, etc. I did not change the default
console fonts but am afraid I will have to. ITMT, mc -a will have to do.
Thanks for the feedback. Feel free to chime in on the bug. Jakub is in his
worksforme mode.

Hi Peter,

I just had a look at the bug report and comment #5 from Jakub Moc is the 
correct fix. 

I'll chime in and post my thoughts anyway...

For over two years, I took LC_* for granted. Never touched it, never
looked at it (snobbery of being en_US I suppose!). Now, with the 2006.1
profile, I am forced to learn an essential part of Linux. So now, I am set
with en_US and ISO8895-15 although I still don't know where the 02locale
file should have been set from. I manually created it.

Interestingly, there are some problems with the line drawing characters.
In particular
1) the vertical lines don't meet the horizontal ones to make a T or
inverted T. They just stop short and the character for joining the two is
not drawn
2) At the right, just before the corner, there is a v>
3) At the right vertical line, where the horizontal should meet line --|
there is a gap and the vertical is interrupted and the character to make
that join is not drawn.
        |
---------
        |

However, all this is much better than before, and I don't do that much
with mc in a terminal anyway. As I noted, it's fine under any X.

Thanks again for your help.

I added a documentation bug, see bug #147062, to request they add a note
somewhere about checking localization. Thanks again for your help!

This is not connected to your profile or gcc upgrade. It's your glibc upgrade. 
glibc-2.4.x is stricter when it comes to syntax than glibc-2.3.x. Please show 
the output of:

# grep -v '^$\|^#' /etc/locale.gen
# locale -a
# locale

Also utf8 isn't the default in Gentoo (yet). /etc/env.d/03locale should have 
been created manually when you followed [1] given that you wanted utf8.

I think that its enought to turn off UNICODE in /etc/rc.conf to restore
previous behaviour (2006.1 has it turned on by default). With it
terminal is set to unicode and that causes problems I suppose.

Locale (C as default) and translation shouldn't be required. If you want
to have proper frames displaying with unicode do the following:

UNICODE=yes in /etc/rc.conf
CONSOLEFONT="LatArCyrHeb-16" in /etc/conf.d/consolefont
	drdos8x16 migth do the trick as well

for latin1:
LC_[ALL|CTYPE]=en_US.UTF-8 (or any other language) in /etc/env.d/02locale
	you need to add this locale to /etc/locale.gen and regenerate
	locales	with locale-gen
CONSOLETRANSLATION=8859-1_to_UNI in /etc/conf.d/consolefont
DUMPKEYS_CHARSET="iso-8859-1" in /etc/conf.d/keymaps
for latin2:

LC_[ALL|CTYPE]=pl_PL.UTF-8 (same trick as above, and pl_PL is in my case)
CONSOLETRANSLATION=8859-2_to_UNI in /etc/conf.d/consolefont
DUMPKEYS_CHARSET="iso-8859-2" in /etc/conf.d/keymaps

Reboot might be required, dont know if its enough to restart consolefont
and keymaps services.

Make sure you have mc compiled with unicode and slang USE. This way you
should have properly configured unicode console support (as for some
reason 2006.1 tends to set). Beware though that not all applications
work properly with it. Mc and vim f.e. does.

I don't have an 03locale file. I manually created an 02locale file.

Over here they match up perfectly... Which console font do you use? I prefer 
TERMINUS

Your emerge --info shows that you are using glibc-2.4 on an x86 stable system. 
glibc-2.4 and gcc-4.1.1 was stabilized at the exact same time (11 days ago) 
so until I see proof of the opposite I am going to assume that glibc was 
upgraded when you recompiled with gcc-4.1.1.

If you still think glibc wasn't upgraded at the same time then please emerge 
app-portage/genlop and show the output of:

# genlop sys-libs/glibc
# genlop sys-devel/gcc

> > # grep -v '^$\|^#' /etc/locale.gen

So you obviously don't want utf8. Otherwise you should add a utf8 locale to 
locale.gen and follow the utf8 guide. Syntax is correct btw... As long as you 
don't want unicode.

That was a typo. I meant 02locale. Not that it really matters though...

AFAICT the real issue, however, seems to be the fact that sys-apps/baselayout 
has this code in the ebuild:

src_unpack() {
	[...]
