UI issue on Ubuntu Bionic

[clangen]

First off, really cool project!

It works very well on my Arch install, but seems to have character-drawing problems on Ubuntu. Maybe specific to my setup, but I spent a few minutes looking at the code and my environment and didn't see anything obviously wrong.

Here's what I see shelled into my Ubuntu machine:

Output from locale seems reasonable:

➜ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

I also thought maybe it was some sort of Unicode character drawing issue, but I tried another terminal-based app and it seems to be rendering extended (non-Latin, UTF8) characters just fine.

For reference, here's what it looks like when I'm shelled into my Arch install:

This is because it uses ncurses without widecharacter support on Ubuntu, you can try to build it using `make distclean` then `USE_WIDE=1 make` this works on some distros. Not sure it will work on Ubuntu though.

Yep, that fixed it. Thanks! :)

Let me know if I should create a separate issue for this. I have the same issue on Gentoo with your ebuild[1] and the flag wide. What to do?

1: https://github.com/fulhax/fulhax-overlay/blob/master/media-sound/ncpamixer/ncpamixer-1.3.3.ebuild

[c0r73x]

Humm, heat kind of issue? I think I installed with that ebuild. I might have forgotten to push something though. 🤔

[Hund]

This. :/

[c0r73x]

Humm, that is odd. I even added the wide flag as default. I will check if I pushed everything.

[c0r73x]

Ah, ok.. it seems i run the 9999 version with the wide flag on. Probably the 1.3.3 tag is incorrect.

I am still having the issue of terminal not showing correctly after running make distclean and USE_WIDE=1 make respectively instead of just make.

I seem to have no issue of displaying the character since it shows the character perfectly fine in Vim.
Can you help me trace down the issue?

System: Debian 9.7.0
Terminal: st

Cloned from the master.

[c0r73x]

Did you run make distclean before running USE_WIDE=1 make?

[zatnas]

Yes, I have run make distclean to clean the build beforehand.

[c0r73x]

Did you clone from master, or is it the 1.3.3 file?

[zatnas]

I cloned it from the master

[c0r73x]

I will have to set up a vm with debian when I get home to do some testing, seems it refuses to use ncursesw for some strange reason :(

[hamsterready]

Install these:

sudo apt-get install libncursesw6 lib64ncursesw6

and when you build with USE_WIDE=1 look for something like this:

-- Looking for wsyncup in /usr/lib/x86_64-linux-gnu/libcurses.so
-- Looking for wsyncup in /usr/lib/x86_64-linux-gnu/libcurses.so - found
-- Looking for cbreak in /usr/lib/x86_64-linux-gnu/libncursesw.so
-- Looking for cbreak in /usr/lib/x86_64-linux-gnu/libncursesw.so - found

Worked for me.

Any news on this? :)

[c0r73x]

Hi, I've been quite busy and havn't got time to check on this. But from @hamsterready 's comment it seems that Ubuntu don't shipt with ncursesw by default?

Hi,
Same problem here on Slackware64-current.

With no luck.
