Crashes Ardour 8 #23

Closed derkrasseleo closed 4 months ago

derkrasseleo commented 1 year ago

When I try to load the plugin, Ardour instantly crashes with this error:

** (ardour-8.0.0:149601): ERROR **: 23:33:16.823: 
unhandled exception (type std::exception) in signal handler:
what: locale::facet::_S_create_c_locale name not valid

Other Plugins (BOops, BSchaffl) work fine..

Thanks for report. Which OS and version did you use? And which version of B.Choppr? From a third party packager or directly from this github repo?

It may be an UI toolkit related problem as it doesn't seem to happen with B.Ooops and B.Schaffl (which run with an older toolkit).

Arch Linux (6.5.8) and the package from the extra repo (bchoppr 1.12.6-1), the git package from the aur doesn't seem to build, but I'll try to install it

Now I get this error: BChoppr.lv2#GUI: Instantiation failed. locale::facet::_S_create_c_locale name not valid suil error: Failed to instantiate UI <https://www.jahnichen.de/plugins/lv2/BChoppr#gui> in /usr/local/lib/lv2/BChoppr.lv2/BChoppr_GUI.so

I still don't get a GUI, but at least it doesn't crash ardour anymore..

sjaehn commented 1 year ago

This means that the B.Choppr GUI constructor made the problem. But doesn't tell what exactly happened.

However, I failed to reproduce this problem using Ubuntu 22.04, Ardour 8.0, B.Choppr 1.12.7.

Wierd, I just installed Ardour 8 and b.choppr on a different device and it worked. I also tested reaper on my main machine and I get a similar error: jack: created client jack: non-realtime threads LC_NUMERIC / LANG is set to 'de_AT.UTF-8', overriding LC_NUMERIC environment to POSIX jack: activated client BChoppr.lv2#GUI: Instantiation failed. locale::facet::_S_create_c_locale name not valid Segmentation fault (core dumped)

Interesting, I just disabled Use Translations under Appearance -> Translation in Ardour settings, now I have a GUI again. Sorry for bothering you..

This is not really a solution - only a workaround - and a bad one since this setting is only in Ardour and effects all plugins

I also have this problem - the plugin crashes Ardour and in Carla the GUI does not show up

In both of these programs it starts working if I start them with LANG=C so the problem only occurs if it tries to load translations

Please reopen

Just want to say: In the meanwhile, I had to fully reinstall arch, and currently I'm running bchoppr-1.12.6-1 with Ardour 8.6.0 and don't experience this issue.

same

I had to fully reinstall arch

did you also delete all user files (/home partition)? because if not you still have your Ardour configuration from before which means you have disabled Use Translations and so the problem is worked around

can you also test with Carla?

Yes, full reinstall, also the GUI works in Carla

gechoto commented 4 months ago

ok so I did more testing and think I found the cause

My system is set up in a way that programs are displayed in English but only some things (like time & date format and units) are in my native language

This is just the way I prefer it because some translations in my native language aren't that great and also I use it to learn English better but at the same time I'm not a fan of the American date/time format

But BChoppr does not like this

It only works if I set the system FULLY to ONE language. So if I set everything to English and also use the am/pm 12h clock format, other currency, units... BChoppr works!

But if I set the system to be a mix of English and my native language it breaks again

Note that I have been using this mixed language setup for about 2-3 years now already and never experienced problems in other software so it is a BChoppr specific issue

gechoto commented 4 months ago

huh just to make extra sure... I reinstalled some language related packages, fully updated everything, recreated some configs also switched away from having my language settings done by the desktop environment, deleted the user-wide settings file and instead did the language settings system wide now (in /etc instead of in the home dir)

somehow it works now not sure what exactly did the trick as I did a number of things but happy to report that BChoppr works now

It still could maybe be made more robust against crashes around translation related stuff as I said BChoppr is the only software that crashed with my setup before and I had it for years like that but overall I guess this can be closed again

derkrasseleo commented 4 months ago

Doesn't seem to be related to BChoppr itself, maybe it's an issue in the B.Widgets toolkit. I'll close this now
