Cannot start Carla, loadlocale.c related error

[smrg-lm]

Hi

I don't know if this is a bug but for pre-compiled Linux binaries on newer oses Carla throws:

Carla: loadlocale.c:130: _nl_intern_locale_data: Assertion `cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0]))' failed.
Aborted (core dumped)

I believe could be the same problem as here:

junegunn/fzf#350 (comment)

Emptying LANG makes it to work as suggested in the comments.

[falkTX]

so you get this issue when using the carla's pre-built binaries? (from github releases)
or do you also get the issue when using carla packages from your distro?

[smrg-lm]

I've switched to 18.04 vanilla, not using packages as they are not available yet, precompiled from here.

[falkTX]

what packages do you refer to, that are not available?
(if it's about kxstudio, it has been ready for 18.04 since a few weeks)

but ok, I will try the pre-compiled packages on a 18.04 when I get the chance.
hopefully I can reproduce it there.

[smrg-lm]

Using the .deb from the web page I saw the repo that has jack was not on bionic and it generated a dependency problem, that's why I thought it was not ready and purged it. I will try it again tomorrow. However, this locale issue with pre-compiled Carla happened out of the box in Kubuntu.

Dont want to spam, but maybe it helps. I have the same error here using precompiled version (Carla_2.0-beta6-linux64) on ubuntu 18.04.

Temporary solution

export LANG=C

[falkTX]

I built new binaries that likely resolve this issue.
Download them from https://github.com/falkTX/Carla/releases/tag/1.9.8c

Please test and let me know if they work for you, or not.
(Only relevant for those that had the issue before)

This is the last issue to be fixed for a new beta release.

Hi, I am not the original poster but I have the same issue.
I've tested your updated binaries but unfortunately no cigar. Thanks anyhow.
Cheers,
Spleenico

[falkTX]

Yeah, those binaries did nothing.
I was able to reproduce the issue, and then the fix.
New release is ready to go, I will upload binaries soon.

[Spleenico]

@falkTX
Great, thanks in advance!

[falkTX]

alright, please test with the new release binaries. at https://github.com/falkTX/Carla/releases/tag/v1.9.9
tomorrow I will try to write the release notes

[Spleenico]

Thanks Filipe,

This is what I get with Carla_2.0-beta7-linux64:

spleenico@spleenico-XPS-L322X:~/Downloads/Carla_2.0-beta7-linux64$ ./Carla
Carla self-contained executable 1.9.8 (2.0-beta6), based on UnZipSFX.
Launching: '/tmp/carla/carla'
Traceback (most recent call last):
  File "/usr/share/cx-freeze-common/initscripts/Console3.py", line 27, in <module>
  File "build-carla/src/carla", line 22, in <module>

[falkTX]

That happens when missing dependencies. I guess Qt4 libs?

[Spleenico]

Thanks to this thread: #629, I saw that python3-pyqt4 was missing.
Likely a general issue with Ubuntu 18.04.

Now Carla fires normally.
Thanks!

[falkTX]

You dont actually need python-pyqt, just Qt4.
The binaries I publish include python inside.

[smrg-lm]

I apologize, can't try it now.

I couldn't run the precompiled binary of RC2, RC1 nor beta7 on a fresh install of Ubuntu 18.04:

~/Carla_2.0-RC2-linux64$ ./Carla
Carla self-contained executable 1.9.11 (2.0-RC1), based on UnZipSFX.
Launching: '/tmp/carla/carla'

  File "build-carla/src/carla", line 22, in <module>

After I found this thread I tried to find and install the missing dependencies (as seems that Ubuntu 18.04 does not include Qt4 libraries by default). The minimal install that get Carla running is:

$ sudo apt install libqt4-svg

which also installs in my fresh system:

The following NEW packages will be installed:
  libmng2 libmysqlclient20 libqt4-dbus libqt4-declarative libqt4-network libqt4-script libqt4-sql
  libqt4-sql-mysql libqt4-svg libqt4-xml libqt4-xmlpatterns libqtcore4 libqtdbus4 libqtgui4
  mysql-common qdbus qt-at-spi qtchooser qtcore4-l10n
0 upgraded, 19 newly installed, 0 to remove and 4 not upgraded.

I wouldn't call this a Carla bug, but It is a pity that the precompiled doesn't run on new systems, specially when it is the easier way to get audio stuff working on Linux (both Carla and the tar.gz).

Is it feasible to include those dependencies into the package? Is it good idea? Now I have an AppImage Qtractor, and... mmm.... a snap calculator. What about just a notice on the README?

I love to jam on Carla. Thanks for your amazing work :)
