Carla: 'PyQt5' missing?

Postby LinMusGuy » Mon Jun 17, 2019 10:38 am

I want to try Carla on my 32-bit Linux Mint computer but I get the error message:

Code: Select all

Traceback (most recent call last):
  File "/usr/share/carla/carla", line 22, in <module>
    from carla_host import *
  File "/usr/share/carla/carla_host.py", line 24, in <module>
    from PyQt5.Qt import PYQT_VERSION
ImportError: No module named 'PyQt5'


Is Carla no longer supported for 32-bit?

I think that the developer of KXStudio/Carla will reply himself. But for now: what version of Mint are you using (i.e. on what Ubuntu version is it based?). Are you using the KXStudio repository? What version of Carla are you using (i.e. the git or the alpha version)? There are recent developments in Carla you might want to check, see: https://kx.studio/News/

Good luck! :)

Thanks. :)

Strange enough looking at the Carla programs in the repository I just now found out that one Carla program that I thought I had installed was not actually installed, so I did it again. Now I can open two Carla programs by means of the icons on my desktop. :D

Next I will see whether I can also run VST's in Carla...

It works! :D

Except that some nice plugins don't show their GUI in Carla... :( Is there a solution for that problem?

Depends on the VST. Some work, some don't. Some might work better w/ LinVST than w/ Carla. Which VST does not show it's GUI?

I just now tried some other VST's in Carla and they all worked perfectly (including showing their GUI's).

So overall it's a great program! :D

Has LinVST some options that Carla doesn't (and does it run on a 32-bit system)?

See my post here about my experiences w/ LinVST, Carla etc. Summary for LinVST:

  • LinVST compilation went well on my old Mint 17.1 machine (there's also a Zip file w/ precompiled binaries for modern Debain based systems). Just remember to rename the file "Makefile-embed-6432" to "Makefile", else: no 32 bit support. You also have to install the so called multilib versions of gcc and g++ for 32 bit support.
  • LinVST bridged 32 bit Windows VST's work fine in a lot of DAW's but not in Qtractor, alas. The knobs of your virtual synths turn around like crazy and buttons go on and off 10.000 times a second.
  • LinVST bridged 64 bit VST's on the other hand work fine in Qtractor.

Dunno if LinVST runs on a 32 bit system, but it sure has some caveats for 32 bit Windows VSTS!

Thanks - I'll stay with Carla then.
