QLC and OLA

[Chris Moses]

Hello,

Sorry to keep bringing this up, but I cannot get any of the new versions of QLC+ to load. They keep crashing when trying to load OLA, and I don't think it's installed anymore. I used "sudo port uninstall ola" loads of times but QLC+ keeps thinking it's installed.

Are there any other files I can remove to fix this? It's really annoying Deleting the PLIST file does not work either. Here is the crash log...

Hmmmm, interesting... if I go into the App Contents and delete the following file...

/Applications/QLC+.app/Contents/Plugins/libolaio.dylib

...QLC+ then loads. I guess that's because I manually removed the plugin?

Hello Chris, when I built QLC+ 4.7.3 I double checked the OLA issue.
If I remove OLA through macports, QLC+ starts up correctly.

I fear there's a problem with OLA and macports. When I checked my installation, it seemed there were either OLA 0.8.33 and 0.9.0 installed.
I had to manually specify both versions to uninstall everything, like this:

sudo port uninstall ola @0.8.33
sudo port uninstall ola @0.9.0

In any case you can check if OLA is still in your system by typing this from a terminal:
olad -v

If it gives you an output, it means OLA is still there and you need to play with macports to remove/update it.

Hi Massimo,

It does indeed look like a Macports problem. I cannot uninstall OLA using any od the commands you mention. I tried...

olad -v

...and it showed...

OLA olad version: 0.9.0

...so I then tried...

sudo port uninstall ola @0.9.0

,,,which didn't really do anything. Typing "olad -v" again, showed the same version as before. Do you think OLA has been installed another way? I can't remember if I built OLA originally from source... how could I uninstall OLA manually, without using MacPorts?
