Search plugins "permission denied" in Ubuntu 22.04

[JRSV]

Hello

I am running into a problem and cannot figure put how to fix it. When I search directories, I get a "permission denied". I have tried copying plugins to other directories that I am certain to have permission.

I am running Ubuntu 22.04, pd 0.54.1 and latest deken release of vstplugin~

any ideas how can I fix this?

What are the permission of the host executable? Also, please post the output of the Pd console.

Ok, sorry for the delay, I decided to do a fresh install of AVLinux, hoping to solve. Unfortunately it is not an OS problem. Previous versions of vstplugin~ worked with no issue.

to your questions,

permissions for host executable are read write, I did encounter the contrary though so I made sure the plugins were "owned" by me. The Pd window keeps saying the contrary, I get "permission Denied [13]"

probing '/home/jrsv/.vst/AllGVSTLinux64Beta/GBand.so'... error! couldn't run subprocess host: Permission denied [13] vstplugin~: can't open '/home/jrsv/.vst/AllGVSTLinux64Beta/GBand.so' print: open 0

I will try to test the previous version of [vstplugin~] to see if the problem is in the update.

any ideas?

cheers

It must also be executable!

couldn't run subprocess host: Permission denied [13]

Yeah, looks like host is not executable for some reason... Do chmod 755 host and try again.

ok, so I am really puzzled, I do not understand what is going on, I even tried the most extreme which was to make RWX for everyone. I changed ownership and group from root to my user

however I still cannot load the plugins and Pd window gives me the same error

any ideas??

There was a misunderstanding. I have been talking about the permissions of the host executable (next to vstplugin~.pd_linux), not about the plugins! (The plugins don't need to be executable.)

Please post the permissions of the host executable.

Ok!!! now I got something. Ran into a little problem though, I have a plugin called VASTvaporizer2.vst3, which is not loading as the Pd window is stuck in waiting for '/usr/lib/vst3/VASTvaporizer2.vst3 it does not black list it or anything and continues even if I close the patch. Is there a way to exclude this plugin? or do I have to move it?

Yes! Check the -x flag for the [search( message. Alternatively, you can also set a probe timeout with the -t flag.

The remaining question is how you ended up with a non-executable host binary. When I download vstplugin~-v0.6-pre1 here on Debian, host has the correct permissions (rwxr-xr-x). In fact, I know a few Linux users who have been testing the release and nobody had permission problems.

[JRSV]

I know!!! I decided to check what happened, I suspect this happened when I reinstalled my OS to theDebian machine I mentioned, as I checked the version and it was V. 0.5.1. I have now downloaded it again from Deken and v-0.6 is up and correctly running. Either way it was good to understand permissions and ownerships for the host executables. Sorry for the noise... and thanks for this object

You're welcome!
