[Solved] Guitarix 0.44.1 does not compile on KDE Neon 22.04

[RockVice77]

I am struggling to compile Guitarix on KDE Neon 22.04 (based on Ubuntu 22.04)
The command ./waf configure seems succesful, but during the build process I get this error:

Code: Select all

Waf: Leaving directory `/home/rock/Programs/guitarix-0.44.1/build'

I cannot understand if I am missing something or if I am using an uncompatible library.
Is there anyone that can help me to figure out the issue?

Thank you for any hint or support!

Hola,

what is the output of

Code: Select all

apt-cache policy lv2-dev

?

Thank you for your help, @novalix .

This is the output from the terminal:

Code: Select all

I had a similar problem before:

Upgrading from ubuntu's 1.16 to kx's 1.18 removes the usr/include/lv2/lv2plug.in folder. It just contains symlinks to targets inside /usr/lib/lv2/. Reinstating that folder manually may work. (downgrade to 1.16 /copy folder/upgrade to 1.18/copy folder back)

Try the Ubuntu version of the package.
It's possible that @falktx version is .. erm .. somewhat ahead of the time.

I also had the same problem a while ago with KX lv2-dev in Debian Bullseye. Fixed by removing the KX version and installing the Debian version, then using

Code: Select all

apt-mark hold lv2-dev

to ensure the Debian version remains. Same issue with the sordi package in case you ever need that for compiling.
KX has the annoying habit of using a higher epoch than distro versions to give them preference over distro-supplied versions.

I disabled the Kxstudio repositories and then I had to reinstall lv2-dev, liblilv-dev and libsratom-dev from the official Ubuntu repository.
After that I was able to build succesfully Guitarix from source code.

Thank you all for the answers!

Nice to hear that it worked out.
If you would want to readd the kxstudio repos someday be sure to ether mark the packages you don't want to be "updated" on hold (like in @sunrats example) or (better) to pin them down.

Btw: If one wants to use an up to date version of lv2-dev (1.18.10) on debian/ubuntu and derivates. This is now available in the corresponding unstable repos (should be installable on stable, too). There has been a small bug in the packaging, which prevented the package from being updated. That is resolved now.

hi everyone,

I was struggling with this very same problem and I finally fixed it thanks to this post.
I think this post should be a must read for anyone using guitarix on a debian based machine.

Thank you!
