Ubuntu, Ardour, KXStudios: old problem, new flavour

[sjaehn]

I'm one of the Ubuntu 18.04 / KxStudios / Ardour 5.12 users who can't get the VeeOne plugins running in their DAW.

I just updated from 0.9.2 where the GUI didn't work to 0.9.11.

In 0.9.2 I got the message:
suil error: Unable to open UI library /usr/lib/lv2/samplv1.lv2/samplv1_ui.so (/usr/lib/x86_64-linux-gnu/libQt5Gui.so.5: undefined symbol: hb_font_funcs_set_nominal_glyph_func)

In 0.9.11 I get the same message now from lilv:
lilv_lib_open(): error: Failed to open library /usr/lib/lv2/samplv1.lv2/samplv1.so (/usr/lib/x86_64-linux-gnu/libQt5Gui.so.5: undefined symbol: hb_font_funcs_set_nominal_glyph_func)

And this prevents Ardour even to start the plugin DSP.

In jalv everything is fine. With the notable exception of a segfault I observed.

long known problem.

workarounds:

1. build your own ardour 5.12 over the ubuntu 18.04 (bionic) system libraries;
2. build the vee-ones against the qtbase5-static libraries;
3. update the kxstudio repos and install any of vee-ones(-lv2) from there; OR
4. add one of my own Launchpad PPA's to your apt sources; eg.:

sudo add-apt-repository ppa:rncbc/bionic
sudo apt-get update
sudo apt-get install samplv1-lv2

Note that either 3) and 4) do provide the same result as if route 2) is taken; though 4) will end with the very latest and greatest snapshots from yours truly upstream. Remember to uninstall first any existing or previously installed vee-one that you have around (esp. if you built before from source and possibly are deployed under /usr/local/lib/lv2/...?).

hth.
cheers
