I have been trying to install Argotlunar and Hypercyclic as Ardour plugins without success. I keep getting there errors:
[ERROR]: LADSPA: module "/usr/lib/ladspa/argotlunar.so" has no descriptor function. [ERROR]: 'ladspa_descriptor': /usr/lib/ladspa/argotlunar.so: undefined symbol: ladspa_descriptor [ERROR]: LADSPA: module "/usr/lib/ladspa/hypercyclic.so" has no descriptor function. [ERROR]: 'ladspa_descriptor': /usr/lib/ladspa/hypercyclic.so: undefined symbol: ladspa_descriptor
The .so files are under /usr/lib/ladspa along with the other ones (I am on Ubuntu 18,04) but every time I make Ardour scan for plugins I get the error above.
Weirdly, I am able to launch Hypercyclic with their executable, just not with Ardour.
