2.0: error: Failed to open library /usr/local/lib/lv2/yoshimi.lv2/yoshimi_lv2.so (/usr/local/lib/lv2/yoshimi.lv2/yoshimi_lv2.so: Undefined symbol "argp_parse")

This happens when I try to instantiate the LV2 plugin in jalv.qt5.

OS: FreeBSD 12.2

[yurivict]

LD_PRELOAD=/usr/local/lib/libargp.so helps.

This is very strange. LV2 shouldn't be seeing argp at all!
Is it just with jalv, or do you get the same result with other hosts?
In any case, I've moved the config call further down the code (where it should have been), but I doubt it makes any difference.

[yurivict]

This is with all hosts.

[abrolag]

I'll see what I can find. Unfortunately we don't have anyone here these days with any experience of BSD so I'll be working blind :(

Ah. I remember something about this now! Have you actually installed argp-standalone? If not you need to do so.

argp-standalone is installed.
The problem is that the LV2 plugin gets linked with it when it shouldn't.

[kramlie]

While it's true that it is unnecessary to call argp inside the LV2 plugin, LV2 and the standalone binary share this code, and it is not easy to split this part with the current codebase. It's just too hard to change this without significant refactoring.

What about standalone Yoshimi, does it work without any LD_PRELOAD magic?

The latest commit to 'Master' has a small rationalisation in Config.cpp which *might* make separating the apgp code a bit easier - not sure though.

There is now a provisional fix for the whole problem in the current build. It's a sledgehammer approach. I copied Config.cpp and Config.h across to the LV2 code section, commented out all the argp bits and redirected the LV2 CMakeLists.txt file It works correctly on Linux, but can you check in BSD in case there are bits I missed.

We'll try that again :( For some reason it failed to include the Config files, but gave no indication of the fact :(

The problem is gone in 2.0.1.

Thank you.
