Linking with JACK 0.124.1: undefined reference to jack_set_port_rename_callback

[diogocp]

Still having trouble with JACK. Now it's a linker error.

Scanning dependencies of target backend_disconnect_recover

libsoundio.so.1.0.0: undefined reference to `jack_set_port_rename_callback'
collect2: error: ld returned 1 exit status

I suppose this is the problem:

$ nm -D /usr/lib/libjack.so | grep jack_set_port
000000000000b820 T jack_set_port_connect_callback
000000000000b7a0 T jack_set_port_registration_callback

No rename. JACK bug?

With JACK2 1.9.10:

$ nm -D /usr/lib/libjack.so | grep jack_set_port
000000000000dc70 T jack_set_port_connect_callback
000000000000dc20 T jack_set_port_registration_callback
000000000000dcc0 T jack_set_port_rename_callback

Here's the API spec:

http://jackaudio.org/api/group__ClientCallbacks.html#ga0c73095c1d8ebba413de6834bd7757b9

It does say JACK_OPTIONAL_WEAK_EXPORT though I don't see an explanation of what that means.

However, libsoundio needs this functionality, so if jack1 doesn't support it then libsoundio doesn't support jack1. Here is the issue tracker: https://github.com/jackaudio/jack1 - I don't even see an issue mentioning this.

Found a recent commit adding it: jackaudio/jack1@0ac9ef7. Unfortunately it hasn't been released yet. :(

Closing since it was fixed upstream.

Fixed in jack1 0.125.0.
