What
runtime error did you encounter and what host did you use?
I tried it in Ingen. With your code, when I double click plugin (to show
GUI) it reports "Failed to instantiate Plugin UI" and Ingen GUI freezes
(although, engine still runs in background).
That's interesting. Unfortunately, I couldn't get Ingen to compile on
my machine (running Arch), so I cannot test this at the moment. But I
will look out for it and compare with other LV2 GUIs. I actually
copied the code from the example in the GUI header file (forgot its
name, will check at home).
Any chance that this is a bug in Ingen? (It shouldn't crash, but I
know I'm being a little bold to pass on the origin of the crash from
my untested whacky haphazard code to a well-tested program which is
used by many more people...)
I'm pretty new to templating too and, even
though your code made some
sense,
I was comparing it to another very simple example
of LV2 GUI code (just a
button too but without MIDI support), and only difference in code (and in
crashing Ingen :)) was that line.
Thanks for your input. I hope I can get Ingen compiled and see for
myself where the problem lies.
I have found the best way to build ingen is to grab the entire svn tree (
instructions at
)and do a top level
make and make install. Installing the programs piecemeal seemed to cause
problems.
