Re: [ecasound] LV2 Plugin Support

Okay, so I did a little more work on it. now trying to test it out.
Unfortunately, the git version of ecasound (before I make any changes to it)
is giving me...

$ echo "ladspa-register" | ecasound -c
********************************************************************************
* ecasound v2.8.1+dev (C) 1997-2011 Kai Vehmanen and others
********************************************************************************
(eca-chainsetup) Chainsetup "untitled-chainsetup"
(eca-session) NOTE: Unable to create a valid chainsetup from the
command-line arguments.
ecasound ('h' for help)> (eca-control) Registered LADSPA plugins:

ecasound ('h' for help)> ecasound ('h' for help)> ---
ecasound: Exiting...

Whereas the Debian package will list all the LADSPA plugins installed on my
system with the same command. So at this point, I am a bit troubled as to
how I can test my LV2 support, as I have nothing to compare it to.

If anyone is interested in seeing what the problem is, I have put up a git
repository of my work: https://github.com/jeremysalwen/Ecasound-LV2 the
branch "master" is just the current ecasound branch. The branch "LV2" is
the one I did work on.

You still need to modify lilvmm.hpp if you want it to compile. Just change

    const char* uri_to_path(const char* uri) { ...

to

    static const char* uri_to_path(const char* uri) {...

wherever it is installed in your system.

Also, any help with understanding why ecasound won't list the LADSPA plugins
when I build it from source would be great. (As a note, I get this error
system installed ladspa.h, or the one bundled with ecasound)
