Right, I guess I should explain what I've committed so far. I've
rolled a few of the LADSPA plugins into our build system (using scons
properly) to save us the headaches of building the plugins on all the
different platforms. It'll save people a lot of trouble. Right now the
plugins don't get installed on Linux, so Linux people will still need
whatever LADSPA package their distro supplies. I suspect this will
probably need to change (so that we install the LADSPA plugins
ourselves on Linux) because we can't count on there being any
consistency whatsoever in the LADSPA packages across various Linux
distros (yay for Linux). And if the packagers don't like us rolling
LADSPA plugin code into our tree, tell them that this is the reason.
Like I said in my previous email, I haven't committed any changes to
the Mixxx code yet. All that's in trunk is the libs that will be
required when I do end up committing it. I still need to figure out
this broken button stuff.
Thanks,
Albert
