I'm not sure if this is specific to rev. 6863, but it seems no matter what I do, 'Export Makefile' is disabled. Is there something I need to do to enable it?
You have to implement it :)
Search the forum for the cb2make tool or cbMakegen plugin
Fair enough. That being the case, shouldn't the option be removed from the menu as opposed to being disabled (at least until there is a plugin that actually provides that functionality)?
Probably, it is disabled since the 1.0rc days.
