after good people started to help me, the things started so get figured.
in order to have a working CDT, i've needed the foolowing
plugin-projects on my workspace:
and it lauched flawlessly.
later, i checkout'ed these projects from sources.redhat.com
the plugin is recognized but with some issues: this was the first one:
"The type org.eclipse.core.filesystem.IFileStore cannot be resolved. It
is indirectly referenced from required .class files"
class MakeGenerator.java, line 1056.
after some search, ive figured that IFileStore is inside eclipse and cdt
plugins uses it and don't have any issue.
the fixup was a modification in the MANIFEST.MF, adding a property found
inside another manifest, from org.eclipse.cdt.make.core. in the key
Require-Bundle, that property is needed:
but if it's added, 48 other errors inside automake will appear.
i think that's because some change in cdt, since the main difference now
is the previous error was about some not found class. this time are many
"must implement" errors.
i would like to get some advice, since i'm learning now about plugins,
and also don't know what to do if i make some change there.
