If you try to use the Makefile.examples in efl.git/src/examples/eolian_cxx to build, it errors because the eolian_cxx options aren't correct. Also it doesn't seem to build the right examples?
@felipealmeida I saw you pushed in a patch which mostly fixed this; I've done some further fixes here (in the branch) which add the eolian-cxx examples to the build.
This means only eina-cxx and efl-mono examples are missing functional makefiles here. I can leave this ticket open for that, or I can create a new one, whichever you prefer.
