You maybe just forgot to launch ldconfig. If you are trying to build things from git, right now Elementary (and a couple of other things) are in the process of being folded into the main EFL libraries, instead of being separate. On top of that, new EO infrastructure is also being added, but I think you have to explicitly enable beta APIs to get that new stuff. So that's currently all in a state of flux, may or may not work at any given moment, and the new stuff isn't well documented yet. Sticking with stable, released source tarballs of everything for the moment might be best. Especially for a newbie trying to figure out how to use it all. > Kind regards, > > 1) - path to libetrophy error > > When I try to run it, I got the following error message: > > elemines: error while loading shared libraries: libetrophy.so.0: > > cannot open shared object file: No such file or directory > > > > During the build, I figured out I needed etrophy, and built and > > installed the shared > > library for that.
