Martin Stransky a65c7eb6a0 Bug 1409707 - [Wayland] - provide library shell, r=jhorak ... We don't add build-time dependency on Wayland libraries; that allows Wayland enabled Firefox builds to run on systems without Wayland support. We also can't dlsym() Wayland symbols directly from libwayland-client.so library as we miss global data entries referenced by code at wayland-client.h then. As a partial solution (for glibc systems only) we create dummy libwayland-client.so library implementation and place it *after* Gtk+ 3.0 libraries at linking time. It fixes build-time dependencies (we link against our libwayland-client.so library). Run-time dependency is resolved by ld.so - when Gtk+ 3.0 libraries are linked with system libwayland-client.so library, wayland symbols are pulled from there instead from our dummy libwayland-client.so library. When Gtk+ 3.0 is not linked with system libwayland-client.so it means we're running on system without Wayland support. Our dummy libwayland-client.so implementation is used (symbols are pulled run-time from there) and Firefox Wayland support is disabled then.
