So you would make the *target* EFL package depend on lua 5.1, so that
the *host* EFL package also gets built against the host Lua 5.1 ?

I guess there is no way of disabling Lua support ? :-)

So, yes, in the mean time, please add the dependency, and report the
problem upstream. BTW, did you test the  --enable-lua-old option that
is mentioned in
https://git.enlightenment.org/core/efl.git/commit/?id=6124d0733657e425001ce51f526aea3bb8dc54e7,
which you pointed ?

I don't understand. Isn't the SED precisely here to prevent the
documentation from being built ?

What was the feedback ?

I think we should try to use the mainline gdb. We have a Microblaze
Qemu configuration, so we can at least do some basic testing here.

Can you submit a patch ?

Ok, good.

Thanks. The only thing that bothers me a bit is that we will likely
forget to remove all those "depends on BR2_nios2". But I guess we don't
really have the choice.

Thanks,
