yes Gtk.jl is not ready working on Julia master

[tknopp]

it seems an issue with

    macro assign_if_unassigned(expr)
        # BinDeps often fails and generates corrupt deps.jl files
        # (https://github.com/JuliaLang/BinDeps.jl/issues/146),
        # but most of the time, we don't care
        @assert expr.head === :(=)
        left = expr.args[1]
        right = expr.args[2]
        quote
            if !isdefined(current_module(), $(QuoteNode(left)))
                global const $(esc(left)) = $(esc(right))
            end
        end
    end

@vtjnash: Do you have an idea?

Looks like a julia bug. Minimal example:

macro m()
  :(global $(esc(:x)) = 1)
end

julia> @m
ERROR: syntax: malformed expression

Not sure if related, but this also happens:

julia> @macroexpand @m

@fcard: Great, could you please report this issue in at the Julia repo?

[tknopp]

(with a crosslink to this Gtk issue)

[fcard]

I made an issue already, and there is a fix on the way.

~I didn't mention this there but I was already planning to report back as soon as the PR was merged.~ I made the crossref.

[tknopp]

thanks!

[fcard]

This bug in particular is now fixed on master, but precompilation still doesn't work.

#331 has more stuff in it.
