Gtk.jl not working on Ubuntu 12.04, 64 bits

[Uwe Fechner]

Hello,

I installed Gtk.jl as described at https://github.com/JuliaLang/Gtk.jl .

Nevertheless, using Gtk fails:

julia> using Gtk

Any idea how to fix this?

Are your packages up-to-date?

Also, the README should be updated; these days, just Pkg.add("Gtk") should be
sufficient.

I updated all Ubuntu packages, deleted the .julia folder and reinstalled Gtk, using
Pkg.add("Gtk").

Still the same problem.

Any idea?

The error message is on glib. Check, where it resides and what version number it has. Then see, if deps,jl is matching.

[Uwe Fechner]

I found:
ufechner@uwe-desktop64:/lib/x86_64-linux-gnu$ ls libgl*
libglib-2.0.so.0  libglib-2.0.so.0.3200.4

The file ~/.julia/v0.3/Gtk/deps/ext_glib.jl contains:
if isfile(_depspath)
    include(_depspath)
else
    if OS_NAME == :Windows
        const libgobject = "libgobject-2.0-0"
        const libglib = "libglib-2.0-0"
    else
        const libgobject = "libgobject-2.0"
        const libglib = "libglib-2.0"
    end
end

For me, this looks correct. Any idea?

Is BinDeps generating a corrupt `deps.jl` file? Try deleting that and seeing if it works.

The output of BinDeps.debug("Gtk") will be helpful. You will have to "using BinDeps" first, of course.

Output of BinDeps.debug("Gtk"):

Any ideas?

Ok, this helped. I renamed the file deps.jl and now everything works fine.

Content of the deps.jl file:
macro checked_lib(libname, path)
        (dlopen_e(path) == C_NULL) && error("Unable to load \n\n$libname ($path)\n\nPlease re-run Pkg.build(package), and restart Julia.")
        quote const $(esc(libname)) = $path end
    end
Any idea were this wrong file is coming from and how to fix the error in the package?

@Keno. Can you investigate why BinDeps is sometimes generating corrupt deps.jl files?
