Test failure: getgc has no method matching getgc(::Canvas)

[wkearn]

Just started getting this error today.

julia> Pkg.test("Winston")

I got the same error on a couple different versions of Julia:

0.3

I tried it again on an 0.4 commit (a couple of days off of master) and got the same error.

Thought it might be something weird going on with my desktop, so I tried in on my Macbook Air and got the same error:

I suspect this will be fixed by #202, but I haven't had time to test yet.

I am having similar error

[wkearn]

Confirmed that this is fixed by #202

Thanks, @timholy for pointing that out.

[timholy]

Thanks for testing.

[weijianzhg]

Yes, #202 fixed my problem as well. Thanks!

[rickedanielson]

Just to summarize the above (a nice exercise until the fix gets "in"):
Pkg.status()
Pkg.test("Winston") gives the getgc error (fix is "out")
Pkg.checkout("Winston") puts Winston on the master (fix is in)
Pkg.status()
Pkg.test("Winston") passes tests
Pkg.free("Winston") (fix is back out)
Pkg.test("Winston") gives the getgc error again

[wkearn]

This error has reappeared on 0.3 for me.

It's related to JuliaGraphics/Graphics.jl#1

The temporary fix in that issue (Pkg.checkout("Graphics","jcb/exportbase")) seems to solve it.
