Error on example

[jtravs]

I get the following error

ERROR: LoadError: LoadError: InitError: No ApplicationManager instance created
 in __init__() at C:\Users\John\.julia\v0.5\QML\src\QML.jl:32

when trying to run the repl_background example. Any tips?

If you checked out QML, be sure to also checkout CxxWrap and do

Pkg.build("QML")

after that. Also, this example is meant to be included from the repl using include(path-to-jl-file), you did that, right?

[jtravs]

Yes, I did that:

WARNING: QML had build errors.

Ah, sorry, on Windows it will download a binary by default, and that is not updated with the changes to the code. The repl example should work in the latest released version also (i.e. by Pkg.free on both QML and CxxWrap), or otherwise the easiest way to build binaries on Windows yourself is as follows:

• Install visual studio 2015 community edition
• Install cmake and make sure it is in the path
• Install Qt using the official installers
  Next, in Julia set:

ENV["QT_ROOT"] = "C:\Qt\5.7" # or where Qt is installed
ENV["BUILD_ON_WINDOWS"] = 1

And then build the QML package again. Note that this needs a lot of disk space: VS takes about 10 GB and Qt about 5 GB if I remember correctly. Hopefully it will turn out to be possible to release binaries automatically with appveyor, that should eliminate this problem.

Perhaps this can be closed now that 0.8 is released?
