0.5.0-rc2 qt linking error

[rapus95]

coming from there: JuliaPy/PyPlot.jl#237
that's the error now:

julia> using Conda

Try opening the Windows command line and running C:\Users\necka\.julia\v0.5\Conda\deps\usr\ Scripts\conda install -y pyqt to see if the error recurs. If so, then the problem may be with with Anaconda itself, not Conda.

It sounds similar to ContinuumIO/anaconda-issues#555 or especially https://github.com/conda/conda#1811 ... see the comments in those issues for suggestions.

(Note: I found those issues by googling "post-link failed" qt. Googling keywords from the error message is always a good first thing to try when you encounter a problem.)

[rapus95]

running the command you recommended indeed WORKED and solved my problem. So when it was executed from within julia it didn't work, but running it from cmd directly it worked... That's strange.
Thanks for solving.

Close the problem because there is a solution or keep it open because you need to workaround?

[stevengj]

I guess keep it open? The problem with this sort of thing is reproducing it.

Could this be the same issue that #41 is trying to solve (i.e. a linking error of Qt on Windows?)

[stevengj]

@Luthaf, that sounds like a possibility.

[Luthaf]

It looks like this have been resolved with 0.5-rc3. @rapus95, could you try to check if this works for you?

[stevengj]

Seems resolved?
