Using GLPlot.jl: Inexact Error (Julia v0.4.0-dev OSX 10.9.5)

[maxruby]

When trying to simply load GLPlot with using, I get the following error:

julia> using GLPlot
ERROR: InexactError()
 in include at ./boot.jl:242
 in include_from_node1 at ./loading.jl:128
 in include at ./boot.jl:242
 in include_from_node1 at ./loading.jl:128

. . . very long ERROR message (see Full ERROR ). It seems that this stems from the many calls e.g., convert(GLenum, 0x0DD1) in glConstants.jl.

Any thoughts on what I should do to get through?

I should really tag new versions... You need to checkout master: Pkg.checkout("GLPlot"); Pkg.checkout("GLWindow"); Pkg.checkout("GLAbstraction"); Pkg.checkout("ModernGL")

Cheers and sorry for the inconvenience, Simon On 10 Dec 2014 01:41, "Maximiliano Suster" notifications@github.com wrote:

Thanks. Now, when I try the simple demo Image viewing, I get a lot of warnings and a fatal ERROR: stack overflow. In addition, the window seems to be stuck and I am unable to close it manually. The entire process took several seconds to complete, is this normal?

That must be still old code...Did you do Pkg.update() recently? WARNING: apply(f, x) is deprecated, usef(x...)instead Should be fixed in the newest tagged version of Reactive. This is how the image example in master should look like: https://github.com/SimonDanisch/GLPlot.jl/blob/master/example/image.jl So I assume that you're still not on master with GLPlot...

[maxruby]

I did Pkg.checkout exactly as you told me. Now I will do Pkg.update(). . .

[maxruby]

Uhmm, this is going to be fun. The Pkg.update() broke my Cairo installation with a new ERROR - that is exactly why I hesitate to update too often while developing my own package. . .
Meanwhile, I still get the ERROR from Reactive.jl so I guess I need to build it again separately?
I did both Pkg.checkout and Pkg.update as you said - still I get the warnings and messages and its all slow.

[SimonDanisch]

How painful... :( Didn't expect that to be an issue. Could Reactive be dirty and that's why it didn't update? You can also just checkout Reactive as well ;) And if this all doesn't work, you can always just go into the folders and do git pull origin master and if this fails due to the package being dirty, just do a git reset --hard HEAD. Or just delete all the folders and install it with checkout ;)

[maxruby]

OK. Now it worked after Pkg.build("Reactive") and then restarting Julia once more. The WARNING: apply(f, x) is deprecated, usef(x...)instead is still there though and the entire process to plot the image takes over 10s?

[SimonDanisch]

Well then just do a Pkg.checkout("Reactive"). The package is admittedly very slow to load, but plotting itself should be very fast ;)

[maxruby]

OK. Now it works as I would have expected - as you said, it is just the package loading time that is quite long. . . However, I am aware that this is a challenge for all packages. I will close the issue then?

[SimonDanisch]

Was there a single issue that I could fix, to make this less painful? In other words, will tagging GLPlot, GLAbstraction, ModernGL, GLWindow make the installation run smooth?

[maxruby]

I think you should definitely tag those, and at least indicate the changes necessary to get it to work smoothly with v0.4.0-dev. Currently, you definitely need the following for it to work:

Pkg.checkout("GLPlot");
Pkg.checkout("GLWindow");
Pkg.checkout("GLAbstraction");
Pkg.checkout("ModernGL");
Pkg.checkout("Reactive");

A polite reminder to do Pkg.update() after that is worthwhile too.

Okay thanks!
