parts of OpenTK are include inside Xamarin.Mac.dll
cause of that we can't link with a newer OpenTK, that supports OpenGL 4, etc..
and we are stuck with the old open TK shipped with xamarin.
also can'f find where is located OpenTK.Graphics.GraphicsContext in xamarin.mac.dll
and without GraphicsContext it's impossible to make multithreaded OpenGL renderer
it's worst than that, just a small part of OpenTK is include, and impeach to link with OpenTK..
I found the problem, xamarin.mac mobile include opentk, but opentk is missing in xamarin.mac 4.5 (supported version)
kist the openTk maths are include that impeach to link with our own openTK
using xamarin.mac mobile, it's possible to reference the provided OpenTK, but it can't be used cause of the missing System.drawing, and that we can't reference other libraries.
using xamarin.mac 4.5 (supported) , system.drawing is available, parts of OpenTK are include directly in xamarin.mac, but the real OpenTK isn't provided, and it's not possible to link with a third party OpenTK cause of included parts (vector, matrix, etc..)
I need to use xamarin mac with my own OpenTK
and not your broken old one
I don't understand, if you want to build an unified API, why you didn't kept the same OpenTK for xamarin.mac than on linux, monomac, ios and android..
it was the only graphics part that was unified already... :/
please stop making new broken things and fix old ones, xamarin is always unusable for real projects cause of untested modifications... and ship the missing OpenTK library for net 4.5.. and please remove the parts of OpenTK included in Xamarin.Mac.
Ok, GraphicsContext isn't necessary with the xamarin.mac mobile framework OpenTK, as it works without the needs of dummy openTK context..
finally, the only problem I found was the missing missing OpenTK library in net45. and a problem with GL.DeleteProgram (I filled a new bug report)
if OpenTK working, I don't care so much to not using my own OpenTK...
I'm having trouble following your bug, but it sounds like it is resolved. Please open a new bug and clearly describe the problem (preferably with an example showing the issue) if it still exists.
