Crash at start on Win about glvisualize.jl HOT 18 CLOSED

That's weird. Can you try:

using GLFW, ModernGL
GLFW.Init()
GLFW.WindowHint(GLFW.CONTEXT_VERSION_MAJOR, 3)
GLFW.WindowHint(GLFW.CONTEXT_VERSION_MINOR, 3)
GLFW.WindowHint(GLFW.OPENGL_FORWARD_COMPAT, GL_TRUE)
GLFW.WindowHint(GLFW.OPENGL_PROFILE, GLFW.OPENGL_CORE_PROFILE)
window = GLFW.CreateWindow(10,10, "test")
GLFW.MakeContextCurrent(window)
println(bytestring(GLFW.GetVersionString()))
println(bytestring(glGetString(GL_VERSION)))
GLFW.ShowWindow(window)

from glvisualize.jl.

Ok, here it is

...
julia> window = GLFW.CreateWindow(10,10, "test")
GLFW.Window(Ptr{Void} @0x0000000000000000)

julia> println(bytestring(GLFW.GetVersionString()))
3.1.1 Win32 WGL MinGW DLL

julia> println(bytestring(glGetString(GL_VERSION)))
ERROR: ArgumentError: cannot convert NULL to string

julia> glGetString(GL_VERSION)

julia> GLFW.ShowWindow(window)

Please submit a bug report with steps to reproduce this fault, and any error messages that follow (in their entirety). Thanks.

using GLFW, ModernGL
GLFW.Init()
window = GLFW.CreateWindow(10,10, "test")
GLFW.MakeContextCurrent(window)
println(bytestring(GLFW.GetVersionString()))
println(bytestring(glGetString(GL_VERSION)))
GLFW.ShowWindow(window)

Does this work?

from glvisualize.jl.

No. Same problem. That NULL pointer seams the root of the problem

julia> window = GLFW.CreateWindow(10,10, "test")
GLFW.Window(Ptr{Void} @0x0000000000000000)

also, I noticed that you install both 32 & 64 bits versions MinGW and VS glfw3.dll but its the MinGW one that is finally used. I replaced it by the VS dll but it made no difference.

from glvisualize.jl.

yeah seems like it! You didn't forget GLFW.Init() by any chance? Would be really weird if it returns null in this scenario. Or are you in a virtual machine?

from glvisualize.jl.

Win 8.1, no virtual here

julia> using GLFW, ModernGL

julia> GLFW.Init()

julia> window = GLFW.CreateWindow(10,10, "test")
GLFW.Window(Ptr{Void} @0x0000000000000000)

from glvisualize.jl.

Do you have really old graphic driver? :D
The only other thing I can think of to get more information out of this, is to try if this works:

using GLFW, ModernGL
GLFW.Init()
GLFW.WindowHint(GLFW.OPENGL_PROFILE, GLFW_OPENGL_ANY_PROFILE)
window = GLFW.CreateWindow(10,10, "test")
GLFW.MakeContextCurrent(window)
println(bytestring(GLFW.GetVersionString()))
println(bytestring(glGetString(GL_VERSION)))

from glvisualize.jl.

Something is showing up. The hardware is a 2014 MBP running Windows through Bootcamp, so graphic specs should be pretty 'decent'

julia> using GLFW, ModernGL

julia> GLFW.Init()

julia> GLFW.WindowHint(GLFW.OPENGL_PROFILE, GLFW_OPENGL_ANY_PROFILE)
ERROR: UndefVarError: GLFW_OPENGL_ANY_PROFILE not defined

julia> window = GLFW.CreateWindow(10,10, "test")

Ugh, sorry, GLFW.OPENGL_ANY_PROFILE

from glvisualize.jl.

This?

from glvisualize.jl.

Yeaah...
Sorry for poking around in the dark here.
Okay, last combination I can think of:

using ModernGL, GLFW
GLFW.Init()
GLFW.WindowHint(GLFW.CONTEXT_VERSION_MAJOR, 3)
GLFW.WindowHint(GLFW.CONTEXT_VERSION_MINOR, 2)
GLFW.WindowHint(GLFW.OPENGL_PROFILE, GLFW.OPENGL_CORE_PROFILE)
GLFW.WindowHint(GLFW.OPENGL_FORWARD_COMPAT, GL_TRUE)
window = GLFW.CreateWindow(10,10, "test")

If this doesn't work, you should make sure that you have the latest drivers installed... If you already have them, I'd be a little clueless. Since GLFW.Init() doesn't error, GLFW should be intact.

from glvisualize.jl.

Sorry, still no difference. I'll try to see about updating those drivers latter (not sure where to look yet). Have to go now.
Thanks for your attempts.

from glvisualize.jl.

Thanks for your patience :)

from glvisualize.jl.

Simon, it works after updating my Nvidia drivers. Strange but that's how it is.

One last thing. What is the best channel if I want to bug you with help questions?

from glvisualize.jl.

It's not that strange, just sad that they don't update more regularly and automaticaly.
I do answer emails, but feature requests, bug reports and needs for more documentation work best via issues, so others can find it as well and I can better keep track of the status.

from glvisualize.jl.

OK, thanks. I do have this WIP package https://github.com/joa-quim/GMT.jl that allows me to load or generate lots terrain models (for example) and would like to see how easy would be to display them with GLVisualize. I was already able to see something but it also raised me lots of questions on how to to it better.

from glvisualize.jl.

Sounds cool :)
Yeah just open an issue, make pictures of the current state and your target and I can see what we can do! And best would be, if you supply me with working example code, so that I can play around with it.

from glvisualize.jl.

OK, I'll prepare an example case with code and some questions but have not much time right now.
