hi. ok, first of all I thought I'd point this out to anyone on linux who wants to use glee.d GLX functions.

#1) glee.d has no glx functions

#2) right now i don't have the will power to shift through all the GLX functions, (maybe in the future if i ever really need them). However, if there's someone that does need them, then take a look at http://www.dsource.org/svn/projects/claytek/claytek/src/derelict/opengl/glee.d
at the moment I have the glGetErrorStrGLX function added and all the GLX C stuff is commented out in a version (linux) block at the end of the file. search "glx"

#3) a) glee.d is perfectly happy importing gltypes.d instead of glConstants.d . hence there's not much need for glConstants.d. I believe they accomplish the same thing?
b) I think glee.d and glu.d should be put in the opengl/ directory, along with any future opengl stuff

Also, I have a simple question. Why is it that (at least in c++, in D too?) you must define GLee.h before all other GL files?

Initially glee.d in Derelict did both a and b. I was importing gltypes.d directly and it was in the opengl directory. But the D glee I am using is not mine, and is not part of Derelict. In order to ensure that Derelict's GLee did not deviate from Joel Anderson's original D port, the current setup was introduced at his request. Now, if Joel updates the original and I don't get around to dropping it into svn for Derelict, you can just plug it in to your existing Derelict package without any modifications (on Windows anyway).

Now, I'm thinking it might be a good idea to drop GLee from Derelict entirely. If anyone wants to use it they will be able to. It is only provided as a convenience anyway, to avoid conflicts between glConstants.d and gltypes.d. The more I think about it, the more I'm sure dropping it is the right thing.

Take a look at GLee.h and find out Smile I'm not sure off the top of my head.

okay. i know glee in derelict is now dead but i'm trying to use glee anyways and i get the following errors.

Code:

libGLee.so: undefined reference to `glXGetCurrentDisplay'
libGLee.so: undefined reference to `glXQueryExtensionsString'
libGLee.so: undefined reference to `glXGetProcAddressARB'


is there an easy way to add these definitions to glee.d ?

is it better to not use glee.d and load extensions manually? how would i go about doing this?

thanks.

In order to get these into GLee, you'll also have to modify the C code Joel added to the D port some time back. It might be better just to load them manually. I'd opt for loading them manually. DerelictGL needs to be loading glXGetProcAddress as part of the Linux port, and through that you can load the extensions you need. And I'm not sure, but I think glXGetCurrentDisplay and glXQueryExtensionsString are part of the core library on Linux as well, and not extensions.

The DerelictGL linux port is on my todo list for this weekend. If I can, I'll get to it sooner.
