Skinning solutions and body animation

Then the question is where to continue, from your build (using dglOpenGL) or mine (using the built-in OpenGL). Yours crashes, mine runs but shows nothing. Not very easy to work from there I'm afraid.

Using Mac OS X Lion and FreePascal 2.7.1 I get this error while compiling and linking one of the examples:

Assertion failed: (_dependentDylibs.size() != 0), function File, file /SourceCache/ld64/ld64-123.2.1/src/ld/parsers/macho_dylib_file.cpp, line 391.

I used dglOpenGL to build the library, but integrated those changes in dglOpenGL to get it working properly on Mac OS X.

I'm pretty sure I was able to compile it on Mac OS Snow Leopard, but it crashed when I tried to execute one of the examples.

I just got curious: Is dglOpenGL better than the built-in OpenGL interfaces in some way? I want to use the best headers, obviously.

I just got curious: Is dglOpenGL better than the built-in OpenGL interfaces in some way? I want to use the best headers, obviously.

The difference I've heard of is that dglOpenGL supports OpenGL 3 and higher while the FreePascal standard GL header doesn't. But that may just be misinformation on my part, because I've heard since that the FPC GL header supports up to OpenGL 4 as well. I've never tried it though.
On Mac OS X, it doesn't really make a difference, as Apple only has a complete implementation of OpenGL 2.1 in their drivers and everything newer is just partially supported. dglOpenGL has pretty fast updates, once a new specification has been releaved. (But they still don't officially support Mac OS X and each time they release a new header, you have to apply the patch I posted and in a few cases they patch didn't work and dglOpenGL was unusable on the Mac.)

I think the major bonus is that you can use dglOpenGL header with both Lazarus and Delphi. It might be incredibly difficult to transfer fpc header to Delphi, and Delphi has its propably outdated header of its own.
