things that need verified as either cl-opengl bugs, or problems with new enough groups in gl.xml:

:FRAMEBUFFER-EXT is not defined as a keyword for enum type #<CFFI::FOREIGN-ENUM CL-OPENGL-BINDINGS::FRAMEBUFFER-TARGET>.

• (%GL:BIND-FRAMEBUFFER-EXT :FRAMEBUFFER-EXT 1)
• (%GL:FRAMEBUFFER-TEXTURE-2D-EXT :FRAMEBUFFER-EXT :COLOR-ATTACHMENT0-EXT :TEXTURE-2D 1 0)
• (gl:framebuffer-renderbuffer-ext :framebuffer-ext :depth-attachment-ext :renderbuffer-ext depthbuffer))

:RENDERBUFFER-EXT is not defined as a keyword for enum type #<CFFI::FOREIGN-ENUM CL-OPENGL-BINDINGS::RENDERBUFFER-TARGET>.

• (CL-OPENGL-BINDINGS:BIND-RENDERBUFFER-EXT :RENDERBUFFER-EXT 1)

`:MAX-TEXTURE-MAX-ANISOTROPY-EXT is not defined as a keyword for enum type #.)

• (CL-OPENGL:GET-FLOAT :MAX-TEXTURE-MAX-ANISOTROPY-EXT 1)

[3b]

:UNSIGNED-INT-24-8 is not defined as a keyword for enum type # calling glTexImage2D also check :float-32-unsigned-int-24-8-rev and others in that group

[3b]

from #93: in glTextureSubImage3d

:UNSIGNED-INT-8-8-8-8-REV is not defined as a keyword for enum type #<CFFI::FOREIGN-ENUM CL-OPENGL-BINDINGS::PIXEL-TYPE>.

:UNSIGNED-INT-2-10-10-10-REV is not defined as a keyword for enum type #<CFFI::FOREIGN-ENUM CL-OPENGL-BINDINGS::PIXEL-TYPE>.

also check :unsigned-int-5-9-9-9-rev

Adding error details as requested in #lispgames (hoping I understood the request correctly): When building nineveh (using SBCL 2.0.9 and 2.0.9.48, as well as CCL v1.12-32):

Noticed this comment: {TODO} make a PR to add this to cl-opengl close to the macro definition.

Possible solution

Replacing mapbufferusagemask with mapbufferaccessmask in CEPL seems to be all that's needed to solve the nineveh issue.

[3b]

Gave up on the new enum groups in order to get cl-opengl development moving again, so closing this.

(Didn't have enough energy to get the gl spec changes upstream, and the more specific enum types seemed to cause more problems than they helped anyway)
