On windows 10, this happen every time I link against libOpenGLAda.a. Output:

gprbuild -d -PC:\Users\ohenley\Desktop\OpenGLAda\examples\ogl_tutorials\02_red_triangle\tutorial_02.gpr -XMode=debug -XLibrary_Type=static -XAuto_Exceptions=enabled -XWindowing_System=windows -XGLFW_Version=3 Link [link] tutorial_02.adb C:\Users\ohenley\Desktop\OpenGLAda\lib\libOpenGLAda.a(gl-objects-programs.o):gl-objects-programs.adb:(.text+0x1369): undefined reference to `glEndTransformFeedback@0' collect2.exe: error: ld returned 1 exit status gprbuild: link of tutorial_02.adb failed [2018-04-08 14:36:31] process exited with status 4, 100% (91/91), elapsed time: 06.51s

I deleted the code concerning glEndTransformFeedback (End_Transform_Feedback) and it completes.

glBeginTransformFeedback and glEndTransformFeedback must be loaded with function pointers, but are not. I will fix this later today.
