One simple question

whats are the library OpenGL 1.5 for download.

thanks all

excuse for the my english

there is no library to download to use it, if you mean this.
support for newer version/features of OpenGL comes to you by newer graphiccard drivers, from you manufacturer.

the things, that you might mean in your description, could be the header files - in OpenGL you have to use so called “bindingpoints” to use the latest features - and usually you have to write this bindinpoint-header file for yourself IF you don’t download it from another person, who has already written the file for you.

but there are no libraries to download.

i’m programmers for c++, and searched H files or sample cpp file for view use this
