However this DLL does not provide an actual OpenGL implementation (apart from a software fallback which sole purpose is to act as a safety net for programs if no other OpenGL implementation is installed).
#OPENGL 32 BIT LIB 64 BIT#
The API binding library opengl32.dll (named so for both 32 bit and 64 bit versions of Windows) is shipped by default with every Windows version since Windows NT-4 and Windows 95B (both ca. So installing the OpenGL development files for Linux is usually taken care of with the installation of the desktop development meta package/s.* Microsoft Windows In most Linux distributions the development files for OpenGL are contained in a dedicated package, that is usually a dependency for a desktop application development meta-package. In Linux it is quite common to compartmentize the development packages for different aspects of the system, so that these can be updated individually. Hence modern OpenGL features are to be accessed through the extension mechanism, which is described in depth separately.
#OPENGL 32 BIT LIB INSTALL#
It is technically possible to program OpenGL on these operating systems without the requirement to install a dedicated SDK, assuming that a build environment following the targeted ABI is installed.Ī side effect of these strict ABI rules is, that the OpenGL version exposed through the binding interface is a lowest common denominator that programs running on the target platform may expect to be available. Such it is not necessary to actually install an SDK for OpenGL. the compiler and linker toolchain that natively targets these systems) must deliver also OpenGL API definitions. This has the notable effect, that system programming environments for these operating systems (i.e. Apple followed and in fact integrated OpenGL so deep into MacOS X, that the OpenGL version available is tightly coupled to the version of MacOS X installed. When OpenGL got first released the API somehow found its way into the ABI (Application Binary Interface) contract of Windows, Solaris and Linux (LSB-4 Desktop) in addition to it's origin Sun Irix. This might change in the future, when new GPU programming interface allow to truly implement OpenGL as a library, but for now it's a programming API towards the graphics drivers. And for the time being, OpenGL implementations are part of the GPU drivers. OpenGL by itself is merely a set of specifications on what commands an implementation must follow. This is not how OpenGL finds the way into computer system. This misconception leads to many questions in the form "how to I install OpenGL" or "where to download the OpenGL SDK". One of the most common misconceptions about OpenGL is, that it were a library that could be installed from 3rd party sources.
