libGL.2 libGL.s1

In the library directory, you will see various versions. For example:

•libGL.1 is a 10.20 compatible library for applications which were built on 10.20.

•libGL.2 is the library which is for applications built on 11.x (this is why libGL.sl is a symbolic link to libGL.2).

There is only one set of libraries in 11.x for 64-bit. These libraries are version number 2.

The other libraries you will see in these directories are all drivers for specific graphics devices. Device drivers, which have names of the form libdd* are loaded automatically at execution time, contingent upon device type. The user program does not specifically link in a device driver.

supported graphics devices

These are the graphics devices that support OpenGL:

•HP Visualize fxe

•HP Visualize fx-5

•HP Visualize fx-10

•HP Fire GL-UX

•ATI FireGL X1

•ATI FireGL T2

•ATI FireGL X3

supported operating systems

OpenGL is supported on PA-RISC 2.0 systems running the 64-bit version of HP-UX 11.0 and 11i v1 (11.11).
