c++ - OpenGL 3.2: Cache compiled shaders?

Question

Is there any way to cache compiled shader programs using OpenGL 3.2?

I've looked at ARB_get_program_binary but found my driver does not support it.

I'd like to be as compatible with older cards as possible so switching to OpenGL 4 is not a good solution.

I'm working with Qt5.1 and using QOpenGLFunctions_3_2_Core to access OpenGL functions.

此外ARB_get_program_binary，没有 OpenGL 功能来查询/缓存已编译的程序对象。

请注意，某些驱动程序自己会缓存程序二进制文件，例如 NVidia 的专有 Linux 驱动程序，它使用~/.nv/GLCache目录来存储缓存的对象。我不确定其他驱动程序是否也有这样的缓存，但我觉得很有可能。
