C语言 Mesa glGetString()版本不同于glxinfo

Question

在我的应用程序中，我有这段代码

void showOpenGLInfo()
{
printf("Graphic card vendor: %sn", glGetString(GL_VENDOR));
printf("Renderer: %sn", glGetString(GL_RENDERER));
printf("GL version: %sn", glGetString(GL_VERSION));
printf("GLSL version: %sn", glGetString(GL_SHADING_LANGUAGE_VERSION));
}

在应用程序日志中显示此输出:

Graphic card vendor: Intel
Renderer: Mesa Intel(R) UHD Graphics 600 (GLK 2)
GL version: 4.6 (Compatibility Profile) Mesa 20.3.5
GLSL version: 4.60

我已经从源代码构建了Mesa驱动程序22.0.1版本，并且glxinfo报告了正确的值:

OpenGL version string: 4.6 (Compatibility Profile) Mesa 22.0.1

我不明白这个区别，有什么建议吗?Debian 11 Bullseye.

添加一些OpenGL信息:

OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) UHD Graphics 600 (GLK 2)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 22.0.1
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6 (Compatibility Profile) Mesa 22.0.1
OpenGL shading language version string: 4.60
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 22.0.1
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

根据注释添加其他信息:

Answer 1

我发现了错误。我的应用程序指向/lib/x86-64-linux-gnu而不是/lib/x86_64-linux-gnu。现在我可以使用Mesa 22.01从源代码构建。非常感谢@genpfault和@derhass的帮助
