我曾经update-alternatives选择NVIDIA-367作为opengl的提供者。
我运行了 ldconfig
我检查了所有符号链接是否有效并指向正确的文件夹·
root@laptop:/etc/ld.so.conf.d# ls -halt
lrwxrwxrwx 1 root root 41 sep. 2 18:59 i386-linux-gnu_EGL.conf -> /etc/alternatives/i386-linux-gnu_egl_conf
lrwxrwxrwx 1 root root 40 sep. 2 18:59 i386-linux-gnu_GL.conf -> /etc/alternatives/i386-linux-gnu_gl_conf
lrwxrwxrwx 1 root root 43 sep. 2 18:59 x86_64-linux-gnu_EGL.conf -> /etc/alternatives/x86_64-linux-gnu_egl_conf
lrwxrwxrwx 1 root root 42 sep. 2 18:59 x86_64-linux-gnu_GL.conf -> /etc/alternatives/x86_64-linux-gnu_gl_conf
root@laptop:/etc/alternatives# cat x86_64-linux-gnu_gl_conf
/usr/lib/nvidia-367
/usr/lib32/nvidia-367
但是当我-Wl,--verbose在构建项目期间传递给 g++ 时，仍然得到以下信息：

如您所见，没有任何地方提及 nvidia-367 文件夹，即使 ld config 明确配置为查看它。
是什么赋予了？
