我尝试运行与libGL一起使用的QTCreator，它崩溃并显示以下错误:

我运行glxgears，它可以工作(我看到车轮在移动)，并且显示了它使用的驱动程序:
t@t:/$ LIBGL_DEBUG=verbose glxgears -info

GL_RENDERER = AMD Radeon (TM) RX 460 Graphics

我试图建立一个符号链接(symbolic link)，以使QTCreator使用与glxgears相同的库:

那么，如何使用与glxgears相同的libGL库来使QTCreator成为可能？
最佳答案
删除符号链接(symbolic link)以避免出现分段问题，请尝试安装此链接:
apt-get intall -y mesa-utils and libgl1-mesa-glx
