所以，我最近收到一位客户的投诉，抱怨我们的软件在他的 ubuntu 16.04 PC 上崩溃了。他说该软件最初可以正常工作，但一段时间后当他尝试使用它时，软件崩溃了。
他最初的运行给出了以下错误/警告：
libGL error: unable to load driver: nouveau_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: nouveau
libGL error: unable to load driver: nouveau_dri.so
libGL error: driver pointer missing

我关注了@的答案在 ubuntu 15.04 上安装 Steam 时出错 来定位问题，但是失败了。
我曾要求他向我发送 LIBGL_DEBUG 的输出，其输出为：

如您所见，该项目使用 Qt 和 OpenGL。我真的不知道问题可能是什么。任何建议都将不胜感激。
PS 我注意到他的库在 lib/ 文件夹中（尽管他使用的是 x86_64 库），而我们的库在 lib64/ 中（其中代码运行良好）。
