Question

导入的目标"Qt5::Gui"引用了文件"/usr/lib/x86_64-linux-gnu/libEGL.so"，但该文件不存在。

所以，15.04 x64，刚刚安装好。

我按照以前的方式安装了Nvidia二进制文件（通过控制台，关闭lightdm），因为我遇到了DRI2身份验证错误。

然后我想要构建nv OpenGL示例，他们说这些是先决条件：

sudo apt-get install g++ binutils-gold xorg-dev libglu1-mesa-dev

但是它抱怨缺少libGL.so，所以我在网上搜索后尝试安装了所有这些东西：

   61  sudo apt-get install libgl1-mesa-dev 
   62  sudo apt-get autoremove
   63  make
   64  sudo apt-get install mesa-common-dev 
   65  sudo apt-get install freeglut3-dev freeglut3
   66  make
   67  sudo apt-get install build-essential

然后，我不知道怎么回事，最终卸载了NVIDIA驱动程序！（中间还有一个自动删除的过程，其中包含一些nv的东西，可能把一切都搞砸了）

无论如何，在重新安装了nv二进制文件之后，我尝试构建vogl（一个GL调试工具），结果又出现了同样的问题。

elect@elect-desktop:~/NetBeansProjects/vogl/vogl_build/release64$ cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_X64=On ../..

cmake options:
  -DCMAKE_BUILD_TYPE='Release': Build debug or release. (Debug|Release)
  -DVOGLTEST_LOAD_LIBVOGLTRACE='': glitest will load libvogltrace.so manually (don't implictly link against libgl.so). (On|Off)
  -DVOGLTRACE_NO_PUBLIC_EXPORTS='OFF': Don't define any public GL exports in libvogltrace.so. (On|Off)
  -DVOGL_ENABLE_ASSERTS='OFF': Enable assertions in all voglcore builds (including release). (On|Off)
  -DCMAKE_VERBOSE='OFF': Spew cmake project options. (On|Off)
  -DBUILD_X64='On': Build 32 or 64-bit. (On|Off)
  -DWITH_ASAN='OFF': Build with Address sanitizer. (On|Off)
  -DUSE_TELEMETRY='OFF': Build with Telemetry. (On|Off)
  -DUSE_MALLOC='': Use system malloc (not STB Malloc). (On|Off)

Not forcing assertions to be enabled (VOGL_ENABLE_ASSERTS=FALSE)
libvogltrace.so will define GL/GLX public exports

怎么了，伙计们？

总之，让我来概括一下故事...

$ ls /usr/lib/x86_64-linux-gnu | grep -i libegl
libEGL.so 
libEGL.so.1 
libEGL.so.346.59

ls -l /usr/lib/x86_64-linux-gnu/libEGL.so
lrwxrwxrwx 1 root root 18 mar 30 17:10 /usr/lib/x86_64-linux-gnu/libEGL.so -> mesa-egl/libEGL.so

并且

lrwxrwxrwx 1 root root 15 mar 30 17:10 /usr/lib/x86_64-linux-gnu/mesa-egl/libEGL.so -> libEGL.so.1.0.0

但是我没有任何libEGL.so.1.0.0的文件。

看起来这可能是由于mesa和nv二进制文件引起的混乱。

我第三次安装了这些二进制文件，然后它就正常工作了。

另一个可能的解决方案是Angelo Geels在评论中提到的方法。

sudo rm /usr/lib/x86_64-linux-gnu/libEGL.so; sudo ln /usr/lib/x86_64-linux-gnu/libEGL.so.1 /usr/lib/x86_64-linux-gnu/libEGL.so
