因此,15.04 x64,刚刚安装。
我以旧方式(控制台,关闭 lightdm)安装了 nvidia 二进制文件,因为我收到有关 DRI2 身份验证的错误。
然后我想构建 nv opengl 样本,他们说这些是先决条件:
sudo apt-get install g++ binutils-gold xorg-dev libglu1-mesa-dev
但后来它抱怨缺少 libGL.so,所以我在谷歌上搜索并尝试安装所有这些东西:
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,我最终卸载了 nvidia 驱动程序!(中间还有一个包含一些 nv 内容的自动删除程序,也许把一切都搞乱了)
无论如何,在重新安装 nv 二进制文件后,我尝试构建 vogl(一个 GL 调试工具),然后再次
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

libEGL.so
libEGL.so.1
libEGL.so.346.59
各位,发生什么问题了?
答案1
无论如何,让我总结一下这个故事......
$ 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
和
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..
所以看起来这是来自 mesa 和 nv 二进制文件的混乱
我第三次安装了二进制文件并且成功了。
另一个可能的解决方案是 Angelo Geels 的解决方案(在评论中):
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
