Então, 15.04 x64, acabou de instalar.
Instalei o binário da nvidia da maneira antiga (console, desligando o lightdm) porque recebi um erro sobre a autenticação DRI2.
Então eu queria construir os exemplos nv opengl e eles dizem que estes eram o pré-requisito:
sudo apt-get install g++ binutils-gold xorg-dev libglu1-mesa-dev
Mas então ele reclamou da falta de libGL.so, então pesquisando no Google tentei instalar todas essas coisas:
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
e aí, não sei como, acabei com os drivers da nvidia desinstalados! (Havia também um autoremove no meio contendo algumas coisas do nv, talvez isso tenha bagunçado tudo)
De qualquer forma, depois de reinstalar novamente os binários nv, tento construir o vogl (uma ferramenta de depuração GL) e recebo novamente
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

O que há de errado, pessoal?

De qualquer forma, deixe-me resumir a história..
$ 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
e
lrwxrwxrwx 1 root root 15 mar 30 17:10 /usr/lib/x86_64-linux-gnu/mesa-egl/libEGL.so -> libEGL.so.1.0.0
Mas eu não tinha nenhum libEGL.so.1.0.0..
Parece que foi uma bagunça vindo dos binários mesa e nv
Instalei os binários pela terceira vez e funcionou.
Outra solução possível é a de Angelo Geels (nos comentários):
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
