我正在尝试构建 Cube2 Sauerbraten，但我需要 OpenGL 和 SDL2 库来运行 makefile。（我在这里使用 ubuntu）我尝试运行sudo apt-get install --yes software-properties-common g++ make然后sudo apt-get install --yes libsdl2-dev最后sudo apt-get install --yes freeglut3-dev，编译，g++ main.cpp -I /usr/include/SDL2/ -lSDL2 -lGL.

我从https://gist.github.com/dirkk0/cad259e6a3965abb4178获得了这些命令。当我运行它们时，前三个命令工作正常，但最后一个没有工作，给了我这个错误。

optiplex780@super-OptiPlex-780:~$ g++ main.cpp -I /usr/include/SDL2/ -lSDL2  -lGL
cc1plus: fatal error: main.cpp: No such file or directory
compilation terminated.
optiplex780@super-OptiPlex-780:~$

我应该用makefile替换main.cpp吗？

我只是个笨蛋，还是这里有问题？安装软件包后，我尝试进入~/sauerbraten/src目录并运行make install. 我得到了这些错误。

我正在研究 OpenGL 着色器，我需要 uint64_t 类型等...但是，当我执行 glxinfo 时，此扩展不在列表中。

我正在使用 Mesa 18.0.5，并且此页面告诉 17.1.0 的 radeonsi 驱动程序支持该扩展。

我的 GPU 是 AMD Radeon HD 8730M。我正在使用radeon驱动程序，但切换到amdgpu没有帮助。

问题：如何在我的着色器中使用 uint64？通过切换到另一个驱动程序？通过更新 Mesa？还是我的 GPU 太旧了？

我尝试编译的着色器：

#version 450
#extension GL_ARB_gpu_shader5 : enable
#extension GL_ARB_gpu_shader_int64 : enable

void main()
{
  uint64_t foo = 0ul;
}

我有：

0:3(12): warning: extension `GL_ARB_gpu_shader_int64' unsupported in fragment shader
0:7(11): error: syntax error, unexpected NEW_IDENTIFIER, expecting ',' or ';'

glxinfo 输出：

name of display: :0.0
display: :0  screen: 0

我在笔记本电脑上运行 Linux Mint 19.1 并面临这个问题。当我尝试使用 OpenGL 库编译 C++ 程序时，它说：

$ make
g++     solsys.cpp  -lglut -lGLEW -lGL -lGLU -fpermissive -o solsys
/usr/bin/ld: cannot find -lGL
collect2: error: ld returned 1 exit status
<builtin>: recipe for target 'solsys' failed
make: *** [solsys] Error 1

当我之前尝试运行已经编译的程序时，但在这台机器上它说

./rotation: error while loading shared libraries: libGLEW.so.1.13: cannot open shared object file: No such file or directory

我实际上理解问题在于库安装不正确，但无法解决。

glxino | grep OpenGL输出这个

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile 
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.0.5
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 18.0.5
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 18.0.5
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10
OpenGL ES profile extensions:

顺便说一句，我在笔记本电脑上安装 Nvidia 驱动程序时遇到了问题，但后来放弃了。

$lspci | grep "NVIDIA"
