我该如何修复此错误：找不到 -lglfw3 (Open Gl)

make我在执行命令时遇到此错误

/usr/bin/ld: cannot find -lglfw3
collect2: error: ld returned 1 exit status
CMakeFiles/wrapmodes.dir/build.make:95: recipe for target '../bin/wrapmodes' failed
make[2]:  [../bin/wrapmodes] Error 1
CMakeFiles/Makefile2:99: recipe for target 'CMakeFiles/wrapmodes.dir/all' failed
make[1]:  [CMakeFiles/wrapmodes.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make:  [all] Error 2

答案1

尝试将链接更改为glfw而不是glfw3。

当我尝试从 Windows 设置构建 Code::Blocks 项目时遇到同样的问题时，该解决方案对我有用。此外，我认为您还必须链接到GL而不是opengl或opengl32（不确定这是否适用于您）。

对于 openGL SuperBible，当我cmake从构建目录运行时：

cmake ..
CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

当我跑步时make：

make

[  5%] Built target sb7
Consolidate compiler generated dependencies of target alienrain
[  6%] Linking CXX executable /home/michael/Documents/OpenGL/SuperBible/sb7code-master/bin/alienrain

系统从 cmke dump 中找到了 glfw3，所以我必须找到在 make 序列中使用 -lglfw3 的位置，因此我进入/OpenGL/SuperBible/sb7code-master/build/CMakeFiles/wrapmodes.dir/，由于这是一个链接错误，我单击了 link.txt 并得到了类似这样的内容：

/usr/bin/c++  -fopenmp -D_LINUX -std=c++0x -rdynamic CMakeFiles/wrapmodes.dir/src/wrapmodes/wrapmodes.cpp.o -o /home/michael/Documents/OpenGL/SuperBible/sb7code-master/bin/wrapmodes   -L/home/michael/Documents/OpenGL/SuperBible/sb7code-master/lib  -Wl,-rpath,/home/michael/Documents/OpenGL/SuperBible/sb7code-master/lib lib/libsb7.a -lglfw3 -lX11 -lXrandr -lXinerama -lXi -lXxf86vm -lXcursor -lGL -lrt -ldl

我将所有文件夹和 link.txt 文件的 -lglfw3 替换为 -lglfw，然后运行make所有文件 make-d/built。

我必须将媒体文件复制到其中/bin/media。

当我进入 bin 文件夹并单击depthclamp时，我得到了一个正在运行的程序！我快速浏览了文件/二进制文件，并运行了几个带有着色器和纹理的程序，发现它们运行了。
