Question

我正在使用Ubuntu并尝试使用synaptic安装其中包含“GLUT”一词的所有内容以及SDL和opengl。但仍然是一个简单的程序无法编译。它显示了这个：

opengl1.cpp:(.text+0xe): undefined reference to `glClear'
opengl1.cpp:(.text+0x1a): undefined reference to `glBegin'
opengl1.cpp:(.text+0x2e): undefined reference to `glVertex2i'

opengl1.cpp:(.text+0xfd): undefined reference to `glLoadIdentity'
opengl1.cpp:(.text+0x12d): undefined reference to `gluOrtho2D'
/tmp/ccnwQeLu.o: In function `main':
opengl1.cpp:(.text+0x14a): undefined reference to `glutInit'
opengl1.cpp:(.text+0x156): undefined reference to `glutInitDisplayMode'
opengl1.cpp:(.text+0x16d): undefined reference to `glutInitWindowSize'
opengl1.cpp:(.text+0x181): undefined reference to `glutInitWindowPosition'
opengl1.cpp:(.text+0x18d): undefined reference to `glutCreateWindow'
opengl1.cpp:(.text+0x19e): undefined reference to `glutDisplayFunc'

/tmp/ccnwQeLu.o:(.eh_frame+0x12): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status

如果我使用g ++而不是gcc，我会得到这个：

vim opebgl1.cpp
g++ opengl1.cpp -o opengl1 -lGL -lstdc++ -lc -lm
 and then get this :
/tmp/ccCJBuIl.o: In function `MyInit()':
opengl1.cpp:(.text+0x12d): undefined reference to `gluOrtho2D'
/tmp/ccCJBuIl.o: In function `main':
opengl1.cpp:(.text+0x14a): undefined reference to `glutInit'
opengl1.cpp:(.text+0x156): undefined reference to `glutInitDisplayMode'
opengl1.cpp:(.text+0x16d): undefined reference to `glutInitWindowSize'
opengl1.cpp:(.text+0x181): undefined reference to `glutInitWindowPosition'
opengl1.cpp:(.text+0x18d): undefined reference to `glutCreateWindow'
opengl1.cpp:(.text+0x19e): undefined reference to `glutDisplayFunc'
opengl1.cpp:(.text+0x1a3): undefined reference to `glutMainLoop'
collect2: ld returned 1 exit status

那么我真的需要在Ubuntu中开始使用opengl吗？

Answer 1

将“-lstdc ++ -lGL”添加到链接器标志。或者尝试像这样编译它：

g++ opengl1.cpp -o opengl1 -lGL -lGLU -lc -lm

（编辑：添加-lGLU，删除-lstdc ++）

Answer 2

你应该将它与过剩和GLU联系起来：

g++ opengl1.cpp -o opengl1 -lGL -lstdc++ -lc -lm -lglut -lGLU

以 .cpp 结尾的文件必须使用 g ++ 进行编译。其余的错误与链接过程有关，如果使用我上面建议的命令构建应用程序，则不应该发生这些错误。如果有，请确保已安装 libglut 和 libglu 。

Answer 3

确保使用g++构建C ++文件，以避免与C ++标准库相关的链接器错误。

要解析GLUT符号，您可能只需要将-lglut添加到最终构建命令中。

Answer 4

编译代码时，必须根据包含内容提及一些参数。您已使用-lGL，-lm等。要使用gluOrtho2D，要使用的参数为-lGLU 以及以glut开头的其他功能使用-lglut
