linux - 编译OpenEXR时遇到 'undefined reference'和 'error adding symbols'

Question

这个问题已经有答案了:

What is an undefined reference/unresolved external symbol error and how do I fix it? (39 个回答)

已关闭 8 年前。

我正在安装OpenEXR_Viewers上Ubuntu 14.04 。运行 makefile 时，我遇到以下错误:

/usr/bin/ld: ImageView.o: undefined reference to symbol 'glOrtho' //usr/lib/x86_64-linux-gnu/mesa/libGL.so.1: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status

我的 lib 工具调用是否可能没有调用 GL？如果是这种情况，我该如何设置我的 libtool 以使用 GL 进行构建？ (编辑makefile以查看OpenGl)

尝试将 -lglut -lGL (可能还有 -lGLU)添加到链接器命令中。

( g++ linker: /usr/lib/libGL.so.1: could not read symbols: Invalid operation )

更新:

将其附加到:

FLTK_LDFLAGS = -Wl,-Bsymbolic-functions -lfltk_gl -lfltk -lX11
