编译 OpenEXR 时遇到“未定义的引用”和“添加符号时出错”[重复]

Question

我在Ubuntu 14.04 上安装OpenEXR_Viewers。运行makefile时遇到如下错误：

/usr/bin/ld: ImageView.o: 未定义对符号“glOrtho”的引用 //usr/lib/x86_64-linux-gnu/mesa/libGL.so.1：添加符号时出错：DSO 命令行 collect2 中缺失：错误：ld 返回 1 个退出状态

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

尝试将-lglut -lGL（可能还有-lGLU）添加到您的链接器命令中。

(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
