Mac - OpenGL - 未找到 glew

Question

基本上我试图弄清楚为什么编译器抱怨缺少 glew-library：

fatal error: 'GL/glew.h' file not found

我的设置：

酿造清单：

glew
glfw
glm

在 /usr/local/include 目录中：

GL -> ../Cellar/glew/2.0.0/include/GL
GLFW -> ../Cellar/glfw/3.2.1/include/GLFW
glm -> ../Cellar/glm/0.9.8.3/include/glm

和生成文件：

# OBJS specifies which files to compile as part of the project
OBJS = *.cpp

# CC specifies which compiler we're using
CC = g++

# INCLUDE_PATHS specifies the additional include paths we'll need
INCLUDE_PATHS = -I/usr/local/include -I/opt/X11/include

# LIBRARY_PATHS specifies the additional library paths we'll need
LIBRARY_PATHS = -L/usr/local/lib -I/opt/X11/lib

# COMPILER_FLAGS specifies the additional compilation options we're using
# -w suppresses all warnings
COMPILER_FLAGS = -w

# LINKER_FLAGS specifies the libraries we're linking against
# Cocoa, IOKit, and CoreVideo are needed for static GLFW3.
LINKER_FLAGS = -framework OpenGL -lglfw3 -lglew

# OBJ_NAME specifies the name of our exectuable
OBJ_NAME = main

#This is the target that compiles our executable
all : $(OBJS)
    $(CC) $(OBJS) $(INCLUDE_PATHS) $(LIBRARY_PATHS) $(COMPILER_FLAGS) $(LINKER_FLAGS) -o $(OBJ_NAME)

当我在同一目录中有一个名为 File.cpp 的文件时，我运行：

make File

我得到：

fatal error: 'GL/glew.h' file not found

谁能解释为什么上述设置是错误/损坏的？

您应该确保您的目录结构正确。

例如，您描述了包含的目录结构，如下所示：

GL -> ../Cellar/glew/2.0.0/include/GL
GLFW -> ../Cellar/glfw/3.2.1/include/GLFW
glm -> ../Cellar/glm/0.9.8.3/include/glm

这有点像库的默认目录结构，因为它们从您下载的存档中解压时存在，因此我将引用我的目录结构作为参考：

现在看看你的错误：

fatal error: 'GL/glew.h' file not found

除非 1.13.0 和 2.0.0 之间的目录结构发生重大更改，否则很明显您会收到此错误，因为“Include”目录的级别低于您的#include语句尝试访问的级别。

如果您替换#include<GL/glew.h>为#include<glew.h>，您的问题应该得到解决。

或者，不要使用 3 个 include 语句，而是重新组织库并将所有标头放在一个位置，然后通过对主 Include 目录的单个引用来引用它们。
