Linux上的OpenGL库链接 [英] OpenGL libraries linkage on linux

问题描述

我编写了一个小OpenGL程序，显示了一个简单的四边形.为了完成这项工作，我在我的Makefile中链接了-lglut.直到这里一切都好.

I coded a small OpenGL program displaying a simple quad. To do the job done, I linked -lglut in my Makefile. Until here all is ok.

这是我的Makefile内容:

Here's my Makefile content :

NAME        =   Quad

CXX     =   g++

SRCS        =   main.cpp

OBJS        =   $(SRCS:.cpp=.o)

CXXFLAGS    +=  -W  -Werror -Wextra

LIBX        +=  -lglut

RM      =   rm  -f

all     :   $(NAME)

$(NAME)     :   $(OBJS)
            $(CXX)  -o  $(NAME) $(OBJS) $(LIBX)

clean       :
            find . \( -name "*.o" -o -name "*~" -o -name "#*#" \) -exec $(RM) {} \;

fclean      :   clean
            $(RM)   $(NAME)

re      :   fclean  all

.PHONY      :   all     \
            clean       \
            fclean      \
            re

但是现在我想与我自己的库资源文件建立链接. 这是我的项目目录的内容:

But now I want to make a linkage with my own librairies resources files. Here's the content of my project directory :

main.cpp
Makefile
Outbuilding/GL/include/glut.h
Outbuilding/GL/lib/glut32.lib

我在main.cpp中的包含声明

My include declaration in main.cpp

#include "gl/glut.h"

我试图编辑以下Makefile，但它不起作用(找不到文件gl/glut.h):

I tried to edit the following Makefile but it does not work (the file gl/glut.h is not found) :

NAME        =   Quad

CXX     =   g++

SRCS        =   main.cpp

OBJS        =   $(SRCS:.cpp=.o)

CXXFLAGS    +=  -W  -Werror -Wextra

INCLUDE     +=  -I./Outbuilding/GL/include -L./Outbuilding/GL/lib
LIBX        +=  -lglut

RM      =   rm  -f

all     :   $(NAME)

$(NAME)     :   $(OBJS)
            $(CXX)  -o  $(NAME) $(OBJS) $(INCLUDE) $(LIBX)

clean       :
            find . \( -name "*.o" -o -name "*~" -o -name "#*#" \) -exec $(RM) {} \;

fclean      :   clean
            $(RM)   $(NAME)

re      :   fclean  all

.PHONY      :   all     \
            clean       \
            fclean      \
            re

我也尝试在源文件中直接链接glut.h(#include"./Outbuilding/GL/include/gl/glut.h")，但出现以下错误:

I also tried in my source file to link directly glut.h (#include "./Outbuilding/GL/include/gl/glut.h") but I have the following error :

error : "APIENTRY" redefined

有人可以帮助我吗?

推荐答案

您的 glut.h 文件位于错误的文件夹中.

Your glut.h file is in the wrong folder.

通常 glut.h 是一个 gl 文件夹，在您的项目中是全局文件夹或本地文件夹.

Normally glut.h is a gl folder, either global or local to your project.

只需在 Outbuilding/GL/include/中创建一个名为* gl8的文件夹，然后将 glut.h 移入其中.

Just create a folder called *gl8 inside Outbuilding/GL/include/ and move the glut.h into it.
