在Maverick上使用GLFW3的C ++代码:glShaderSource没有匹配功能 [英] C++ code using GLFW3 on Maverick: glShaderSource no matching function

问题描述

我正在尝试使用Mac上的GLFW3库来编译一个相当简单的C ++程序.操作系统为OS 10.9.3(Maverick).在我尝试使用glSLderSource等GLSL函数之前，它可以正常编译.

I am trying to compile a fairly simple C++ program using the library GLFW3 on Mac. The OS is OS 10.9.3 (Maverick). It compiles fine until I try to use GLSL functions such as glShaderSource, etc.

以下是我使用的包含文件:

Here are the include files I use:

#include <GLFW/glfw3.h>
#include <cstdlib>
#include <cstdio>

我正在使用OpenGL3.2:

I am using OpenGL3.2:

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

以下是用于编译程序的命令行:

Here is the command line to compile the program:

clang++ -o xxxx xxxx.cpp  -framework Cocoa -framework OpenGL  -Wall -lglfw3 -I/usr/local/include/ -L/usr/local/lib  -framework Quartz -framework IOKit

现在出现错误:

xxxx:38:5: error: no matching function for call to 'glShaderSource'
    glShaderSource(vertexShader, 1, &vertexSource, NULL);

我确定我缺少一些基本的知识，但是呢?谢谢你的帮助.我担心它与glext有关，但不确定该怎么做.我在网上的Stackoverflow上找不到任何东西.

I am sure I missing something basic but what? Thanks for your help. I fear it has something to do with glext but not sure what to do really. I couldn't find anything on Stackoverflow on the web.

推荐答案

在OS X上，您需要包括<OpenGL/gl3.h>以获得GL3 +级别入口点的定义.

On OS X, you need to include <OpenGL/gl3.h> to get definitions for GL3+ level entry points.

在GLFW文档中，在构建使用GLFX的程序"页面上， ( http://www.glfw.org/docs/latest/build.html)，有一个名为"GLFW标头选项宏"的部分.相关部分为:

In the GLFW documentation, on the page "Building programs that use GLFX" (http://www.glfw.org/docs/latest/build.html), there is a section named "GLFW header option macros". The relevant sections are:

这些宏可能在包含GLFW标头之前定义，并且会影响标头的行为.

These macros may be defined before the inclusion of the GLFW header and affect the behavior of the header.

GLFW_INCLUDE_GLCOREARB使标头包含现代的GL/glcorearb.h标头(在OS X上为OpenGL/gl3.h)，而不是常规的OpenGL标头.

GLFW_INCLUDE_GLCOREARB makes the header include the modern GL/glcorearb.h header (OpenGL/gl3.h on OS X) instead of the regular OpenGL header.

因此，以下方法可以解决问题:

So the following should do the trick:

#define GLFW_INCLUDE_GLCOREARB
#include <GLFW/glfw3.h>

查看glfw3.h标头( http://www.glfw.org/docs/latest/glfw3_8h_source.html )确认此附加定义中将包含<OpenGL/gl3.h>.

Looking at the glfw3.h header (http://www.glfw.org/docs/latest/glfw3_8h_source.html) confirms that it will include <OpenGL/gl3.h> with this additional define.
