Mac + Netbeans C ++ OpenGL问题

Question

I am trying to develop OpenGL programs with C++ on Mac using Netbeans, and there are some compilation errors:

"/usr/bin/make" -f nbproject/Makefile-Release.mk QMAKE= SUBPROJECTS= .build-conf "/usr/bin/make" -f nbproject/Makefile-Release.mk dist/Release/GNU-MacOSX/sdl_test mkdir -p build/Release/GNU-MacOSX rm -f build/Release/GNU-MacOSX/main.od g++ -c -O2 -MMD -MP -MF build/Release/GNU-MacOSX/main.od -o build/Release/GNU-MacOSX/main.o main.cpp main.cpp:9:41: warning: OpenGL.framework/Headers/gl.h: No such file or directory

my code is as simple as this:

#include <iostream>
#include <OpenGL.framework/Headers/gl.h>

/*
 * 
 */
int main(int argc, char** argv) {
    std::cout << glGetString(GL_VERSION) << std::endl;

    return 0;
}

the compiler cannot find OpenGL header file even if I have added the including path and lib file in the project settings. This is really confusing..

Answer 1

In your project properties go to C++ Compiler . Under Include Directories add /System/Library/Frameworks . Under Linker at the bottom under Additional Options add -framework OpenGL .

Change your include directive to #include <OpenGL/gl.h>

Now you should be able to compile your program. But I seem to be missing something, because I get a segmentation fault, when I call glGetString ...

#include <iostream>
#include <OpenGL/gl.h>

int main(int argc, char** argv) {
    const GLubyte* version = glGetString(GL_VERSION); // segmentation fault

    return 0;
}

Answer 2

Your compiler can't Find the referenced header file in it's search path. Try to find the file manually on your hard disk, then ensure your compiler has that location in it's search path.
