c++ - Opengl superbible example compliation errors Source code: drawing a triangle -

i new opengl , i'm trying examples in book, i've included libraries , headers correctly, seems there still not going right.

these headers included :

this code :

// triangle.cpp // our first opengl program draw triangle on screen. #include <gltools.h> // opengl toolkit #include <glshadermanager.h> // shader manager class #ifdef __apple__ #include <glut/glut.h> // os x version of glut #else #define freeglut_static #include <gl/glut.h> // windows freeglut equivalent #endif glbatch trianglebatch; glshadermanager shadermanager; /////////////////////////////////////////////////////////////////////////////// // window has changed size, or has been created. in either case, need // use window dimensions set viewport , projection matrix. void changesize(int w, int h) {     glviewport(0, 0, w, h); } /////////////////////////////////////////////////////////////////////////////// // function needed initialization on rendering context. // first opportunity opengl related tasks. void setuprc() {     // blue background     glclearcolor(0.0f, 0.0f, 1.0f, 1.0f );     shadermanager.initializestockshaders();     // load triangle     glfloat vverts[] = { -0.5f, 0.0f, 0.0f,         0.5f, 0.0f, 0.0f,         0.0f, 0.5f, 0.0f };     trianglebatch.begin(gl_triangles, 3);     trianglebatch.copyvertexdata3f(vverts);     trianglebatch.end(); } /////////////////////////////////////////////////////////////////////////////// // called draw scene void renderscene(void) {     // clear window current clearing color     glclear(gl_color_buffer_bit | gl_depth_buffer_bit | gl_stencil_buffer_bit);     glfloat vred[] = { 1.0f, 0.0f, 0.0f, 1.0f };     shadermanager.usestockshader(glt_shader_identity, vred);     trianglebatch.draw();     // perform buffer swap display buffer     glutswapbuffers(); }  /////////////////////////////////////////////////////////////////////////////// // main entry point glut based programs int main(int argc, char* argv[]) {     gltsetworkingdirectory(argv[0]);     glutinit(&argc, argv);     glutinitdisplaymode(glut_double | glut_rgba | glut_depth | glut_stencil);     glutinitwindowsize(800, 600);     glutcreatewindow(“triangle”);     glutreshapefunc(changesize);     glutdisplayfunc(renderscene);     glenum err = glewinit();     if (glew_ok != err) {         fprintf(stderr, “glew error: %s\n”, glewgeterrorstring(err));         return 1;     }     setuprc();     glutmainloop();     return 0; }

you using "pretty quotes" in code.

c++ expects specific character " used double quote. may not replaced similar-looking characters.

change:

“triangle” , “glew error: %s\n”

to:

"triangle" , "glew error: %s\n"
