Errors in Dev-C++

[tupac]

I used to use MSVC++ to do some OpenGL work, but switched to Dev-C++ because you can get it for free, and since i use all different computers i can't keep installing MSVC++ everywhere. so i started using Dev-C++, and i realized that it was very different than using visual c++. i made some code, and tried to run it, but got 4 errors (in MSVC++ this code would compile no prob.). the code is here (this code is to make a basic openGL window):

code:

#include <windows.h> #include <GL/gl.h> #include <GL/glu.h> #include <GL/glut.h> void disp(void){      glClearColor(0.0,0.0,0.0,1.0);      glClear(GL_COLOR_BUFFER_BIT);      glLoadIdentity();      gluLookAt(0.0,0.0,5.0,0.0,0.0,0.0,0.0,1.0,0.0);      glutSwapBuffers();      glFlush(); } void reshape(int w, int h){      glViewport(0,0,(GLsizei)w,(GLsizei)h);      glMatrixMode(GL_PROJECTION);      glLoadIdentity();      gluPerspective(60,(GLsizei)w/(GLsizei)h,1.0,100.0);      glMatrixMode(GL_MODELVIEW); } int main(int argc, char** argv){     glutInit(&argc,argv);     glutInitDisplayMode(GLUT_DOUBLE);     glutInitWindowSize(500,500);     glutInitWindowPosition(0,0);     glutCreateWindow("ogl win");     glutDisplayFunc(disp);     glutIdleFunc(disp);     glutReshapeFunc(reshape);     glutMainLoop();     return 0; }

and i get errors saying:

code:

Untitled2.o(.text+0x1c):Untitled2.cpp: undefined reference to `__glutInitWithExit@12' Untitled2.o(.text+0x3d):Untitled2.cpp: undefined reference to `__glutCreateWindowWithExit@8' Untitled2.o(.text+0x5d):Untitled2.cpp: undefined reference to `__glutCreateMenuWithExit@8' collect2: ld returned 1 exit status make.exe: *** [Project1.exe] Error 1 Execution terminated

does anyone know what's wrong? cuz i've been trying to find out, and it's just been a living hell.

thnx in advance

It's a linkter error, from the looks of it not all teh glut functions are being linked. Did you add the glut to your linker line? Since your using Dev-C++ I dunnot how to do this, but using make files it's pretty easy.

The MSVC++ compiler is free to download and use from Microsoft.

You can set up Dev-C++ to use the VC++ compiler if you want, or simply compile via command line.

It's pretty much the Visual Studio IDE that requires payment, not necessarily all the compilers.

wow, i didnt know that i could use MSVC++ compiler in Dev-C++. well, im gonna try it out l8er cuz i dont have dev here @ the moment, but ill put an update if it worked or not.

thnx for all the help

I'm pretty sure you can link the IDE to different compilers...
If nothing else, there's always the command line option if you want that specific compiler

The compiler you use should not help much, if it's a link error.

Alright, now that I'm on the computer with Dev-C++...

To fix the linker error, go to: Project -> Project Options -> Parameters -> Linker and add the appropriate linker options there.

ya, so i figured it out, all i had 2 do was just download a "glut" kit, and just intall it. the kit out all the stuff that i need to program glut, so now i just open my Dev-c++, choose file>new>project>multimedia>glut, and after doing that, i can just write the same code as i would in MSVC++

well, thnx a lot for all ure relpies
