I have a program that worked on my computer before I wiped the hard drive and reinstalled the operating system. I reinstalled all the necessary compilers and DLLs but im getting linker errors for glut. below is a snippet of the code I am trying to run and what my compile command is.
Here is the main I am trying to run:
/*
* GL01Hello.cpp: Test OpenGL C/C++ Setup
*/
#include <windows.h> // For MS Windows
#include <GL/freeglut.h> // GLUT, includes glu.h and gl.h
/* Handler for window-repaint event. Call back when the window first appears and
whenever the window needs to be re-painted. */
void display() {
glClearColor(0.0f, 0.0f, 0.0f, 1.0f); // Set background color to black and opaque
glClear(GL_COLOR_BUFFER_BIT); // Clear the color buffer
// Draw a Red 1x1 Square centered at origin
glBegin(GL_QUADS); // Each set of 4 vertices form a quad
glColor3f(1.0f, 0.0f, 0.0f); // Red
glVertex2f(-0.5f, -0.5f); // x, y
glVertex2f( 0.5f, -0.5f);
glVertex2f( 0.5f, 0.5f);
glVertex2f(-0.5f, 0.5f);
glEnd();
glFlush(); // Render now
}
/* Main function: GLUT runs as a console application starting at main() */
int main(int argc, char** argv) {
glutInit(&argc, argv); // Initialize GLUT
glutCreateWindow("OpenGL Setup Test"); // Create a window with the given title
glutInitWindowSize(320, 320); // Set the window's initial width & height
glutInitWindowPosition(50, 50); // Position the window's initial top-left corner
glutDisplayFunc(display); // Register display callback handler for window re-paint
glutMainLoop(); // Enter the infinitely event-processing loop
return 0;
}
And here is the command that is being run:
g++ GL01Hello.cpp -o GL01Hello.exe -lglu32 -lopengl32 -lfreeglut
and the errors I am getting are all below:
g++ GL01Hello.cpp -o GL01Hello.exe -lglu32 -lopengl32 -lfreeglut

Any help in resolving these linker errors would be extremely helpful.
Edit: I edited all the code above to be a very simple example, and I am still getting a very similar linker error. Someone reported this as a similar problem to the generic "what causes linker errors" Post and I have already tried many of those and none of them have helped. Thank you fo the attempt though
Well, everything you do looks right. My best bet is, that the build of FreeGLUT you're using (specifically the .def and .lib linker stubs) don't match (possibly also the .dll). My suggestion would be, to build FreeGLUT from sources using the very same compiler you're also using to build your program. Try that, and report on any differences.
