Error to compile Opengl code

Good Afternoon, I use linux and I’m learning OpenGL, but when I go compile my code for that mistake:

/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status

the only code I have is this:

#include <iostream>
#include <GL/glew.h>

and the code I used to compile was this: g++ main.cpp -o main

I already installed the libs:libglm-dev and libglew-dev.

How could I solve.
Use linux Mint 19.3

Missing put Linker options in gcc:

g++ main.cpp -o main -lGLEW

And also define a function int main()

For a complete project you will also need to link at least Opengl with -lGL.

  • Thank you very much, sorry I didn’t answer before, I had a few problems here, I didn’t know I needed the main method to compile, thanks

  • To compile an executable with the option -o have to define int main(). Only when you build an Object file from an eventual dependency you don’t need.
