Can't compile GLAD for GLES 2.0; redeclared as different kind of symbol

[devvoid]

Trying to compile a simple OpenGL application with GLAD, but I get a ton of warnings about things being "redeclared as a different kind of symbol".

Here are my settings on the online generator:

Language: C/C++
GL: None
GLES1: None
GLES2: 2.0
GLSC2: None
Specification: OpenGL
Profile: Compatability
No extensions.
Generate a Loader is checked, the other two checkboxes are not.

This happens with a completely empty main.c that does nothing but #include "glad/glad.h" and immediately return 0;. Replacing the ES 2.0 version with 3.3 causes it to compile perfectly.

I can't reproduce this.

Here's a minimal reproduction of the issue:

I still cannot reproduce the issue with your build.

Please share the complete command you're using to compile and all files.

I'm using the included makefile from the zip I uploaded. GCC version is 7.4.0

Here's the full error log I get from trying to build, putting it in a text file because it's pretty long.

After some additional experimentation, I think I've found the actual issue. It seems like including GLAD, and then including GLFW/glfw3.h immediately afterwards is what causes this to happen. If I include one or the other, it works fine.

That's to be expected, glfw includes the gl headers by default. See: https://www.glfw.org/docs/latest/build.html#build_include and define GLFW_INCLUDE_NONE before including glfw.

That worked, thanks for the help!
