I get this particular error when compiling a C++ source file which includes stb_image.h.
In file included from /home/zeux/Documents/Projects/cube-game/./lib/stb/stb_image.h:723,

I did not get this error when I directly had
#define STB_IMAGE_IMPLEMENTATION
#include <stb_image.h>
In my main.cpp file.
My setup right now is, I include the stb image header file in a precompiled header, which is configured using CMake, and I include that precompiled header in my main.cpp file. Would this be the issue?
main.cpp file,
#include "./epch.hpp"
/*
Code that uses STB Image
*/
cmake file,
add_executable(App ${app_src})
target_precompile_headers(App PRIVATE src/epch.hpp)
epch.hpp file,
/*Other includes*/
#include <stb_image.h>
/*Other includes*/
stbi_impl.cpp file,
#define STB_IMAGE_IMPLEMENTATION
#include <stb_image.h>
There seems to be a problem with your compiler configuration for SIMD instruction generation. You should first disable SIMD:
#define STBI_NO_SIMD
#define STB_IMAGE_IMPLEMENTATION
#include <stb_image.h>
If the program works correctly, you can try and investigate SSE2 support and add a compiler option -msse2.
