macOS 'wchar.h' File Not Found

Question

Under OS X 10.9.5 using XCode 6.0.1 I am running into the following issue when I try to run make from the terminal:

fatal error: \'wchar.h\' fil         


        

Answer 1

xcode-select --install worked for me.

additionally if you're using visual studio code and your intellisense acts weird -

1. make a folder called .vscode in your project root.
2. install vscode extension call C/C++ by microsoft
3. create the c_cpp_properties.json file and paste the below contents

project_dir > .vscode > c_cpp_properties.json

{
    "configurations": [
      {
        "name": "macOS",
        "includePath": ["${workspaceFolder}/**"],
        "defines": [],
        "macFrameworkPath": ["/System/Library/Frameworks", "/Library/Frameworks"],
        "compilerPath": "/usr/bin/clang",
        "cStandard": "c11",
        "cppStandard": "c++17",
        "intelliSenseMode": "${default}"
      }
    ],
    "version": 4
}
