How to fix XCode invivisble Headers and Clang compiler issue in MacOS?
Question
GCC- Apple clang version 11.0.3 (clang-1103.0.32.29) is giving me weird results when I try to run any C++/C program. For example, running this code:
#include <string>
#include <iostream>
int main()
{
std::string hello = "Hello world";
std::cout << hello << std::endl;
return 0;
}
I run with gcc or g++
gcc template.cpp -o template
It gives me this error

I think I caused this when I was trying to copy some library header files to /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1
Now I am unable to compile any C++ program on my Mac. I can't understand how to fix this.
I tried installing llvm and adding it's path but nothing helps.

libffi is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
For compilers to find libffi you may need to set:
export LDFLAGS="-L/usr/local/opt/libffi/lib"
export CPPFLAGS="-I/usr/local/opt/libffi/include"

Well, I found a solution. Earlier I was using XCode Application and I messed up some library files when I was trying to copy header files to /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1
It turned so fatal that I was totally helpless. Neither my C++ or C code would compile, nor Node Applications would build due to gyp .
Apparently it some more errors, when I tried to reinstall few things and my homebrew gave a page full of errors with unbrewed header files.
Solution:
I removed Xcode Application, switched to Command line tool. Removed llvm, and it worked.
You need to switch the XCode path, you do it by:
sudo xcode-select --switch /Library/Developer/CommandLineTools
You are good to go, and never mess up with the files inside SDK, else it will cost you hours of panic. Cheers.

I had to re-install the xcode tools for some weird reason...
sudo rm -rf $(xcode-select -print-path)
xcode-select --install

I had similar issues building a meteor app that had a node-gyp dependency, in the end I was able to follow the instructions here to get the build to work
Specifically exporting this flag:
export LDFLAGS=-L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib
The failure looked like
> bufferutil@4.0.4 install /Users/ben.ritchie/Documents/dev/connect4/connect4mvp/node_modules/bufferutil
