Trying to run c on vscode in mac, but stdc .h library not found

fatal error: 'bits/stdc  .h' file not found

CodePudding user response：

stdc .h setup on mac (without xcode)

Assuming that you've installed the homebrew and C/C compiler extension. Then follow the steps. As the bits/stdc is a GNU GCC extension, where OSX uses the clang compiler.

• brew install gcc

• gcc --version

• go to the /Library/Developer/CommandLineTools/usr/include directory (go to finder, type command shift g, then paste the directory name)

• create a folder named bits inside this directory and then copy the stdc .h file from this github link (https://github.com/gcc-mirror/gcc/blob/master/libstdc++-v3/include/precompiled/stdc++.h).

• create a file naming bits/stdc .h inside the bits folder and paste the code copied from the github link into bits/stdc .h file, then save it.

• then initially after restarting vscode, some user get a error message as some library is deprecated in stdc .h. for dismissing that error, you should add the gcc library's path to c_cpp_properties.json file's includePath.

• ("/usr/local/Cellar/gcc/12.2.0/include/c /12", "/usr/local/Cellar/gcc/12.2.0/include/c /12/x86_64-apple-darwin21")

You can get this path by hovering on your #include file on code too. add these two path to your includePath section inside of C_cpp_properties.json file. make sure your compilerPath is "/usr/bin/clang"

I am giving the c_cpp_properties.json initial file here for your understanding.
