I recently upgraded xcode command line tools to version 2384. After this I decided to reinstall gcc which was installed with homebrew. Installation completed with no errors but when I tried to compile a simple code with iostream library, it gave an error saying:
/usr/local/Cellar/gcc/10.2.0/include/c++/10.2.0/cwchar:44:10: fatal error: wchar.h: No such file or directory
Later, I checked the library folder and there were multiple files missing such as assert.h. I want to ask is there any way to fix this other than installing every file one by one? I already tried updating homebrew and xcode command line tools.
