fatal error: stdio.h: No such file or directory

I still have a problem linking gcc with stdio.h on my mac. However, I have found an alternative way to compile the program with gcc. I typed brew install gcc in my terminal, that means a new gcc8.0.2 will be installed.(which is my case, I don't know what gcc you will get) Then I use gcc-8 instead of gcc to compile my program. In this way, the new gcc8.0.2 is invoked.

You can check the command name for gcc variants by going to /usr/local/bin All the names for gcc commands are listed there. As for me, those are

g++                 
g++-8               
gcc                 
gcc-8

If you have further question, you can contact me and I will give more details.

I have a problem with #include <stdio.h> on mac Mojave 10.14.1

I have a default gcc compiler together with other gcc compilers.
```
DorothyeMacBook:Desktop dorothy$ which gcc
/usr/local/bin/gcc
```
The version is
```
DorothyeMacBook:Desktop dorothy$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-apple-darwin15.6.0/7.1.0/lto-wrapper
Target: x86_64-apple-darwin15.6.0
Configured with: ../gcc-7.1.0/configure --enable-languages=c++,fortran
Thread model: posix
gcc version 7.1.0 (GCC) 
```
Now I am in the path : /Users/dorothy/Desktop

I have stdio.h in the lib
```
DorothyeMacBook:Desktop dorothy$ find /usr -name "stdio.h"
find: /usr/sbin/authserver: Permission denied
/usr/local/include/c++/7.1.0/tr1/stdio.h
/usr/local/include/c++/4.9.2/tr1/stdio.h
/usr/local/lib/gcc/x86_64-apple-darwin15.6.0/7.1.0/include/ssp/stdio.h
/usr/local/lib/gcc/x86_64-apple-darwin14.0.0/4.9.2/include/ssp/stdio.h
/usr/local/Cellar/gcc/8.2.0/include/c++/8.2.0/tr1/stdio.h
/usr/local/Cellar/gcc/8.2.0/lib/gcc/8/gcc/x86_64-apple-darwin18.2.0/8.2.0/include/ssp/stdio.h
/usr/local/Cellar/gcc/8.2.0/lib/gcc/8/gcc/x86_64-apple-darwin18.2.0/8.2.0/include-fixed/stdio.h
```
However when I compile the file under the current path /Users/dorothy/Desktop Terminal will give me an error:
```
DorothyeMacBook:Desktop dorothy$ gcc  inverse.c -o inv
inverse.c:1:10: fatal error: stdio.h: No such file or directory
 #include <stdio.h>
          ^~~~~~~~~
compilation terminated.

  Seems kind of strange that gcc was built only for c++ and fortran but you are trying to use it as a c compiler. If you rename inverse.c to inverse.cpp does it work?

  Configured with: ../gcc-7.1.0/configure --enable-languages=c++,fortran Yeah this looks odd, mine has c in this list, and without it I can't tell if stdio.h would be supported. Judging from the error message I'd say it is not.

  Did you install xcode?

  @JonathanLeffler: Why do you think this us a duplicate? There are many ways software installations can be messed up. The issue there appeared to have been a broken Xcode/Apple tools installation. This question seems to involve some GCC version, which is different (Apple uses Clang now).

  @EricPostpischil: Because the symptoms are the same — upgraded to Mojave and … No stdio.h was how I encountered the problem.
- Eric Postpischil over 5 years
  
  @JonathanLeffler: The question does not indicate there was an upgrade to Mojave from a previous macOS version, just that 10.14.1 is the version the issue is occurring on. And a comment has identified a likely cause: The GCC installation was configured for C++ and FORTRAN and hence does not support C.

  See Can't compile C program on a Mac after upgrade to Mojave for a probable solution to your problem. Not everyone agrees that your trouble will be resolved by the steps there, though I strongly suspect that what you're seeing is what I saw, and what the OP of that question saw — the system headers have been removed from /usr/include by Apple during an upgrade to Mojave.

  @Jonathan Leffler: Hi, according to your tip, I jumped to the "Can't compile C program on a Mac after upgrade to Mojave ". Then I tried to install the package (macOS_SDK_headers_for_macOS_10.14.pkg)

  @Jonathan Leffler: However, terminal gives me this error:Error: macOS_SDK_headers_for_macOS_10.14.pkg: undefined method `xar!' for Formulary::FormulaNamespace03a5542d706800cf492f2f8aead0a0ff:‌Module

  @Jonathan Leffler: Could you give me more advice and I was checking the release notes from Apple but not big help.
