GCC fatal error stdio h No such file or directory

Question

I m trying to compile a program in C on OS X 10 9 with GCC 4 9  experimental   For some reason  I m getting the following error at compile time  gcc  fatal error  stdio h  No such file or directory  I then tried a simple Hello World program   include  lt stdio h gt   int main int argc  const char  argv          printf  quot Hello  world  quot        return 0     Again  upon running gcc -o   hello   hello c  I got the same error  I m using an experimental version of gcc  but it seems implausible that there would be a release which generated errors upon importing stdio  What could be causing this issue  and how can it be fixed

Mac OS X  I had this problem too  encountered through Macports compilers   Previous versions of Xcode would let you install command line tools through xcode Preferences  but xcode5 doesn t give a command line tools option in the GUI  that so I assumed it was automatically included now  Try running this command   xcode-select --install   Ubuntu   as per this answer   sudo apt-get install libc6-dev   Alpine Linux   as per this comment   apk add libc-dev

Mac OS Mojave  The accepted answer no longer works  When running the command xcode-select --install it tells you to use  Software Update  to install updates   In this link is the updated method   Open a Terminal and then   cd  Library Developer CommandLineTools Packages  open macOS SDK headers for macOS 10 14 pkg   This will open an installation Wizard   Update 12 2019  After updating to Mojave 10 15 1 it seems that using xcode-select --install works as intended

I know my case is rare  but I ll still add it here for someone who troubleshoots it later  I had a Linux Kernel module target in my Makefile and I tried to compile my user space program together with the kernel module that doesn t have stdio  Making it a separate target solved the problem
