GCC fatal error: stdio.h: No such file or directory
macOS
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
If you see an error message that developer tools are already installed (and still header files can't be found), wipe out any existing one to do a fresh installation:
sudo rm -rf /Library/Developer/CommandLineTools
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.
ubuntu users:
sudo apt-get install libc6-dev
specially ruby developers that have problem installing gem install json -v '1.8.2'
on their VMs
