Whenever I try to compile my c program on mac it gives the following error. I am completely clueless about it.
'sys/cdefs.h' file not found
have you installed "Xcode Command Line Tools" ? just install it in your terminal.
sudo xcode-select --install
Install Xcode, if you haven't already.
Then, from Terminal do the following to avoid future similar (not necessary just for this, I don't think) issues in future:
xcode-select --install
This will automatically download and install the latest XCode Command Line Tools.
From Xcode 4.3, the Xcode is installed from Mac App Store. By default, there is no command line tools. Probably you have missed it. They can be installed using the Components tab of the Downloads preferences panel.

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
This is the error I get in VS Code's terminal. There are error squiggles under the "#include <stdio.h>" line.
This is after I upgraded to Mac OS Monterey.
What is the reason for this error and what is the solution?
When upgrading your Mac OS, sometimes the code command-line tools stop working. This can be resolved by running this in the terminal:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
If you don't have Xcode installed you should do:
xcode-select --install
which will install the command-line tools without having Xcode.
The fix, luckily, is pretty straight forward. Install the Xcode toolkit! Even if you had it installed before, you might have to re-register it or update it to the latest version.
$ xcode-select --install
If that doesn’t work, force it to reset. You’ll need sudo access for this one.
$ sudo xcode-select --reset

I followed the tutorial here from the Medium: https://medium.com/#GuruAtWork/setup-fastai-ubuntu-on-windows-10-44ca50b13a9
I was following it well until a MinGW was used for command lines. I am not sure how they went about doing this as the only way I could get nvcc to work is with sudo apt install nvidia-cuda-toolkit. However, this does not seem to complete the same thing as their tool kit is installed as if the exe was just run with Windows. However, that, of course, doesn't work with the Ubuntu. Let me know what you think, thank you.
AFAIK it's just not possible right now to do so from WSL. The link from Medium only sets it up for the Git bash prompt, which is not the same as WSL.
I am running MacOS Mojave Version 10.14.1. I am attempting to install the avr embedded development environment.
The command 'brew tap osx-cross/avr' works correctly however when the command 'brew install avr-libc' is used the following error is produced error
This produces a problem as files in c cannot be compiled due to avr-gcc being unavailable.
Any help and advice would be appreciated.
as #nos said, you need to run brew install avr-gcc.
More info here: https://github.com/osx-cross/homebrew-avr#installing-homebrew-avr-formulae
This worked for me: brew tap osx-cross/avr && brew install avr-gcc
Needed to expand brew's options of available software, as well as reference the updated avr-gcc instead of avr-libc.
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 <stdio.h>
int main(int argc, const char *argv[])
{
printf("Hello, world!");
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?
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
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.
I had the same problem. I installed "XCode: development tools" from the app store and it fixed the problem for me.
I think this link will help:

Credit to Yann Ramin for his advice. I think there is a better solution with links, but this was easy and fast.
Good luck!
I am a beginner, trying to code C on a Mac. I am using Learn C the Hard way By Zed but when I tried running the C code on my Mac it would not run. I have installed Xcode from the mac Appstore but when I try to run my code using the command "make" or "gcc" the terminal responds command not found.
Am I doing something wrong?
I have tried searching for the solution but all of the ones I have found say just to install Xcode and do not give further instructions.
I am just hoping to find out how to test/run my code.
Thanks for the help in advance!
Install the Command line tools via xcode. You just go into preferences and then downloads.
XCode 4.3 Command Line Tools
If you still have troubles after updating xcode or installing command line tools try this install after:

Good Luck!
