It has been weeks that I am trying to use Code::Blocks IDE on Ubuntu 14.04 LTS to program Atmega16, however I am hindered by the following error while compiling/building the program in C::B

/usr/include/features.h|374|fatal error: sys/cdefs.h: No such file or directory|

I have read this thread and based on that I have tried to purge libc6-dev and ran into trouble by removing the dependencies. From previous experience I knew that there is a huge probability to get into broken pipe error. I tackled it by installing the lost dependencies.

Now still I have the same error.

If you are on an amd64 installation, you can try to install the package libc6-dev-i386. This helped me solve the same issue you encountered while trying to compile smm from i8kutils.

On my machine, where I've probably screwed around too much with 32 and 64 bit architecture files, I resolved this issue by installing g++-multilib.

Typing the command:

sudo apt-get --reinstall install libc6 libc6-dev

solved the problem.

Looks like sys/cdefs.h is defined under /usr/include/x86_64-linux-gnu/sys, but /usr/include/x86_64-linux-gnu is NOT a default INCLUDE_PATH.

I know this is an Ubuntu-centric branch of but this page is the first one that came up when I searched this error on Google (even when I put -Ubuntu in the search), so I'm going to share my answer for Arch linux here:

In Arch, I got a /lib/cpp fail sanity check because the package glibc was corrupt and missing all the /usr/include/sys headers. I resolved this error by recompling glibc.

apt install gcc-multilib will also install the library you need libc6-dev-i386 along with packages you might need in future.

I got this while trying to compile openssl-1.0.2a while chrooted to a wheezy 32-bit partition while running a 64-bit kernel. the "./config" script was too smart, and decided to configure for amd64. I solved it by MACHINE=i386 ./config --prefix=$HOME, and then make worked without error.

I got this by accidently adding the -m32 option (gcc told me to add for -maes but it was wrong).
