Error "gnu/stubs-32.h: No such file or directory" while compiling Nachos source code

I am trying to install Nachos on my laptop and I have Ubuntu 11.04 on the laptop.

The code is in C and so to build it I assume I will need cross compiler. This is where my problem is. I downloaded the source code of the MIPS cross compiler using the command

  wget http://mll.csie.ntu.edu.tw/course/os_f08/assignment/mips-decstation.linux-xgcc.gz

and I unzipped it using

tar zxvf mips-decstation.linux-xgcc.gz      

This is okay, but when I try to build the source code of the nachos os, using make, I get this error -

/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory compilation terminated. make: *** [bitmap.o] Error 1

I am trying to follow the instructions given over here - http://mll.csie.ntu.edu.tw/course/os_f08/217.htm and everything is working fine except when I try to use make.

You're missing the 32 bit libc dev package:

On Ubuntu it's called libc6-dev-i386 - do sudo apt-get install libc6-dev-i386. See below for extra instructions for Ubuntu 12.04.

On Red Hat distros, the package name is glibc-devel.i686 (Thanks to David Gardner's comment).

On CentOS 5.8, the package name is glibc-devel.i386 (Thanks to JimKleck's comment).

On CentOS 6 / 7, the package name is glibc-devel.i686.

On SLES it's called glibc-devel-32bit - do zypper in glibc-devel-32bit.

On Gentoo it's called sys-libs/glibc - do emerge -1a sys-libs/gcc [source] (Note : One may use equery to confirm this is correct; do equery belongs belongs /usr/include/gnu/stubs-32.h)

On ArchLinux, the package name is lib32-glibc - do pacman -S lib32-glibc.

Are you using Ubuntu 12.04? There is a known problem that puts the files in a non standard location. You'll also need to do:

export LIBRARY_PATH=/usr/lib/$(gcc -print-multiarch)
export C_INCLUDE_PATH=/usr/include/$(gcc -print-multiarch)
export CPLUS_INCLUDE_PATH=/usr/include/$(gcc -print-multiarch)

somewhere before you build (say in your .bashrc).

If you are also compiling C++ code, you will also need the 32 bit stdc++ library. If you see this warning:

.... /usr/bin/ld: cannot find -lstdc++ ....

On Ubuntu you will need to do sudo apt-get install g++-multilib

On CentOS 5 you will need to do yum install libstdc++-devel.i386

On CentOS 6 you will need to do yum install libstdc++-devel.i686

Please feel free to edit in the packages for other systems.

From the GNU UPC website:

Compiler build fails with fatal error: gnu/stubs-32.h: No such file or directory

This error message shows up on the 64 bit systems where GCC/UPC multilib feature is enabled, and it indicates that 32 bit version of libc is not installed. There are two ways to correct this problem:

• Install 32 bit version of glibc (e.g. glibc-devel.i686 on Fedora, CentOS, ..)
• Disable 'multilib' build by supplying "--disable-multilib" switch on the compiler configuration command

Try doing a sudo apt-get install libc6-dev.

apt-file tells me that the file in question belongs to that package.
