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

Question

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.

This is now in the GCC wiki FAQ, see http://gcc.gnu.org/wiki/FAQ#gnu_stubs-32.h

Hmm well I am on ubuntu 12.04 and I got this same error when trying to compile gcc 4.7.2

I tried installing the libc6-dev-i386 package and got the following:

Package libc6-dev-i386 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libc6-dev-i386' has no installation candidate

I also set the correct environment variables in bash:

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)

however, I was still getting the error then I simply copied stubs-32.h over to where gcc was expecting to find it after doing a quick diff:

vic@ubuntu:/usr/include/i386-linux-gnu/gnu$ diff ../../gnu ./
Only in ./: stubs-32.h
Only in ../../gnu: stubs-64.h
vic@ubuntu:/usr/include/i386-linux-gnu/gnu$ sudo cp stubs-32.h ../../gnu/
[sudo] password for vic: 
vic@ubuntu:/usr/include/i386-linux-gnu/gnu$ diff ../../gnu ./
Only in ../../gnu: stubs-64.h
vic@ubuntu:/usr/include/i386-linux-gnu/gnu$

It's compiling now, let's see if it complains more ...

I was getting following error on a fedora 18 box:

---

1. /usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory compilation terminated.

I Installed glibc.i686 and glibc-devel.i686, then compilation failed with following error:

2. /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-redhat-linux/4.7.2/libgcc_s.so when searching for -lgcc_s /usr/bin/ld: cannot find -lgcc_s collect2: error: ld returned 1 exit status

Solution:

I installed (yum install) glibc.i686 glibc-devel.i386 and libgcc.i686 to get rid of the compilation issue.

Now compilation for 32 bit (-m32) works fine.
