ubuntu fedora arch - Error “gnu/stubs-32.h: No such file or directory” while compiling Nachos source code
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
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
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.
This is now in the GCC wiki FAQ, see http://gcc.gnu.org/wiki/FAQ#gnu_stubs-32.h
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
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.
gnu/stubs-32.h is not directed included in programms. It's a back-end type header file of
gnu/stubs.h, just like
gnu/stubs-64.h. You can install the
multilib package to add both.
If you are facing this issue in Mac-OSX terminal with python, try updating the versions of the packages you are using. So, go to your files in python and where you specified the packages, update them to the latest versions available on the internet.
