[ubuntu] Error “gnu/stubs-32.h: No such file or directory” while compiling Nachos source code



Answers

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
Question

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.







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.




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.
