GCC: compiling 32bit code on 64bit systems

To be able to compile code correctly on 32bit systems 64bit need to be available on the system also required 32bit libraries.
This version of the libraries (32bit) are not usually installed by default on 64bit systems.

personal experience, when you have compilation problems due to the generation of 32bit applications on 64bit machines, in most cases you can solve the problem by installing these packages on Ubuntu systems (with gcc already installed )

 sudo apt-get install libc6-dev-i386 
 

or alternatively

 sudo apt-get install gcc-multilib on these and 
 

sustem Fedora / RedHat (with gcc already installed): yum install glibc-

 devel.i686 libgcc.i686 
 

If these packages are not installed, typical errors that are obtained during compilation and linking are (in the absence of libc6-dev- glibc-i386 or devel.i686):

 
 [...] / usr / include / gnu / stubs.h: 7:27: error: 
 gnu/stubs-32.h: No such file or directory 
 

and (on systems Fedora / RedHat, in the presence of glibc-devel.i686 but no libgcc.i686):

 [...]/ ld: can not find-lgcc_s 
 
 [...] collect2: ld returned 1 exit status
