I would recommend to following:

First,
Install "multilib" support. In debian/ubuntu, the command is:
   apt-get install gcc-multilib g++-multilib

With Fedora it should be something equivalent, see here:
   
https://www.cyberciti.biz/tips/compile-32bit-application-using-gcc-64-bit-linux.html


Then,
Assuming you are using gcc, use the following command:
  ./configure CPPFLAGS="-m32" LDFLAGS="-m32" TIME_T_32_BIT_OK=yes
  make

The resulting binaries will then be 32-bit.

The TIME_T_32_BIT_OK is needed due to a recent change that checks
for 64-bit time_t variable.

Cross compiling coreutils to 32 bit

[Kevin Wilson]

Hi,

I am trying to cross compile coreutils-8.27 to 32 bit on
x86_64 machine under Fedora.

What I am running is:
untar the tar file.

./configure --target=i686-pc-linux-gn

and then "make".

It builds succesfully.
However, when I am runing:

file src/stty
I am getting:
src/stty: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
.
...
And likewise for all other generated binaries under src.

I would expect that the generated binary will be 32 bits, as I am
trying to cross compile to 32 bits.
I also tried with to play with:
./configure --host=

 but got the same.

What am I doing wrong ? it could be that I am missing something trivial?

Regards,
KV
