I'm trying to compile a 32-bit C application on RHEL 7 64-bit using gcc 4.8. I'm getting a compiler error /usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory. What do I need to do to get 32 bit apps compiled and linked?

How can I install 32-bit rpm on 64-bit using yum?

So to install the 32-bit library, you have to use an IBM-provided installer script called ibm-yum.sh. If you are an external customer, then use the yum program. Get the ibm-yum.sh script and put it on any temp dir on your system, then use it as shown in the subsequent screenshot steps.

To get RHEL 7 64-bit to compile gcc 4.8 32-bit programs, you'll need to do two things.

  1. Make sure all the 32-bit gcc 4.8 development tools are completely installed:

    sudo yum install glibc-devel.i686 libgcc.i686 libstdc++-devel.i686 ncurses-devel.i686

  2. Compile programs using the -m32 flag

    gcc pgm.c -m32 -o pgm
