Building 32-bit EPICS binaries on 64-bit Linux systems

["Mark Rivers" <rivers@cars.uchicago.edu>]

Folks,

 

I want to build EPICS in 32-bit mode on a 64-bit Linux machine.  I had assumed that all I needed to do was to define EPICS_HOST_ARCH to be linux-x86, rather than linux-x86_64.  But when I do this it creates the expected directories and binaries, e.g. bin/linux-x86/caRepeater, etc. but the binaries appear to be 64-bit.  Running “file” on them reports them at ELF 64-bit files.  My IOC is crashing, and I suspect it is because it is built as a 64-bit application.   How do I force it to be built as a 32-bit application?  This is EPICS R3.14.9.

 

Thanks,

Mark
