32-Bit and 64-Bit Applications
in a 64-Bit System
Environment
SUSE Linux Enterprise® is available for several 64-bit platforms. This does not neces-
sarily mean that all the applications included have already been ported to 64-bit plat-
forms. SUSE Linux Enterprise supports the use of 32-bit applications in a 64-bit system
environment. This chapter offers a brief overview of how this support is implemented
on 64-bit SUSE Linux Enterprise platforms. It explains how 32-bit applications are
executed (runtime support) and how 32-bit applications should be compiled to enable
them to run both in 32-bit and 64-bit system environments. Additionally, find information
about the kernel API and an explanation of how 32-bit applications can run under a 64-
bit kernel.
NOTE: 31-Bit Applications on IBM System z:
s390 on IBM System z uses a 31-bit environment. References to 32-bit applica-
tions in the following also apply to 31-bit applications.
SUSE Linux Enterprise for the 64-bit platforms ia64, ppc64, s390x, and x86_64 is de-
signed so that existing 32-bit applications run in the 64-bit environment "out-of-the-
box." The corresponding 32-bit platforms are x86 for ia64, ppc for ppc64, s390 for
s390x, and x86 for x86_64. This support means that you can continue to use your pre-
ferred 32-bit applications without waiting for a corresponding 64-bit port to become
available. The current ppc64 system runs most applications in 32-bit mode, but you
can run 64-bit applications.
