Compatibility Between HP-UX Releases 10.x and 11.x
Chapter 4450
An executable created by linking with a mixture of shared and
archive libraries is not recommended.
• Data model relocatable object compatibility.
Creating an executable by linking with a mixture of 32-bit and 64-bit
objects is not supported and will not be permitted by the loader.
Compatibility Between 32-bit and 64-bit
There are several areas where compatibility issues may arise between
the 32-bit and 64-bit versions of HP-UX 11.0. These issues are explained
in the following sections:
• “Running 10.x Applications on HP-UX 11.0” on page 450
• “Exchanging Data Between 32-bit and 64-bit Applications” on
page 454
Table 4-3 shows how supported systems interact with the 32-bit and
64-bit versions of HP-UX 11.0.
Running 10.x Applications on HP-UX 11.0
The term binary compatible means that an application that ran on a
previous release will generally continue to run with the same behavior
on the current release. In the great majority of cases, legacy software is
binary compatible with HP-UX 11.0 (that is, it will run successfully). If
