64-bit Mode Linker Toolset Compatibility with De Facto Industry Standards
64-bit Mode Linker Toolset
Compatibility with De Facto Industry
Standards
The 64-bit mode linker and dynamic loader provide linking and loading
behaviors found widely across the Unix industry, considered, with the
SVR4 standards, to define the de facto industry standards. The following
64-bit linker behavior is compliant with de facto industry standard:
• ELF object file format and libelf(3x) routines
• Dynamic path searching
• Library-level versioning
• dl* family of dynamic loading routines
• Breadth-first symbol searching
The HP-UX 11.00 release maintains certain behaviors to make
transition from 32-bit to 64-bit mode easier:
• Creation of default run-time path environment variable (RPATH) if no
ld +b is seen on the link line, to improve transition from the 32-bit
mode linker.
• ld +compat option for compatibility with 32-bit linking and loading
behavior.
