When using HP-UX I can use the chatr utility to report on various internal attributes of a shared library. It will also allow me to modify the internal attributes of shared libraries that I have built.
The chatr utility can report, and in some cases modify, such things as:
- the run-time binding behaviour,
- the embedded library path list created at build time,
- whether the library is subject to run-time path lookup,
- internal names,
- etc., etc.
Is such a utility available for Solaris?
Edit: Freaky! Thanks to mark4o's answer below I revisited the elfdump output for a typical system .so (libm.so.2 on Sol 10). However, and here's the freaky part, I mistyped the command to enter:
elfdump libm.so.2 | moe
In an amazing stroke of serendipity, this gave me back the usage message for a utility called moe whose man page description section says:
The moe utility manifests the optimal expansion of a path-name containing reserved runtime linker tokens. These tokens can be used to define dependencies, filtees and runpaths within dynamic objects. The expansion of these tokens at runtime, provides a flexible mechanism for selecting objects and search paths that perform best on this machine.
This will help me resolve why a libm.so.2 shlib is not compatible on both of two different machines leaving my incomplete executable unable to start on one server.
