Environment variables

The following environment variables affect the operation of shared libraries:

LD_LIBRARY_PATH
A colon-separated list of directories to search for .so files at run-time. Supplements the rpath built into the application. For more information, see ld(1).
LD_BIND_NOW
If set to any value, procedure bindings are done at startup rather than along the way. Possible run-time link failures will be detected at startup, and there will be no first-call run-time cost.
LD_TRACE_LOADED_OBJECTS
Do not run program, but print which libraries will be required. Do not set this permanently in your environment.
