Runtime environment variables

The following environment variables are used by the system loader or by your application when it is executed.

All of these variables are optional.

LIBPATH

Specifies an alternative directory search path for dynamically linked libraries at application run time. If shared libraries required by your application have been moved to an alternative directory that was not specified at link time, and you do not want to relink the executable, you can set this environment variable to allow the dynamic linker to locate them at run time. For more information about this environment variable, see your operating system documentation.

MALLOCALIGN=16

Specifies that dynamic memory allocations return 16-byte aligned addresses.
