Vxworks Ld_path Environment Variable [ EXCLUSIVE → ]

If myApp.vxe depends on shared libraries located in /ata0a/app/lib/ , the loader might fail to find them unless they are explicitly pathed or copied to the same directory.

This is the most common method for debugging and manual operations. vxworks ld_path environment variable

/* Syntax for setting search paths in the current shell context */ -> putenv ("LD_LIBRARY_PATH=/sd0:1/libs:/romfs/usr/lib") Use code with caution. If myApp

Scripts designed to load applications become more portable. You can move your binaries to a different storage mount point (e.g., from /sd0 to /ata0 ) and simply update the environment variable. You do not need to rewrite your loading scripts. Scripts designed to load applications become more portable

This article explores the functionality, configuration, and best practices for using LD_PATH in VxWorks development.

When you initiate a load operation—typically using ld or moduleLoad —and specify a filename without an absolute path, the system consults LD_PATH to locate the file.

VxWorks provides separate host-side development tools and target-side runtime environments to manage variables. 1. Setting Variables via the Target Shell
