The DER_DBG_PATH environment variable is used by the debug engine, the debugger user interface, or both to locate debug source files on your client workstation that are not stored in the same location as the executable being debugged. For example, if your debug executable is stored in F:\BUILDS\SANDDUNE\TEST but your source code is stored in F:\SOURCE and F:\SOURCE\INCLUDE, you should set your DER_DBG_PATH variable as follows:
set DER_DBG_PATH=F:\SOURCE;F:\SOURCE\INCLUDE
You can set the DER_DBG_PATH environment variable on both client and server systems. The search for source files starts on the server first.
Note: The DER_DBG_PATH environment variable must be set on both the client and server systems before starting the Distributed Debugger user interface daemon.
