Preloading Shared Libraries
As your program executes, it can call the dlopen() function to access code contained in shared libraries. In some cases, you might need to do something from within TotalView that requires you to preload library information. For example, you might need to refer to one of a library’s functions in an eval point or in a Tools > Evaluate command. If you use the function’s name before TotalView reads the dynamic library, TotalView displays an error message.
Use the Tools > Debugger Loaded Libraries command to tell the debugger to open a library.

NOTE: TotalView might not read in symbol and debugging information when you use this command. See Controlling Which Symbols TotalView Reads for more information.
