Known Limitations

Totalview® Reference Guide : PART III Platforms and Operating Systems : Chapter 10 Operating Systems : Debugging Your Program’s Dynamically Loaded Libraries : Known Limitations

Known Limitations

Dynamic library support has the following known limitations:

• TotalView does not deal correctly with parallel programs that call dlopen on different libraries in different processes. TotalView requires that the processes have a uniform address space, including all shared libraries.

• TotalView does not yet fully support unloading libraries (using dlclose) and then reloading them at a different address using dlopen.

Remapping Keys

On the SunOS 5 keyboard, you may need to remap the page-up and page-down keys to the prior and next keysym so that you can scroll TotalView windows with the page-up and page-down keys. To do so, add the following lines to your X Window System startup file:

# Remap F29/F35 to PgUp/PgDn

xmodmap -e 'keysym F29 = Prior'

xmodmap -e 'keysym F35 = Next'

Expression System

Depending on the target platform, TotalView supports:

• An interpreted expression system only

• Both an interpreted and a compiled expression system

Unless stated otherwise below, TotalView supports interpreted expressions only.
