[okl4-developer] Would you teach the method of debug pistachio/iguana/wombat?

Mon May 28 13:59:17 EST 2007

Hi Tomohiro,

The debug sysmbols will be found in the actual application images, not 
the final image. This is because the debugger won't understand a 
bootimage with multiple applications etc anyway.

Look in the build/iguana/bin  etc directories for the application 
binaries. We would normally tell the debugger to load symbols from those 
files.

regards,
Carl
