Hi,
How does one get debug output during startup from things like libroot?
Particularly with launch_daemon.
I tried using dprintf(), but I'm getting undefined references, so
that's probably not usable? And using syslog(), it appears to hang.
And I don't get output when using printf().
Files I want to be able to get printf-style debugging output from are:
src/kits/app/Roster.cpp: BRoster::_LaunchApp
src/system/libroot/os/image.cpp: load_image
With UEFI, I'm finding that the page faults are happening in
load_image. This seems to be related to the __gRuntimeLoader pointer,
but I'd like to be able to do things like print out the address of
__gRuntimeLoader, etc.
I can't use the userland debugger, as it's still too early during startup.
