Debugging best practices under Linux?

[Norbert Kiesel <nkiesel@...>]

Hi,

today I again went for my yearly hunt for a decent Lua debugger running
under Linux.  Despite trying various tools, so far I always went back to
sprinkling my code with print statements because nothing else really
worked for me.  What I'm looking for (in decreasing order of importance
for me):
 - local command-line debugging (e.g. "lgdb foo.lua")
 - debugging embedded Lua code running within my C++ program
 - integrated C++ and Lua debugging
 - GUI

What are you using?

Best,
  Norbert
