Gentle People:

   I am having trouble getting GDB breakpoints
to work on Solaris 64 bit executables.

   Have any of you seen this problem? If yes
what was the work around?

   Are there better debuggers for Solaris 64 bit
executables?

   What debugger do the 64 bit developers use?

   Also please note any Users Manuals for alternate
debuggers.

   Your help will be greatly appreciated.

Thomas Dineen

I thought this was one of the selling points for Sun's compilers and 
tools.  Back when gcc didn't do 64-bit very well (3.0 IIRC), Sun was the 
only game in town for 64-bit compiles.

I take it you built gcc and gdb on a Ultra running a 64-bit kernel.  
Isn't the error message "no debugging symbols found" from compiling 
without "-g"?  What happens if you build test_hello_new64 with -g?

The 64-bit developers at Sun usually use the dbx debugger included with
the Sun Studio compilers, or the mdb debugger included with the OS.
(dbx is more like gdb - mdb takes a lot more work to learn and is more of
a forensic debugger than an interactive one, but is better suited for
kernel debugging.  I normally use dbx unless there's an mdb plugin
module I need to use, simply because that's what I know best.)
