General purpose registers not in core file

General purpose registers not in core file

[Miguel A. Nuñez]

Hello,

  I'm trying to debug a core file but I always get this error (multit is my executable)

[/export/home/miguel]$ gdb multit core
GNU gdb 6.0

This GDB was configured as "sparc-sun-solaris2.9"...

warning: Couldn't find general-purpose registers in core file.


warning: Couldn't find general-purpose registers in core file.

0x0000000000000000 in ?? ()
(gdb) 
(gdb) 
(gdb) quit


  I have compiled my executable using -g (I tried also using -ggdb), but I always get the same error. Can anyone point me to what I'm doing wrong?


Thanks
Miguel Angel

Try using a more recent version of GDB, which has better Solaris
support.

You may also want a 64-bit GDB binary.

Thank you Daniel.

My executable is a 64-bit one. Does this make any difference? Should I use a 64-bit gdb binary?

Yes, absolutely.

Ok!

I got gdb from www.sunfreeware.com, where there are solaris packages ready to install with pkgadd. I will have to make a 64-bits binary from the sources.
