[U-Boot-Users] Compiling a debug version of U-boot

[Armand Ciejak]

What should I do to build a debug version of U-boot.
I currently add ?#define DEBUG? to the u-boot_1.1.2/include/configs/board_name.h file.
Is it the right method?

I building U-boot for a custom board derived from the MPC8540ADS, and when I start gdb I
get a strange warning. If someone has any idea it would help!

linuxcompiler:~/u-boot/u-boot_1.1.2$ ppc-linux-gdb u-boot
Warning: Cannot initialize solib-absolute-prefix

Normally you would just enable  "-DDEBUG"  in  "config.mk";  in  some
cases  you  may  also  have  to  select a debug version of the linker
script (see the LDSCRIPT definition).  However,  this  enables  DEBUG
globally,  which  usually  is NOT a good idea. It may even crash your
system if you don't know exactly what you're doing.

It's usually better to just enable DEBUG in the specific files you're
interested in.

And which of that is a strange warning?
