Compiling uClibc with MIPS SDE6

Compiling uClibc with MIPS SDE6

[colin]

Hi there,
I encounter a problem when compiling uClibc with SDE6. If compiling with
debug information enabled, the output executable file of busybox is about
the same with the one that is compiled with SDE5, but uClibc libraries are
over 10 times the size of the ones that are compiled with SDE5. I am
wondering if it is because GCC 3.4.4 of SDE6 has changed some parameters
setting?

Regards,
Colin

SDE 6 uses Dwarf-2 debug data, whereas SDE 5 used Stabs. That may
explain the difference.

Hi Nigel,
I had already noticed this difference.
But why the application with debug information is not so big, whereas the
libraries are?
And the SDE 6 document says that using -gstabs flag can make it compile with
STABS debug format.
I replaced -g3 with -gstabs flag when compiling uClibc, but it cannot
compile successfully.

Regards,
Colin
