- Subject: how to source level debug if I cannot see source embedded in elf file
Dear all:
If my tool chain cannot generate elf file without source embedded even
I compile them with "-g", can I do the source level debugging?
one of my toolchain cannot generate elf file with source embedded in,
I cannot see source code with "objdump -S testprogram.elf|less", but I
can see the function name in the file as the end of letter.
If I can do the source level debug, is there any setting or file I
have to generate?
appreciate your help,
miloody
