The processor is armv4 family. I tweak elf_core_dump function of linux kernel 2.6.23. I tweaked the kernel to dump only elf note, registers and stack segments of the running process. But gdb fails to load required shared object files and fails to give the backtraces of the running process. Could you please help me ascertain how gdb loads the required libraries from the core dump. Which ELF section of the core contains the information ? Thanks in Advance, -Abhijit
