The gnu debugger (gdb) can be used to look inside core dumps (called core) from various supported systems [3] it detects problems in a program while letting it run and allows users to examine different registers. The utilities generally provide posix compliant interface when the posixly_correct environment variable is set, but otherwise offers a superset to the standard interface. An elf file has two views The program header shows the segments used at run time, whereas the section header lists the set of sections In computing, the executable and linkable format[3] (elf, formerly named extensible linking format) is a common standard file format for executable files, object code, shared libraries, device drivers, and core dumps
First published in the specification for. Gdbserver is a computer program that makes it possible to remotely debug other programs [1] running on the same system as the program to be debugged, it allows the gnu debugger to connect from another system That is, only the executable to be debugged needs to be resident on the target system (target), while the source code and a copy of the binary file to be debugged reside on the. Kdump is a feature of the linux kernel that creates crash dumps in the event of a kernel crash When triggered, kdump exports a memory image (also known as vmcore) that can be analyzed for the purposes of debugging and determining the cause of a crash
