Introduction to GDB

GDB, the GNU Project debugger, allows you to see what is going on “inside” another program while it executes -- or what another program was doing at the moment it crashed. Note that GDB is most effective when tracing programs and libraries that were built with debugging symbols and not stripped.

This package is known to build and work properly using an LFS-7.6 systemd platform.

Package Information

GDB Dependencies


DejaGnu-1.5.1 (for tests), Guile-2.0.11 and Python-2.7.8

User Notes:

Installation of GDB

Install GDB by running the following commands:

./configure --prefix=/usr --with-system-readline &&

To test the results, issue: make -k check. There are many problems with the test suite. Depends on installed compilers, there are differences if run locally or remotely, a large number of timeouts (there is a variable that can be set to increase time for timeout, but changing it, apparently the total number of tests is not conserved), there are failures associated with system readline 6.x, between others. Unexpected failures are of the order of 2.5%.

Now, as the root user:

make -C gdb install


Installed Programs: gcore, gdb and gdbserver
Installed Library:
Installed Directories: /usr/include/gdb and /usr/share/gdb

Short Descriptions


generates a core dump of a running program.


is the GNU Debugger.


is a remote server for the GNU debugger (it allows programs to be debugged from a different machine).

contains functions for the in-process tracing agent. The agent allows for installing fast tracepoints, listing static tracepoint markers, probing static tracepoints markers, and starting trace monitoring.
