Debugging your applications with glibc. This article describes some of the features of the GNU C library (glibc 2.1) version 2.1 (or higher), which will prove very useful when debugging applications and libraries. These features offer additional debugging possibilities that normal debuggers like gdb or trace utilities like strace and ltrace do

Introduction. The scope of thi wiki is to guide the user throught the already existing Xilinx's documentation. Since this is well done and continuosly updated, SECO provides a road in using the Xilinx eco-system with the SECO's BSP in order to have a full support to SECO's boards. Along this wiki the user will find references to specific guides provided by Xilinx, coded with unique key.

Sep 17, 2016 · In this post, I will attempt to explain the inner workings of how dynamic loading of shared libraries works in Linux systems. This post is long - for a TL;DR, please read the debugging cheat sheet.. This post is not a how-to guide, although it does show how to compile and debug shared libraries and executables. It's optimized for understanding of the inner workings of how dynamic loading works.

Debugging/Getting traces. This article aims to help in creating a debugging Arch package and using it to provide trace and debug information for reporting software bugs to developers. Usually, executable files are stripped of human readable context to make them smaller. Not only that, enhanced debugging information is usually not added to the

Debugging the Loader. This page describes different methods for debugging the GLIBC dynamic linker/loader ld[64].so to achieve certain goals. There are several loader environment scenarios: Loader is in the system toolchain, e.g. /lib[64]/ld[64].so.1 ; Loader is in a self-contained toolchain, e.g. /opt/toolchain/lib[64]/ld[64].so.1

Since it seems impossible to do just with symbol versioning hacks, let's go one step further and compile glibc ourselves. This setup might work and is quick as it does not recompile the whole GCC toolchain, just glibc.

Mar 21, 2021 · The above procedure will install the debug symbol package for a single package only. Chances are that the binary uses shared libraries in other packages and debug symbols for them might be required in order to obtain a readable stack trace or perform other debugging tasks. You can use the 'find-dbgsym-packages' command from the 'debian-goodies

Some other debugging tools have been designed to work with GDB, such as memory leak detectors. Internals. GDB uses a system call named ptrace (the name is an abbreviation of "process trace") to observe and control the execution of another process, and examine and change the process's memory and register. A list of common gdb commands and

Mar 12, 2012 · This is primarily used to provide extra malloc debugging features. These extended malloc debugging features are not available within uClibc. There are many good malloc debugging libraries available for Linux (dmalloc, electric fence, valgrind, etc) that work much better than the glibc extended malloc debugging.

The routines used for stack checking are actually part of glibc, but gcc is patched to enable linking against those routines by default. Heap Protector. The heap protector provides double-free/overflow protections to the glibc heap memory manager (first introduced in glibc 2.3.4). This stops the ability to perform arbitrary code execution via
