ltrace vs Valgrind

Struggling to choose between ltrace and Valgrind? Both products offer unique advantages, making it a tough decision.

ltrace is a Development solution with tags like library, debugging, tracing, dynamic-linking.

It boasts features such as Intercepts and records dynamic library calls made by a process, Can trace calls made by programs to shared libraries, Helps debug issues caused by dynamic linking, Shows parameters passed to library functions and return values, Tracks time spent in each call and pros including Lightweight and easy to use for debugging, Does not require modifying or recompiling the target program, Works on most Linux distributions without special setup, Can trace proprietary programs where source code is unavailable.

On the other hand, Valgrind is a Development product tagged with memory, debugging, profiling.

Its standout features include Memory error detector, Thread error detector, Cache and branch-prediction profiler, Call-graph generating cache and branch-prediction profiler, and it shines with pros like Detects memory management and threading bugs, Open source and free, Available on Linux and macOS, Detailed error reports.

Product Overview

ltrace

Description: ltrace is a debugging utility that intercepts and records dynamic library calls which are called by an executed process. It can be used to trace calls made by programs to shared libraries and helps debug issues caused by dynamic linking.

Valgrind

Description: Valgrind is an instrumentation framework for building dynamic analysis tools. It can detect memory management and threading bugs, and profile programs. Valgrind helps programmers improve code quality by detecting reading/writing of uninitialized memory, memory leaks, and more.
