Overview

• Valgrind is a powerful and widely used memory profiling tool suite. (http://www.valgrind.org)
• This project aims to provide a useful integration of Valgrind tools with your Eclipse projects.
• Currently Memcheck, Massif and Cachegrind are supported.
• Valgrind 3.3.0 or greater is required.

Installing

• Add the update site (see: http://www.eclipse.org/linuxtools/downloads.php for details)
• Install Valgrind Integration

Using Memcheck

• Memcheck discovers memory management problems in your program. (http://www.valgrind.org/docs/manual/mc-manual.html)
• It is the default tool.
• The launch shortcut can create a configuration with default options for your program.
  • Same as running valgrind ./myprog from the command line.
  • After a configuration has already been created, the launch shortcut will launch your most recently used configuration.
• Any memory management errors reported by Valgrind are listed in the Valgrind view, which should appear automatically.
  • Each error has a stack trace.
  • If the source can be resolved, double-clicking on the stack frame will open an editor to its line.
• View and modify your profile configuration by selecting "Profile Configurations".
  • All Valgrind related configuration options can be changed from the Valgrind Options tab.
  • General options and Suppressions are Valgrind core options and are not related to the tool being run.
  • Details on Memcheck suppressions can be found here.
  • Specific Memcheck options can also be configured.
