Release notes for Valgrind

~~~~~~~~~~~~~~~~~~~~~~~~~~

If you are building a binary package of Valgrind for distribution,

please read README_PACKAGERS.  It contains some important information.



If you are developing Valgrind, please read README_DEVELOPERS.  It contains

some useful information.



For instructions on how to build/install, see the end of this file.



If you have problems, consult the FAQ to see if there are workarounds.



Executive Summary

~~~~~~~~~~~~~~~~~

Valgrind is a framework for building dynamic analysis tools. There are

Valgrind tools that can automatically detect many memory management

and threading bugs, and profile your programs in detail. You can also

use Valgrind to build new tools.



The Valgrind distribution currently includes seven production-quality

tools: a memory error detector, two thread error detectors, a cache

and branch-prediction profiler, a call-graph generating cache and

branch-prediction profiler, and two heap profilers. It also includes

one experimental tool: a SimPoint basic block vector generator.



Valgrind is closely tied to details of the CPU, operating system and to

a lesser extent, compiler and basic C libraries. This makes it difficult

to make it portable.  Nonetheless, it is available for the following

platforms: 



- X86/Linux

- AMD64/Linux

- PPC32/Linux

- PPC64/Linux

- ARM/Linux

- ARM64/Linux

- X86/macOS

- AMD64/macOS

- S390X/Linux

- MIPS32/Linux

- MIPS64/Linux

- nanoMIPS/Linux

- X86/Solaris

- AMD64/Solaris

- X86/FreeBSD

- AMD64/FreeBSD

- ARM64/FreeBSD



Note that AMD64 is just another name for x86_64, and Valgrind runs fine

on Intel processors.  Also note that the core of macOS is called

"Darwin" and this name is used sometimes.



Valgrind is licensed under the GNU General Public License, version 2. 

Read the file COPYING in the source distribution for details.



However: if you contribute code, you need to make it available as GPL

version 2 or later, and not 2-only.



Documentation

~~~~~~~~~~~~~

A comprehensive user guide is supplied.  Point your browser at

$PREFIX/share/doc/valgrind/manual.html, where $PREFIX is whatever you

specified with --prefix= when building.



Building and installing it

~~~~~~~~~~~~~~~~~~~~~~~~~~

To install from the GIT repository:



  0. Clone the code from GIT:

     git clone https://sourceware.org/git/valgrind.git

     There are further instructions at

     http://www.valgrind.org/downloads/repository.html.



  1. cd into the source directory.



  2. Run ./autogen.sh to setup the environment (you need the standard

     autoconf tools to do so).



  3. Continue with the following instructions...



To install from a tar.bz2 distribution:



  4. Run ./configure, with some options if you wish.  The only interesting

     one is the usual --prefix=/where/you/want/it/installed.



  5. Run "make".



  6. Run "make install", possibly as root if the destination permissions

     require that.



  7. See if it works.  Try "valgrind ls -l".  Either this works, or it

     bombs out with some complaint.  In that case, please let us know

     (see http://valgrind.org/support/bug_reports.html).



Important!  Do not move the valgrind installation into a place

different from that specified by --prefix at build time.  This will

cause things to break in subtle ways, mostly when Valgrind handles

fork/exec calls.
