2 Release notes for Valgrind
3 ~~~~~~~~~~~~~~~~~~~~~~~~~~
4 If you are building a binary package of Valgrind for distribution,
5 please read README_PACKAGERS. It contains some important information.
7 If you are developing Valgrind, please read README_DEVELOPERS. It contains
8 some useful information.
10 For instructions on how to build/install, see the end of this file.
12 If you have problems, consult the FAQ to see if there are workarounds.
17 Valgrind is a framework for building dynamic analysis tools. There are
18 Valgrind tools that can automatically detect many memory management
19 and threading bugs, and profile your programs in detail. You can also
20 use Valgrind to build new tools.
22 The Valgrind distribution currently includes six production-quality
23 tools: a memory error detector, two thread error detectors, a cache
24 and branch-prediction profiler, a call-graph generating cache abd
25 branch-prediction profiler, and a heap profiler. It also includes
26 three experimental tools: a heap/stack/global array overrun detector,
27 a different kind of heap profiler, and a SimPoint basic block vector
30 Valgrind is closely tied to details of the CPU, operating system and to
31 a lesser extent, compiler and basic C libraries. This makes it difficult
32 to make it portable. Nonetheless, it is available for the following
46 Note that AMD64 is just another name for x86_64, and Valgrind runs fine
47 on Intel processors. Also note that the core of MacOSX is called
48 "Darwin" and this name is used sometimes.
50 Valgrind is licensed under the GNU General Public License, version 2.
51 Read the file COPYING in the source distribution for details.
53 However: if you contribute code, you need to make it available as GPL
54 version 2 or later, and not 2-only.
59 A comprehensive user guide is supplied. Point your browser at
60 $PREFIX/share/doc/valgrind/manual.html, where $PREFIX is whatever you
61 specified with --prefix= when building.
64 Building and installing it
65 ~~~~~~~~~~~~~~~~~~~~~~~~~~
66 To install from the Subversion repository :
68 0. Check out the code from SVN, following the instructions at
69 http://www.valgrind.org/downloads/repository.html.
71 1. cd into the source directory.
73 2. Run ./autogen.sh to setup the environment (you need the standard
74 autoconf tools to do so).
76 3. Continue with the following instructions...
78 To install from a tar.bz2 distribution:
80 4. Run ./configure, with some options if you wish. The only interesting
81 one is the usual --prefix=/where/you/want/it/installed.
85 6. Run "make install", possibly as root if the destination permissions
88 7. See if it works. Try "valgrind ls -l". Either this works, or it
89 bombs out with some complaint. In that case, please let us know
90 (see www.valgrind.org).
92 Important! Do not move the valgrind installation into a place
93 different from that specified by --prefix at build time. This will
94 cause things to break in subtle ways, mostly when Valgrind handles
