1 Release notes for Valgrind
2 ~~~~~~~~~~~~~~~~~~~~~~~~~~
3 If you are building a binary package of Valgrind for distribution,
4 please read README_PACKAGERS. It contains some important information.
6 If you are developing Valgrind, please read README_DEVELOPERS. It contains
7 some useful information.
9 For instructions on how to build/install, see the end of this file.
11 If you have problems, consult the FAQ to see if there are workarounds.
16 Valgrind is a framework for building dynamic analysis tools. There are
17 Valgrind tools that can automatically detect many memory management
18 and threading bugs, and profile your programs in detail. You can also
19 use Valgrind to build new tools.
21 The Valgrind distribution currently includes seven production-quality
22 tools: a memory error detector, two thread error detectors, a cache
23 and branch-prediction profiler, a call-graph generating cache and
24 branch-prediction profiler, and two heap profilers. It also includes
25 one experimental tool: a SimPoint basic block vector generator.
27 Valgrind is closely tied to details of the CPU, operating system and to
28 a lesser extent, compiler and basic C libraries. This makes it difficult
29 to make it portable. Nonetheless, it is available for the following
49 Note that AMD64 is just another name for x86_64, and Valgrind runs fine
50 on Intel processors. Also note that the core of macOS is called
51 "Darwin" and this name is used sometimes.
53 Valgrind is licensed under the GNU General Public License, version 2.
54 Read the file COPYING in the source distribution for details.
56 However: if you contribute code, you need to make it available as GPL
57 version 2 or later, and not 2-only.
62 A comprehensive user guide is supplied. Point your browser at
63 $PREFIX/share/doc/valgrind/manual.html, where $PREFIX is whatever you
64 specified with --prefix= when building.
67 Building and installing it
68 ~~~~~~~~~~~~~~~~~~~~~~~~~~
69 To install from the GIT repository:
71 0. Clone the code from GIT:
72 git clone https://sourceware.org/git/valgrind.git
73 There are further instructions at
74 http://www.valgrind.org/downloads/repository.html.
76 1. cd into the source directory.
78 2. Run ./autogen.sh to setup the environment (you need the standard
79 autoconf tools to do so).
81 3. Continue with the following instructions...
83 To install from a tar.bz2 distribution:
85 4. Run ./configure, with some options if you wish. The only interesting
86 one is the usual --prefix=/where/you/want/it/installed.
90 6. Run "make install", possibly as root if the destination permissions
93 7. See if it works. Try "valgrind ls -l". Either this works, or it
94 bombs out with some complaint. In that case, please let us know
95 (see http://valgrind.org/support/bug_reports.html).
97 Important! Do not move the valgrind installation into a place
98 different from that specified by --prefix at build time. This will
99 cause things to break in subtle ways, mostly when Valgrind handles
