| 10To build gem5, you will need the following software: g++ or clang,
11Python (gem5 links in the Python interpreter), SCons, SWIG, zlib, m4,
12and lastly protobuf if you want trace capture and playback
13support. Please see http://www.gem5.org/Dependencies for more details
14concerning the minimum versions of the aforementioned tools.

18External tools and required versions
| 16Once you have all dependencies resolved, type 'scons
17build/<ARCH>/gem5.opt' where ARCH is one of ALPHA, ARM, NULL, MIPS,
18POWER, SPARC, or X86. This will build an optimized version of the gem5
19binary (gem5.opt) for the the specified architecture. See
20http://www.gem5.org/Build_System for more details and options.

20To build gem5, you will need the following software:
21g++ version 4.3 or newer.
22Python, version 2.4 - 2.7 (we don't support Python 3.X). gem5 links in the
23 Python interpreter, so you need the Python header files and shared
24 library (e.g., /usr/lib/libpython2.4.so) in addition to the interpreter
25 executable. These may or may not be installed by default. For example,
26 on Debian/Ubuntu, you need the "python-dev" package in addition to the
27 "python" package. If you need a newer or different Python installation
28 but can't or don't want to upgrade the default Python on your system,
29 see http://www.gem5.org/Using_a_non-default_Python_installation
30SCons, version 0.98.1 or newer. SCons is a powerful replacement for make.
31 If you don't have administrator privileges on your machine, you can use the
32 "scons-local" package to install scons in your m5 directory, or install SCons
33 in your home directory using the '--prefix=' option.
34SWIG, version 1.3.34 or newer
35zlib, any recent version. For Debian/Ubuntu, you will need the "zlib-dev" or
36 "zlib1g-dev" package to get the zlib.h header file as well as the library
37 itself.
38m4, the macro processor.

414. In this directory, type 'scons build/<ARCH>/gem5.opt' where ARCH is one
42of ALPHA, ARM, MIPS, POWER, SPARC, or X86. This will build an optimized version
43of the gem5 binary (gem5.opt) for the the specified architecture.
