This is the gem5 simulator. For detailed information about building the simulator and getting started please refer to: * The main website: http://www.gem5.org * Documentation wiki: http://www.gem5.org/Documentation * Doxygen generated: http://www.gem5.org/docs * Tutorials: http://www.gem5.org/Tutorials Specific pages of interest are: http://www.gem5.org/Introduction http://www.gem5.org/Build_System http://www.gem5.org/Dependencies http://www.gem5.org/Running_gem5 Short version: External tools and required versions To build gem5, you will need the following software: g++ version 4.3 or newer. Python, version 2.4 - 2.7 (we don't support Python 3.X). gem5 links in the Python interpreter, so you need the Python header files and shared library (e.g., /usr/lib/libpython2.4.so) in addition to the interpreter executable. These may or may not be installed by default. For example, on Debian/Ubuntu, you need the "python-dev" package in addition to the "python" package. If you need a newer or different Python installation but can't or don't want to upgrade the default Python on your system, see http://www.gem5.org/Using_a_non-default_Python_installation SCons, version 0.98.1 or newer. SCons is a powerful replacement for make. If you don't have administrator privileges on your machine, you can use the "scons-local" package to install scons in your m5 directory, or install SCons in your home directory using the '--prefix=' option. SWIG, version 1.3.34 or newer zlib, any recent version. For Debian/Ubuntu, you will need the "zlib-dev" or "zlib1g-dev" package to get the zlib.h header file as well as the library itself. m4, the macro processor. 4. In this directory, type 'scons build/<ARCH>/gem5.opt' where ARCH is one of ALPHA, ARM, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. If you have questions, please send mail to firstname.lastname@example.org WHAT'S INCLUDED (AND NOT) ------------------------- The basic source release includes these subdirectories: - gem5: - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - src: source code of the gem5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images.
