A previous commit updated the minimum required version of scons to 3.0 The gcn Dockerfile previously installed scons from apt, which installed scons 2.4, as the Dockerfile is based on Ubuntu 16 This patch installs scons through pip, which installs scons 3.1 Change-Id: I4f731b301f97e25c730df26afde20ae1cdfaa1b3 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/34075 Reviewed-by: Matt Sinclair <mattdsinclair@gmail.com> Reviewed-by: Daniel Gerzhoy <daniel.gerzhoy@gmail.com> Reviewed-by: Jason Lowe-Power <power.jg@gmail.com> Reviewed-by: Matthew Poremba <matthew.poremba@amd.com> Maintainer: Matt Sinclair <mattdsinclair@gmail.com> Maintainer: Jason Lowe-Power <power.jg@gmail.com> Tested-by: kokoro <noreply+kokoro@google.com>
This is the gem5 simulator. The main website can be found at http://www.gem5.org A good starting point is http://www.gem5.org/about, and for more information about building the simulator and getting started please see http://www.gem5.org/documentation and http://www.gem5.org/documentation/learning_gem5/introduction. To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, SWIG, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/documentation/general_docs/building for more details concerning the minimum versions of the aforementioned tools. Once you have all dependencies resolved, type 'scons build/<ARCH>/gem5.opt' where ARCH is one of ARM, NULL, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. See http://www.gem5.org/documentation/general_docs/building for more details and options. The basic source release includes these subdirectories: - 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. If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
