Before you can start working on your first simulator, there are a few things
you need to do.
Install Bazel
MPACT-Sim uses the Bazel build system version 6.1.1,
so in order to work through the tutorials, you need to install Bazel. The
easiest way to install and manage bazel is to install
Bazelisk, which is a wrapper for
Bazel written in Go. Installation instructions are provided at its
github site.
Install Git
The MPACT-Sim infrastructure and tutorials is hosted on github.com, so a working
installation of git is required. Any reasonable version
of git should work, so choose the one that is suitable for your system.
If you don't already have git, and you are on linux, you you can usually
install git from the command line as follows:
$ sudo apt-get update
$ sudo apt-get install git
On other systems you can download an installer from git
downloads.
Download MPACT-Sim tutorials repository
All the code needed for these tutorials are contained in the github
mpact-sim-codelabs repository.
Clone this repository using the command: git clone
https://github.com/google/mpact-sim-codelabs.
To verify that all is working properly, change to the mpact-sim-codelabs
directory and type in the command bazel build ...:all. This will download all
required dependencies and build every target. The first time around this will
take a few minutes, but the results are cached, and subsequent builds will
finish much more quickly. The command will print out progress, including
DEBUG messages and a couple of compiler warnings. The last part of the output
should look similar to:
INFO: Elapsed time: 308.268s, Critical Path: 279.57s
INFO: 991 processes: 314 internal, 677 linux-sandbox.
INFO: Build completed successfully, 991 total actions
