--- !ruby/object:File {} h1. SDK Build This explains how to build the Replicant SDK. h2. Prerequisites Before building, you must make sure that: * You have installed the build dependencies: [[BuildDependenciesInstallation]] * You have downloaded Replicant 4.2 sources: [[ReplicantSources]] * Your sources are up to date: [[ReplicantSources#DownloadingUpdating-the-source-from-the-repos|Downloading/Updating the source from the repos]] * Your terminal is running in the directory where the sources were downloaded h2. Warning *Do not build as root, always build as user.* h2. Building Setup the build environment: <pre> source build/envsetup.sh lunch sdk-eng export ANDROID_JAVA_HOME=$JAVA_HOME </pre> Start the build: <pre> parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) make -j$parallel_tasks sdk </pre> The -jn argument is to indicate the number of parallel tasks during the build. You can remove it from the command line to have only one task at a time. With fast hardware, best results will come with @-j9@, @-j16@ and @-j32@. h2. Output files The produced files are located at: * built SDK: @out/host/linux-x86/sdk/@ * built host tools: @out/host/linux-x86/bin/@
