 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/@
