Building Setup the build environment: <pre> source build/envsetup.sh lunch replicant_crespo-userdebug replicant_crespo-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 bacon bootimage make -j$parallel_tasks recoveryimage make -j$parallel_tasks systemimage make -j$parallel_tasks userdataimage </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.
