| 6 | 1 | Denis 'GNUtoo' Carikli | |
| 7 | 9 | Paul Kocialkowski | Before building, you must make sure that: |
| 8 | * You have installed the build dependencies: [[BuildDependenciesInstallation]] |
||
| 9 | * You have downloaded Replicant 4.2 sources: [[ReplicantSources]] |
||
| 10 | * Your sources are up to date: [[ReplicantSources#DownloadingUpdating-the-source-from-the-repos|Downloading/Updating the source from the repos]] |
||
| 11 | * Your terminal is running in the directory where the sources were downloaded |
||

| 13 | h2. Warning |
||
| 14 | |||
| 15 | *Do not build as root, always build as user.* |
||
| 16 | |||
| 17 | h2. Building |
||
| 18 | |||
| 19 | Setup the build environment: |
||
| 20 | 1 | Denis 'GNUtoo' Carikli | <pre> |
| 21 | source build/envsetup.sh |
||
| 22 | 8 | Paul Kocialkowski | lunch sdk-eng |
| 23 | 1 | Denis 'GNUtoo' Carikli | export ANDROID_JAVA_HOME=$JAVA_HOME |
| 24 | </pre> |
||
| 25 | 7 | Paul Kocialkowski | |
| 26 | Start the build: |
||
| 27 | <pre> |
||
| 28 | parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) |
||
| 29 | make -j$parallel_tasks sdk |
||
| 30 | </pre> |
||
| 31 | |||
| 32 | The -jn argument is to indicate the number of parallel tasks during the build. |
||
| 33 | 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@. |
