| 19 | 5 | Paul Kocialkowski | Setup the build environment: |
| 20 | 1 | Matt Kraai | <pre> |
| 21 | 5 | Paul Kocialkowski | source build/envsetup.sh |
| 22 | 8 | Paul Kocialkowski | lunch replicant_crespo-userdebug |
| 23 | 5 | Paul Kocialkowski | export ANDROID_JAVA_HOME=$JAVA_HOME |
| 24 | 1 | Matt Kraai | </pre> |
| 25 | 5 | Paul Kocialkowski | |
| 26 | 1 | Matt Kraai | Start the build: |
| 27 | 7 | Paul Kocialkowski | <pre> |
| 28 | parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) |
||
| 29 | 8 | Paul Kocialkowski | make -j$parallel_tasks bacon |
| 30 | 1 | Matt Kraai | </pre> |
| 31 | 4 | Paul Kocialkowski | |
| 32 | 5 | Paul Kocialkowski | 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@. |
