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