bitbake failed

ninja: build stopped: subcommand failed

Cause

It usually happens on low performance host machine, and almost the qt* or clang* are the failed ones.

Solution

• build the failed one individually

(It is recommended to use this way first.)

e.g.

$ bitbake -k clang

or

$ bitbake -k qtwebkit

• decrease number of threads used for the parallel build.

(The less number of threads will take more time to finish the whole building process.)

get original nummber of threads

$ grep "BB_NUMBER_THREADS" conf/local.conf | sed "s/.*\"\(.*\)\"$/\1/"

set new number of threads

$ sed -i "s/BB_NUMBER_THREADS.*/BB_NUMBER_THREADS = \"${THREADS}\"/" conf/local.conf

(remember to replace the ${THREADS} with the appropriate one)

make error

Solution

• clean the failed one, then re-build it individually

$ bitbake -k ${failed_package} -c clean

$ bitbake -k ${failed_package}
