Hi everyone,

since I've spent many many days on this I wanted to let you know so you don't have to.

 

Short version:

"make -j24 otapackage" cause random build errors

 

Longer version:

The otapackage generation for Lollipop (might also be applicable for M?) will start multiple "make" processes to build an otapackage for each dtb-file (device tree blob). Since there is no dependency on the "otapackage" target, running with the make jobserver enabled (i.e. make -j) this will start multiple builds at the same time causing random build errors (corrupt zip/apk-files etc...).

 

A simple solution to this is to add a dependency on the built files for otapackage.

Example:

 

In build/core/Makefile:1690

 

.PHONY: otapackage

-otapackage:

+otapackage: $(BUILT_TARGET_FILES_PACKAGE) $(DISTTOOLS)
