Description Ross Burton 2015-07-23 20:36:20 UTC 
With 4.1.2 kernel there are two build failures that have repeated (but not always) on the autobuilder.

eg https://autobuilder.yoctoproject.org/main/builders/nightly-world/builds/405/steps/BuildImages/logs/stdio

| make[3]: *** No rule to make target '.../work/qemux86-poky-linux/perf/1.0-r9/perf-1.0/util/parse-events-flex.o', needed by '.../work/qemux86-poky-linux/perf/1.0-r9/perf-1.0/util/libperf-in.o'.  Stop.

(odd)

|   LD       .../work/qemux86-poky-linux/perf/1.0-r9/perf-1.0/perf-in.o
| .../work/qemux86-poky-linux/perf/1.0-r9/perf-1.0/builtin-probe.o: file not recognized: File truncated
| .../work-shared/qemux86/kernel-source/tools/build/Makefile.build:112: recipe for target '.../work/qemux86-poky-linux/perf/1.0-r9/perf-1.0/perf-in.o' failed

(build race?)
Comment 1 Bruce Ashfield 2015-07-24 19:51:57 UTC 
ross: how often is this happening ? Would it be possible to do some runs with parallel make disabled ? I'd like to determine if this is a task race, or a Makefile dependency race.
Comment 2 Ross Burton 2015-07-24 20:26:42 UTC 
Occasionally, I've seen it on the AB twice and a few times locally.  If I can replicate here I'll disable parallel builds.
Comment 3 Ross Burton 2015-07-24 20:32:52 UTC 
Happened again in the world build:
https://autobuilder.yoctoproject.org/main/builders/nightly-world/builds/409/steps/BuildImages/logs/stdio

(I also note that it found lzma in that run)
