Hi,
remember when the Jenkins was failing on random targets and the log always contained this message, where it stated it can't compile some object file due to missing dependency, whose path was "trimmed" ?
See this log from my machine:
marex@bfu:~/U-Boot/u-boot-imx$ bash ../compile/compile-xfi3.sh >/dev/null make[2]: *** No rule to make target `/home/mar', needed by `/home/marex/U- Boot/u-boot-imx/spl/arch/arm/cpu/arm926ejs/mxs/spl_power_init.o'. Stop. make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/home/marex/U-Boot/u-boot- imx/spl/arch/arm/cpu/arm926ejs/mxs/libmxs.o] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [spl/u-boot-spl.bin] Error 2 make: *** Waiting for unfinished jobs....
marex@bfu:~/U-Boot/u-boot-imx$ bash ../compile/compile-xfi3.sh >/dev/null
marex@bfu:~/U-Boot/u-boot-imx$ cat ../compile/compile-xfi3.sh export PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/mnt/work/elftosb-10.12.01/bld/linux/ make CROSS_COMPILE=arm-linux-gnueabi- clean mrproper make CROSS_COMPILE=arm-linux-gnueabi- xfi3_config make CROSS_COMPILE=arm-linux-gnueabi- -j9 u-boot.sb marex@bfu:~/U-Boot/u-boot-imx$ pwd /home/marex/U-Boot/u-boot-imx
So, I am compiling in /home/marex/U-Boot/u-boot-imx (in-tree build) using the above commands. First run failed, any subsequent run did not. And the first run failed because it was missing this "/home/mar" dependency. It's exactly the same as when Jenkins failed at these random targets.
I cannot reliably reproduce this bug, but it seems to be quite a slimy one. The grease is dripping down it's body.
Any ideas?
Thanks!
btw. tool versions:
