Hi all, I'm trying to automate longterm stable compilation for validation needs, but facing issue with mutli-threaded compilation of 4.14.122 (and other version). Reproduction procedure: wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.9.122.tar.gz tar xvf linux-4.9.122.tar.gz cd linux-4.9.122 make mrproper wget https://raw.githubusercontent.com/pcengines/apu2-documentation/master/configs/config-4.14.59 -O .config make olddefconfig make -j$(nproc) deb-pkg bzImage echo $? I'm getting 2 despite all components built correctly. When I do not define jobs: make deb-pkg bzImage Return code is 0. I have this effect not only for my custom config - looks like x86_64_defconfig also have similar problem. In failing case (for my config) in logs I see something like: (...) ld: cannot find arch/x86/kernel/cpu/mshyperv.o: No such file or directory make[3]: *** [scripts/Makefile.build:449: arch/x86/kernel/cpu/built-in.o] Error 1 make[2]: *** [scripts/Makefile.build:547: arch/x86/kernel/cpu] Error 2 LD drivers/xen/built-in.o make[1]: *** [scripts/Makefile.build:547: arch/x86/kernel] Error 2 make: *** [Makefile:1008: arch/x86] Error 2 make: *** Waiting for unfinished jobs.... ld: cannot find drivers/xen/cpu_hotplug.o: No such file or directory ld: cannot find drivers/xen/fallback.o: No such file or directory ld: cannot find drivers/xen/grant-table.o: No such file or directory ld: cannot find drivers/xen/features.o: No such file or directory ld: cannot find drivers/xen/balloon.o: No such file or directory ld: cannot find drivers/xen/manage.o: No such file or directory ld: cannot find drivers/xen/preempt.o: No such file or directory ld: cannot find drivers/xen/time.o: No such file or directory make[2]: *** [scripts/Makefile.build:449: drivers/xen/built-in.o] Error 1 make[1]: *** [scripts/Makefile.build:547: drivers/xen] Error 2 make: *** [Makefile:1008: drivers] Error 2 make KBUILD_SRC= So it looks like build system tries to link objects which are not built yet. What would be best way to fix that behavior? Make version: GNU Make 4.2.1 Built for x86_64-pc-linux-gnu gcc: gcc (Debian 8.2.0-7) 8.2.0 ld: GNU ld (GNU Binutils for Debian) 2.31.1 Full log with errors for make defconfig: https://pastebin.com/hMadtLeU Full log with errors for my custom config: https://pastebin.com/Kmbjm0qJ Best Regards, -- Piotr Król Embedded Systems Consultant https://3mdeb.com | @3mdeb_com
