Now it fails like this: 1st term: bitbake -k core-image-core Now when I try to execute another bitbake process 2nd term: bitbake -c fetch -b /OE/shr-core/meta-openembedded/meta-oe/recipes-devtools/klibc/klibc_1.5.25.bb then image build on 1st terminal fails like this: NOTE: Running task 4609 of 5278 (ID: 4347, /OE/shr-core/openembedded-core/meta/recipes-devtools/gcc/gcc_4.6.bb, do_compile) NOTE: package gcc-4.6.1+svnr175454-r12: task do_compile: Started ERROR: Execution of event handler 'run_buildstats' failed Traceback (most recent call last): File "run_buildstats(e)", line 86, in run_buildstats(e=<bb.build.TaskSucceeded object at 0xbcd1f10>) File "buildstats.bbclass", line 5, in write_task_data(status='passed', logfile='/OE/shr-core/tmp/buildstats/klibc-spitz/201109090954/gcc-runtime-4.6.1+svnr175454-r12/do_package', dev='md4', e=<bb.build.TaskSucceeded object at 0xbcd1f10>) IOError: [Errno 2] No such file or directory: '/OE/shr-core/tmp/buildstats/klibc-spitz/201109090954/gcc-runtime-4.6.1+svnr175454-r12/do_package' Or some other weird error. If you cannot run multiple bitbake processes by design then it would be great if 2nd bitbake checks that another bitbake process is already executed and fails to start. I haven't tried it with different users, but if it fails also with different users then it would make bitbake hard to use on some multiuser build machine. 16121 1 richard.purdie 2011-09-09 06:25:01 +0000 You shouldn't be running more than one copy of bitbake within a given build directory. We need to add some locking to prevent that. 17175 2 richard.purdie 2011-11-10 04:22:32 +0000 Fixed in master with http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=eda0ed901532ceb55bcf24bbde2c40a0d8759b69
