It failed as below when rerun do_install for tcl: $ bitbake tcl $ bitbake tcl -f -cinstall [snip] | NOTE: make -j 72 DESTDIR=/build/tmp/work/core2-64-wrs-linux/tcl/8.6.10-r0/image install | abort()ing pseudo client by server request. See https://wiki.yoctoproject.org/wiki/Pseudo_Abort for more details on this. | /build/tmp/work/core2-64-wrs-linux/tcl/8.6.10-r0/temp/run.do_install.3490694: line 184: 3499214 Aborted (core dumped) make -j 72 "$@" By default the S is ${WORKDIR}/${BPN}-${PV}, but after unpack, the tcl source [1] unpacked to ${WORKDIR}/${BPN}${PV} and all the files under ${WORKDIR}/${BPN}${PV} are acutally the source files. But the the main Makefile.in is under ${WORKDIR}/${BPN}${PV}/unix for tcl, so there is below logic in tcl recipe: S = "${WORKDIR}/${BPN}${PV}/unix" To adapt the potential pseudo changes, there is a general logic to exclude ${S} from pseudo database in base.bbclass in [2]. That's to say, just the dir ${WORKDIR}/${BPN}${PV}/unix is excluded from the pseudo database. But it's not enough for tcl, we need to exclude the actual source dir ${WORKDIR}/${BPN}${PV} from pseudo database specifically to fix the above do_install failure.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
