The commit d4be264061 ("classes/archiver: run do_unpack_and_patch after
do_preconfigure") correctly moved do_unpack_and_patch to depend on
do_preconfigure, but left do_ar_patched as a dependency of do_configure
introduced from 8a7c779487 ("classes/archiver: Create patched archive
before configuring"). Having do_configure depend on do_ar_patched is
blatantly wrong. Firstly, doing so causes the taskhash of do_configure
to change which is undesirable. Secondly, the anon python that sets up
the tasks carefully skips GCC recipes that depend on gcc-source to
provide their source code since running do_unpack_and_patch in them
would delete the source code. Adding in the dependency effectively
bypasses this and makes these recipes delete the shared gcc-source
This fixes errors (for real this time) like:
cat: .../gcc/defaults.h: No such file or directory
when making certain configuration changes.
For posterity, you could easily reproduce gcc-source being erased by
running the commands (replacing aarch64 with your correct target arch):
bitbake -c cleanall gcc-source gcc-cross-aarch64
bitbake -c do_deploy_archives gcc-source
# The following would fail because
# gcc-cross-aarch64:do_unpack_and_patch erases shared source, so
# do_configure after that fails.
bitbake gcc-cross-aarch64

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.
