In the beginning it says Traceback (most recent call last): File "/workdir/poky/bitbake/lib/bb/siggen.py", line 150, in SignatureGeneratorOEEquivHash._build_data(fn='/workdir/layers/myrecipe.bb', d=<bb.data_smart.DataSmart object at 0x7fd122baf6a0>): ignore_mismatch = ((d.getVar("BB_HASH_IGNORE_MISMATCH") or '') == '1') > tasklist, gendeps, lookupcache = bb.data.generate_dependencies(d, self.basewhitelist) Then there is the env; at the end there is: parser = bb.codeparser.ShellParser(key, logger) > parser.parse_shell(parsedvar.value) deps = deps | shelldeps File "/workdir/poky/bitbake/lib/bb/codeparser.py", line 343, in ShellParser.parse_shell(value=None): > self._parse_shell(value) self.execs = set(cmd for cmd in self.allexecs if cmd not in self.funcdefs) File "/workdir/poky/bitbake/lib/bb/codeparser.py", line 354, in ShellParser._parse_shell(value=None): except Exception: > bb.error('Error during parse shell code, the last 5 lines are:\n%s' % '\n'.join(value.split('\n')[-5:])) raise AttributeError: 'NoneType' object has no attribute 'split' I've no idea is this is an issue in bitbake or in the documentation or in poky (btw this is on dunfell) 90939 1 ross.burton 2021-07-15 14:49:50 +0000 The problem is that you're using overrides, so what you're entering into the recipe isn't what actually gets evaluated. do_install_prepend_jetson-nano-emmc means "prepend this body to do_install if jeson-nano-emmc is in OVERRIDES". At no point is there a shell function called do_install_prepend_jetson-nano-emmc. Also, - isn't valid in shell functions so even if it was exposed in shell, it wouldn't have that name. If you want to refactor your recipe to have common fragments then write explicit shell functions for those: install_interfaces() { install -d ${D}/etc install -d ${D}/etc/network install -m 0640 ${WORKDIR}/interfaces_nano ${D}/etc/network/interfaces } do_install_prepend_jetson-nano-emmc() { install_interfaces } do_install_prepend_jetson-nano-devkit-emmc() { install_interfaces }
