[meta-xilinx] meta-xilinx-tools shell function parsed as python function

[Monaghan, Michael L. (GSFC-5870)]

Hello all,

Thank you in advance for your time. I’m new to the Yocto Project and OpenEmbedded.

I am trying to add the meta-xilinx-tools layer to a working Yocto/OE build for the zcu102 board, but bitbake subsequently fails to parse meta-xilinx/meta-xilinx-bsp/recipes-bsp/device-tree/device-tree.bb. Here are some snippets from the console.

WARNING: /yocto/projects/yocto-zcu102/build/../meta-xilinx/meta-xilinx-bsp/recipes-bsp/device-tree/device-tree.bb: Error during finalise of /yocto/projects/yocto-zcu102/build/../meta-xilinx/meta-xilinx-bsp/recipes-bsp/device-tree/device-tree.bb
…
ERROR: Unable to parse /yocto/projects/yocto-zcu102/build/../meta-xilinx/meta-xilinx-bsp/recipes-bsp/device-tree/device-tree.bb:20:23

             code = compile(check_indent(str(node)), filename, "exec",
    >                       ast.PyCF_ONLY_AST)

         ^
SyntaxError: invalid syntax


Summary: There were 10 WARNING messages shown.
Summary: There was 1 ERROR message shown, returning a non-zero exit code.

I found the offending function at meta-xilinx-tools/recipes-bsp/device-tree/device-tree.bbappend:71

do_compile_prepend() {
                                [ -e ${DTS_FILES_PATH}/system.dts ] && rm ${DTS_FILES_PATH}/system.dts
}

And it appears to ultimately override this python function at openembedded-core/meta/classes/devicetree.bbclass:119

python devicetree_do_compile() {
  …
}

devicetree.bbappend:do_compile_prepend() is clearly a shell script, but the “SyntaxError: invalid syntax” message indicates that it is being parsed as a python function! It looks like this could be a problem with bitbake or yocto/oe but I thought I would reach out to the community here first. Has anyone here encountered this?

I’m using the rel-v2018.3 branch for meta-xilinx-tools and the thud branch for everything else. I have tried using version 1.40 and the master branch of bitbake.

Thanks,
Michael Monaghan
