    When I do a "echo $CC" I get this:- arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/opt/mybuild_project/sysroots/cortexa9hf-neon-poky-linux-gnueabi

    @ethanhs
    can you do which arm-poky-linux-gnueabi-gcc?
    asif
    @getasif
    Sure one moment please, I will let you know the absolute path for that
    /opt/mybuild_project/sysroots/x86_64-personal-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc
    Ethan Smith
    @ethanhs
    perhaps you need to set CC to use the absolute path?

    I have tried that as well
    But let me try that again.
    I executed this and its the same failure message:
    sudo python3 setup.py --verbose build --compiler=/opt/mybuild_project/sysroots/x86_64-personal-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc

    Hello @ethanhs here is one update. I assigned the os.environ["CC"] and os.environ["CXX"] to the absolute path based compilers respectively in setup.py and executed this command: sudo python3 setup.py --verbose build

    Sorry, it looks like your Python install is incomplete
    asif
    @getasif
    I just upgraded my python, so now upon doing a "python3 --version" I get this: Python 3.6.8
    Ethan Smith
    @ethanhs
    Your system Python won't work if you are cross compiling
    I'm afraid I don't have all of the knowledge or time to help more
    asif
    @getasif
    Where as when I source the file for setting up the cross-compilation for ARM, I get this version of python3: Python 3.5.2

    hi -- question
    I want to parse py2 code with type annotations: https://pastebin.com/2KKdrPSg
    but when running this, the parser is complaining about a syntax error in the code, due to type annotations
    but isn't typed_ast suppose to support...types?
    https://github.com/python/typed_ast/blob/master/ast27/Parser/Python.asdl#L13 the syntax tree for ast27 seems to agree with me here
    Ethan Smith
    @ethanhs
    @cripplet Type annotations are only supported in Python 3
    Type comments are parsed by typed ast in Python 2
    see https://www.python.org/dev/peps/pep-0484/#type-comments
    Minke Zhang
    @cripplet
    But this isn't the case -- when attempted to parse the "src" variable in the pastebin file, typed_ast.ast27 throws a RuntimeError, complaining about the syntax of "src"
    oh I see
    @ethanhs thanks, that clears it up :(
