P4 to C compilation fails with syntax error

MarcusWichelmann commented 3 years ago

Hi,

I tried running the examples and got the following error:

root@ddos-test:~/t4p4s# ./t4p4s.sh ./examples/l2fwd-gen.p4 
[COMPILE  P4-16] ./examples/l2fwd-gen.p4 @std
Traceback (most recent call last):

    from hlir16.p4node import P4Node

SyntaxError: invalid syntax

Error: P4 to C compilation failed (error code: 1)

Any idea?

Assignment expressions are a new feature in python 3.8 (https://www.python.org/downloads/release/python-380/). You probably need to upgrade your python version if you want to use any of the hlir16 commits using this new syntax.

Best regards.

Thank you, it works with Python 3.9. 👍🏼
