Compile demo p4 #1

Closed Dscano closed 4 years ago

Dscano commented 4 years ago

Hi,

I download and install P4-OvS succesfully, then I try to run the demo https://github.com/osinstom/P4-OvS/blob/p4/Documentation/topics/p4/getting-started.md and when I try to compile the demo-2.p4 and demo.p4 I get this error.

p4c-ubpf --arch ubpf -o demo.c --p4runtime-files demo.p4info.txt demo-2.p4
demo-2.p4(41):syntax error, unexpected IDENTIFIER "standard_metadata"
parser prs(packet_in packet, out Headers_t hdr, inout metadata meta, inout standard_metadata
                                                                           ^^^^^^^^^^^^^^^^^

Hi!

Please, make sure you have the latest version of p4c installed on your environment. The error above indicates that the architecture model used for compilation is an old one. I suggest you to re-install p4c.

Note that the current architecture model is located under /usr/local/share/p4c/p4include/ubpf_model.p4. Make sure there is the newest version there.

Hi osinstom,

My "p4 tools" are installed on ubunthu 16.04. I have reinstall p4c last friday, I checked the various folders, e.g, p4include,backend,include etc and the ubpf files are present. I'll try to reinstall all the environment Thank you.
