Error Compiling P4Runtime with T4P4S

Hi, I am trying to compile P4Runtime with T4P4S by following the instructions in README.md file. But I am getting this error,

Error during the compilation of ? to ./build/last/srcgen/controlplane.c

Error: P4 to C compilation failed (error code: 3)

Does anyone have any idea how to resolve it?

Thank you.

Hi!

I believe you don't have all of the dependencies. Did you run bootstrap-t4p4s.sh? That script should have initialized everything. If not, try running the bootstrap first. Some of those dependencies were added as submodules to the git, if the bootstrap doesn't work try running git submodule update --init --recursive, build the dependencies, and try again. If for any reason it does not work, try to clone the hlir16 repository manually from here: https://github.com/P4ELTE/hlir16

Thank you for the response. I ran bootstrap-t4p4s.sh again and it ran perfectly fine. I also manually cloned hlir16 repo again but getting the same error. t4p4s compiles p4-14 programs perfectly, also in t4p4s source code, controlplane.c.py uses hlir variable instead of hlir16 but controlplane.c.py in P4Runtime_GRCPP uses hlir16 instead of hlir). I think there is a problem in setting some environment variables (i.e, hlir or hlir16). Could it be one of the reasons?
