What branch is this ?

[RaghavPrabhakar66]

Master, premium both. I have faced this issue since April. I have tried changing gcc version. I have even tried adding initializer_list header files manually but still no luck.

What you need is sudo apt install libstdc++-12-dev

[RaghavPrabhakar66]

To run flowpilot on ubuntu 22.04+, #include <iterator> should be added to opendbc/can/dbc.cc. We should probably update opendbc to latest commit. Closing this issue for now.
