Problems Building ua_pubsub_ethernet.c

[Pascal]

Hi, I have problems building ua_pubsub_ethernet.c using make. I have entered the folder of libbpf in ccmake (which is required), but when building the open62541 project I get the following error:

In file included from .../open62541/plugins/ua_pubsub_ethernet.c:54:

Hi, Pascal. I encountered with the same error, did you solve it? If so, how did you solve it?

Best regards,
