I have working system with lwip and freeRTOS on this bord. I would like to add open62541 implementation of OPC UA with single .c and .h files like described here.
I was able to create open62541 .c and .h files and added these files to my working project. But now I can't compile with gcc for ARM. My compiler returns the following partial error message:
../Application/CM7/Src/open62541.c:40310:26: error: 'UA_Server {aka struct UA_Server}' has no member named 'serviceMutex'
