I am trying to build a server using open62541 by referring to the documentation provided at this page.
I am able to generate the open62541.c and open62541.h files by referring to this webpage. I generated these files using CMake and VisualStudio as described. When I try to compile the myServer.c file, I am getting the following errors.
Most of thr errors describe that certain variable is not defined.I found that UA_SOCKET is not defined in open62541.h or open62541.c files,but in the documentation it is written that these two files are sufficient to build the server file.
Is anyone successful in compiling the server file?Thanks.
