Morning all i've some problem in building forte with open62541 for my project,

Hi,

try to undefine IN in the opcua_handler. Some windows header add the preprocessor symbols IN and OUT, which can clash with FORTE code.

Best regards,
Martin

As we stumbled across the same problem today and after a longer search the problem is not to add undefs for IN and OUT but to remove them. I had to remove the undefs from forte_config.h.in and from funcblock.h. Unfortunately I could not figure out how winsock2.h was included in opcua_handler to better narrow this down. Does anyone know how to get an include hierarchy out of Visual Studio?

opcua handler includes sockhand.h if FORTE_COM_OPC_UA_CUSTOM_HOSTNAME is not defined, so the function "gethostname" can be used. IMHO the IN and OUT problem won't go away easily. A solution will be to restrict including of system headers to the arch folder and maybe to a single file there. This will create a bottle neck but also allow to take of the IN and OUT there. Any file who wants to use a system header, will just include this file.
