I'm including a zip file containing all the updated headers and source files of LWIP for your reference. [..]Here are the details of the issues I'm facing: * *Error #137 in |lwiplib.c| (Path: /NetworkModule/utils)*: o Struct "ip_addr" has no field "addr" at lines 739, 740, 741, 745, 746, 747, 1174, 1198, 1245, 1246, and 1247.
There's no file 'lwiplib.c' in you ZIP, but I guess you are invalidly accessing the member 'addr' of the type 'ip_addr'. Don't do that. Use the accessor functions (you find them in ip.h, I think) to ensure portability accross versions.
* *Error #137 in |.ccsproject| (External Location: C:\ti5\third_party\lwip-1.4.1\src\core)*: o Struct "udp_pcb" has no field "lwip_recv" at line 404 (File: udp.c).
This and the other errors seem to come from the fact that 'recv' gets defined to 'lwip_recv' (and probably same issue for 'poll' below). This is done in sockets.h, but as a macro taking parameters, and sockets.h should not even be included while compiling udp.c and others, so I can't really help you here. Regards, Simon
o Struct "tcp_pcb" has no field "lwip_recv" at lines 501, 541, 1568, and 1581 (File: tcp.c). o Struct "tcp_pcb_listen" has no field "lwip_accept" at lines 956 and 667 (File: tcp_in.c). * *Error #56-D and #29 in |.ccsproject| (External Location: C:\ti5\third_party\lwip-1.4.1\src\core)*: o Too many arguments in invocation of macro "recv" at line 404 (File: udp.c). o Expected an expression at line 1428 (File: tcp.c). o Too few arguments in invocation of macro "poll" at line 1428 (File: tcp.c). I have attempted to troubleshoot these issues by reviewing the documentation and searching for similar problems faced by others, but I haven't found a clear solution yet. Any help or pointers on how to address these errors would be immensely helpful. I am especially interested in understanding if these are known issues when upgrading from LWIP 1.4.1 to 2.2.0, and if there are any specific changes or considerations I should be aware of. Thank you in advance for your time and assistance. Your expertise and advice are invaluable to me and others facing similar challenges. Best, Timothy
