I'll start with the obvious question - when you say you updated the
headers, do you mean you updated ONLY the headers or did you also
update all of the library files as well?

Dear LWIP Community,
I am Timothy, currently working on a project involving LWIP. I
recently updated the LWIP headers from version 1.4.1 to 2.2.0 and have
encountered multiple errors that I'm struggling to resolve. These
errors are primarily in |lwiplib.c| and related files, and I would
greatly appreciate any guidance or advice you can provide.
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.
*
*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).
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
