Re: [lwip-users] Assistance Required: Errors in lwiplib.c and Related Files After Upgrading LWIP from 1.4.1 to 2.2.0

I'm including a zip file containing all the updated headers and source files of LWIP for your reference.

Best,

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):

  • 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):

  • Struct "udp_pcb" has no field "lwip_recv" at line 404 (File: udp.c).
  • Struct "tcp_pcb" has no field "lwip_recv" at lines 501, 541, 1568, and 1581 (File: tcp.c).
  • 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):

  • Too many arguments in invocation of macro "recv" at line 404 (File: udp.c).
  • Expected an _expression_ at line 1428 (File: tcp.c).
  • 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
