| #ignore_warnings - can you ignore 202 and 226? |

The Wiznet library has a number of things that cause compiler warnings. Since we won't fix them, I am ignoring them when the files are included:
| Code: | #ignore_warnings 202,203,204,209,226,237
// Include Wiznet in include path:
#include "Ethernet/wizchip_conf.c" // Include first.
#include "Ethernet/socket.c"
#include "Ethernet/W5500/w5500.c"
//#include "Internet/httpServer/httpServer.c"
#ignore_warnings NONE
|
But, I still get 202 and 226 warnings:
| Quote: | >>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_readdata SCR=22742
>>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_readdata SCR=22742
>>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_writedata SCR=22742
>>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_writedata SCR=22742
>>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_readdata SCR=22742
>>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_readdata SCR=22742
>>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_writedata SCR=22742
>>> Warning 226 "main.c" Line 127(1,1): Function never called wizchip_bus_writedata SCR=22742
>>> Warning 202 "Ethernet\socket.c" Line 218(14,24): Variable never used: local_port

I even tried "#ignore_warnings ALL".
Is there a trick I need to know?

I have never had this issue.
All of my #ignore_warning directives have worked.
Maybe a compiler issue CCS needs to be advised...?

Good to know. I have a support e-mail going with them over my wacky work-around I had to use to keep "non-called" functions in the code so a function pointer to them can work, so I'll mention that as well.

I suspect it is the placement.
This warning is not generated when you #include the file, but when the
compiler gets to the end of the compilation, and 'realises' that the
function is not called. The ignore warnings none line turns the warnings
back on at this point.
Some warnings are immediate. Some are for the whole code/ |
