Asked by XuXiaodong

Hi,
I use the new version(7.2.1) arm-none-eabi-gcc for my project, but I occur a problem, undefined reference to 'strnicmp' when linking, but I use 4.8.2 version is OK.

Have somebody met the issue same? Can you please provide me with any ideas on solving this issue?

Thanks very much!

Hi,

AFAICS, strnicmp isn't a C99 function. Try using strncasecmp() instead (though that isn't a C99 std string function either, and therefore is open to change).

Thanks,
Tejas.

Hi,

Thanks for your reply!

 Well, using strncasecmp() is OK! I wonder that why 4.8.4 can use the API?
