所编写的程序出现很多警告如: uncalled segment,ignored for overlay process segment: ?pr?ch375filewrite? segment: ?pr?xdelay100us? segment: ?pr?xfileenameenumer? segment: ?pr?_xwritetoextbuf?等 unresolved external symbol symbol: ch375filereadx symbol: ch375diskconnect symbol: ch375filewritex symbol: ch375libconfig等
reference made to unresolved external symbol:ch375intstatus symbol: ch375init等
请问一下,出现这些警告是什么原因?
