linker message: ERROR L127: UNRESOLVED EXTERNAL SYMBOL SYMBOL :?C?CSTOPTR MODULE : C:\KEIL\C51\LIB\C51BL.LIB (STRNCPY) this error is present if I only assign a value char to a variable char and a variable far is declared. x.e. f='\0' classic 8051 micro Ver C51 6.20 & 6.23 LIB 4.20 far support enabled
no I have not included XBANKING.A51 in my project, because I have configured xfar variables only with file : L51_bank.a51... with P1.4,P1.5 & P1.6 port pin. so the assembler STOPTR is no present in XBANKING.A51. /*******************/ if I not declare a far variable or I not use sprintf function the error is not present. thanks Francesco
Are you using LX51 Linker? Jon
yes I'm using LX51 linker..... but i think hat the error is located in libraries extended for far variables.... i'm rewriting function for string manipulation .... Francesco
