problem in string.h lib in codevision

[tariq]

hi
I'm using codevision AVR. in string.h lib when one of the arrays is const an error occurs.

for example i want to put a array of string from one array to another like this :

unsigned char A[11];
const unsigned char B[11]={"HELLOWORLD"};

when i use strncpy like this:

strncpy(A,B,10);

i have this error

Error:, #included from: main.c: function argument #2 of type 'flash unsigned char [11]' is incompatible with required parameter of type 'unsigned char *'

and this is the same for all of string.h lib functions.

in ARM and keil compiler i didn't had this problem but in codevision error occurs.

i know i can use for loop but is there any way to avoid this error?

When you made the constant, it will be placed in ROM (flash). The library seems not to be able to copy from flash to RAM.
I do not know what you are trying to do, to help with a workaround for it.
