How do I compile a 64-bit program on SPARC??

Hi,

wcslen(), strlen() returns size_t.
On 64-bit platform i want to use int like

str length is 10.

int len = wcslen(str);


On 64-bit what should I need to do if i wants the length in int. Because getting error as "Conversion of 64 bit type value to "int" causes truncation".
if i will use size_t instead of int like
size_t len = wcslen(str);

Then it is feasible. Should I do casting like:

int len = (int) wcslen(str);

which is better to use?
