Error:cast from ' char* ' to ' int ' loses precision

An error occurred at compile time:

Error:cast from ' char* ' to ' int ' loses precision

Cause: The program exists

char * addrCom;
addrCom = ...... // assignment
if (-1 == (int) addrCom) // cause compilation error
{......} 


The above is an implicit conversion, which changes to the standard C + + display type conversion:static_cast<int> or this is reinterpret_cast<int>

is still:

Error:cast from ' char* ' to ' int ' loses precision

Finally Google a bit, found the answer: http://stackoverflow.com/questions/1640423/error-cast-from-void-to-int-loses-precision

You should change (int) addrcom to (long) addrcom

explanation :

Because my compiled system is linux64 bit, its pointer type and long size are equal (8B) and int type 4B, it will appear: loses precision.

Therefore: The Char*-->long is first, then automatically converted from long to int.
