assignment makes integer from pointer without a cast

[Chandhru]

Hi,

I am trying to compile my client code developed in C language. i am retrieving argv values for my server address and port name, but i get the following error."assignment makes integer from pointer without a cast".
my compiler is Solaris.

why do i get this error. please help

for example , the following lines returns the error

hostname = *argv[1];
data ="PING";
port =atoi(argv[2]);

It would really help if you provided declarations for postname, data and port. However, assuming that argv is the 2nd argument to main(), it should be:

char *hostname;
int port;
char *data;

hostname = argv[1]; /* this is probably where you're getting the error */
data = "PING";
port = atoi(argv[2]);

i think u need to do a string copy instead of simple
assignment

strcpy(hostname,argv[1]);

other assignments are quite valid and must not cause any error unless the declarations are correct!

Which is the worst thing you can do if hostname is presently an uninitialised pointer.

Stick with dlkfjdlkfjdlfkd's suggestions

Only one of those lines produces the error.
Every error generated by the compiler has a line number associated with it. Figure out how to goto a line number in your text editor and study carefully.
