Hi Jerry,
I put "lsocket" in command line with gcc, it does not compile and creating
the message that I put them in a file.
The syntax I used:
gcc -lsocket http_get.c -o http
It does not create the object file http, I attched the message file.
Please rescue and let me know that I should use differnet syntax for
compilation.
Thanks again.

Hi Morris,

Somehow, I never before encountered the need for "-lnsl",
but libnsl.a contains the missing "gethostbyname".  I think
it will work after this.

Re: compilation [afterthought/clarification]

Hi again, Morris,

Just to be sure I haven't been too vague - which, it occurred to
me on rereading this, might have been the case - the correct
and complete command to build this module is as follows:

gcc http_get.c -o http -lsocket -lnsl

I'll be offline most of this weekend.  You shouldn't have a
problem with compilation errors from this point on, but if
you still have any other unsolved problems by Monday,
I'll try to help out if I can.

Jerry
