You have forgotten the a main () clause. The compiler needs to know where to start the program, it's not as simple as other languages where the program starts at the first line. ;-)
Most likelly you'll wan't to return the result of you computation also.

Ämne: [C400-L] basic C question
Pardon my ignorance. I just can't seems to be able to figure out why
this will not compile:
#include <string.h>
#include <unistd.h>
char hostName[256];
int hostNameLen;
hostNameLen = sizeof(hostName);
gethostname(hostName, hostNameLen);
exit(0);
Below is portion of the compiler error:
4 |
5 | char hostName[256];
6 | int hostNameLen;
7 |
8 | hostNameLen = sizeof(hostName);
===========>
.a......................................................................
