Now it's says :

./gcc: Invalid argument

I'm trying to run it from /usr/local/bin where i can find the gcc command.

Any other ideas ?

Please assist.
Thanks !

Not sure where "Invalid argument" would come from, but...

Code:
# /usr/sfw/bin/gcc
gcc: no input files

Like you, I have:
Code:
# uname -a
SunOS sol10 5.10 Generic_141445-09 i86pc i386 i86pc

I've managed (i think) to install the gcc.
Now i'm trying to complie this piece of code (which were found in several forums for changing the host id):

Code:
#include <stdio.h>
#include <unistd.h>
int main(int argc, char *argv[])
{
if(argc < 2)
{
fprintf(stderr,"Single argument: Target hostid\n",argv[0]);
return 1;
}
sethostid(
strtoul(argv[1],NULL,16) );
return 0;
}

but now i'm getting this kind of an error:

Code:
# gcc change_hostid.c -o change_hostid
Undefined first referenced
symbol in file
sethostid /var/tmp//ccEX9dSj.o
ld: fatal: Symbol referencing errors. No output written to change_hostid
collect2: ld returned 1 exit status

As i mentioned i've quite new with the Solaris and really i'm not a code guy.
Any idea what can be the problem for this simple code not to compile ?

BTW, i've managed to compile this short code successfully on a RedHat Linux server.

Please kindly advise.

Agreed, sorry for the unhelpful/rude comment. I guess I was in bad mood been stuck by snow ...

Anyway, gcc is part of the default Solaris installation if you select one of these software groups: Developer, Entire, Entire plus OEM. These choices are certainly the most frequent ones, compared to End User, Core or Core with reduced network. The fact is a large majority of people complaining about a missing gcc on Solaris 10 are just missing to add /usr/sfw/bin to their PATH.

And to sethostid:

Quote:
4.3 BSD has gethostname() and gethostid(), which return a symbolic name and a numeric value, respectively. There are related sethostname() and sethostid() functions that are used to set the values the other two functions return. The former functions are included in this specification, the latter are not.
The Open Group Base Specifications Issue 7


Quote:
4.2BSD. These functions were dropped in 4.4BSD. POSIX.1 does not define these functions, but ISO/IEC 9945-1:1990 mentions them in B.4.4.1. SVr4 includes gethostid but not sethostid.
