Unfortunately there is no simple answer. Your source code is written in ANSI C but the bundled C compiler on;y 'speaks' the archaic K&R C dialect. You need to purchase an ANSI C compiler (or the aC++ compiler) from HP or download and install gcc from
http://gatekeep.cs.utah.edu/hppd/hpux/.

You will get this error using the standard cc which ships with HP-UX. YOu need to get HP-ANSI C or... Gnu EGCS.

If you get egcs, make sure to get the bin-utils with it, and any other pre-reqs you see!

gcc --version

should give the version info. If it does not, gcc is not in your $PATH

If you get the same errors, it's because you are still using the bundled compiler (cc) rather than gcc.

Do this:

Create a text file hello.c

int main(int argc, char *argv[])
{
(void) printf("Hello world. Argc = %d\n",argc);
return(0);
}

gcc hello.c

You should get an executable file. If it executes you are all set.

You then need to make sure that your application makefile calls gcc rather than cc. Most packages have a configure script that you can run toi create the makefiles.

in (t)csh:

setenv PATH $PATH:"/your/path/to/gcc/bin"

in (k)sh:

export PATH=$PATH:"/your/path/to/gcc/bin"

best to do this in your ~/.profile (for (k)sh) or ~/.login (for (t)csh) or - even better - add the path in /etc/PATH, so all of you get it all the time.

The sequence is important here. Commands will be found in the first path it resides.

You can't exectute 'hello.c' that the source file but you should see a file (probably called a.out) which is executable.

You can do this to specify an output file (with -o).

gcc hello.c -o hello

Now you should be able to execute 'hello' and get the expected output.

Stephenson ,,
still not working
any aother way

# cat hello.c
int main()
{ printf("Hello\n"; }
# gcc -o hello hello.c
# ./hello

if you are using a (t)csh, you should use

# rehash

after you have changed your $PATH

type

# which gcc

to check if it is in your path. If it cannot be found, you get an error message like

gcc: command not found

otherwise it will show the path to gcc, like

/usr/local/bin/gcc

the first part (/usr/local/bin) should be in your $PATH. You can check that with

# echo $PATH
/bin:/usr/bin:/some/path:/usr/contrib/bin:/usr/local/bin:/opt/foo/bin

if that first part is in there, you should be able to complete the compilation as I started this post.

If you updated your path properly in the .profile, you must start a new session to have that profile read.

You should have added the paths to this file like this...

echo "PATH=/opt/egcs/bin:/opt/gnu-binutils/bin:$PATH" >>/.profile
echo "export PATH" >>/etc/profile

NOTE: MY DIRECTORIES ARE HYPOTHETICAL, MAKE SURE THEY EXIST.

If you do this then log out then back in you will be able to check to see if it's correct.

% which gcc
/opt/egcs/bin/gcc

If you can not use the which command to find gcc, then your path's are still bad.

I'd suggest you look at "Unix in a Nutshell, published by O'Reilly and Associates". It has some basic tips/trics for shells and basic unix commands.

Dear procura

i have made what u said , everything is fine except the hello.c

gcc is running it is in my path when i run #which gcc it gives me the path
but when i excute
gcc -h hello hello.c
it is gives me
( # gcc -o hello hello.c
as: warning 2: Unknown option "--traditional-format" ignored.
as: "/var/tmp//ccVjkgzc.s", line 22: error 1052: Directive name not recognized - NSUBSPA
#

the hello.c is as the followig :
int main()
{ printf("hello\n"); }

any ideas
thank you

gcc -h???? That must be a typo.
