Programming

Post the exact command that you are using to compile the code. Post the exact text of any results that you get.


I don't have access to an AIX system. But I've tried that code with 4 compilers on two different OS's and I can't get it to fail.

Your include file would seem to be:
#include <unistd.h>
But's that the case on HP-UX too. HP-UX compiles it because the other include files seem to bring it in. I also did not need to add an include file on SunOS.

You might give that a try though. Look at the the top of the program. Right after the comment comes the include files. There are three lines that start out "#include". You need to add a fourth line.

But I'm thinking that you have some other problem.

Hmmmm, this is where my newbie Unix experience begins to show. Sorry about this. I thought I could copy the code from the internet, use vi to create a file called convdate, paste in the code and change the file properties to become executable. This file will be in the same directory as the script that I'm running.

I guess this is very wrong. Any advise would be welcome.

Very wrong would be an understatement. I don't know AIX so I can't help you keystroke by keystroke. But in general you need to copy the code from the internet and create a file called convdate.c. Then you need to to compile that into an executable. Maybe your compiler is called "cc" and maybe it's on your PATH. Try this:

cc convdate.c -o convdate

If that works, great! Otherwise, you will need to find an AIX expert.

Thanks for the advice. Had a feeling I was way off track.

Think the code you gave me would work. Tried typing cc and got the message that I don't have execute permissions.

Think I might be out of my league now. I am only a standard user on the system. However, being a VB programmer with a very weekly manual process I thought I could automate it. Went on a Unix course before christmas and it looked quite straightforward. Little did I know our version of Unix wouldn't have convdate nor does it have a personal cron file. I very much doubt I'll have access to the system cron so I might just give up. Good bit of tinkering whilst the office is quiet over the christmas period.

Looks like I won't be able to compile the convdate function code. Think I might just give up.

Sound good to you? Feel free to convince me otherwise! Beginning to feel that my VB is much much easier!
