Help compiling c code into "PA-RISC1.1 shared executable dynamically linked -not stripped" files

TechC — Mon, 19 Jan 2009 00:46:26 GMT

Hi list,
I have a HP-UX 10.20 box that I want to move to 11.11.
This box uses cgi scripts for the http installation that are "PA-RISC1.1 shared executable dynamically linked -not stripped" files when I issue the file command against them.
I do have the c code and I need to make some changes to it because some paths need to be changed to reflect the new environment. After that I need to recompile it back into PA-RISC shared executables.

What commands do I use to turn these .c files into PA-RISC shared executables?

I obviously am not a programmer but I just need to change hard set paths in the c code and recompile them. Can you help me?
I am pretty lost here, I assume the cc command should be used but not sure.

Thank you
James

Are your executables composed of single source C files?
Do you have the C compiler installed or the bundled C compiler?
For the simple case, you should be able to use:
$ cc -o executable foo.c

Dennis,
Thank you for responding.
I have what look to be single c source files.
so I have a cgi script named brakes.cgi and I found the c source code named brakes.c

For the C compiler I believe it is the bundled or "standard issue" C compiler.
I found a string I think was used to compile the original cgi scripts from the c code.
It is...
"cc -Aa -g cgia.c license.c -lm -o cgia

From the man page it looks like -Aa is saying use ANSI mode. -g is to generate info for the symbolic debugger. I understand that -o cgia is outputting cgia as the executable.

But can you help me to understand what the -lm does. It says something similar to "resolve unresolvable external references"
I am not sure what to make of that.

Thank you again

The bundled C compiler on PA will not support -Aa nor -g.

>But can you help me to understand what the -lm does.

It links in libm so you can call functions like sin(3).

Dennis thanks again.
OK thanks for the heads up on the -lm.
How can I get the c compiler I am looking for?
Is it simply downloadable from ITRC in .depot format.

Thank you
James

If your code is simple, you can attempt using the bundled compiler.

You have to purchase it. There is an evaluation copy available:
