HP compiler question ?

[Charles Harris]

Dear all,

Just a quickie.....

I am trying to write a small function in C to speed up reporting, to chop up selected data rather than using awk (too slow).
I am having problems working out (cc) - how the compiler works - it doesn't seem to accept proto typing or
normal passing of parameters. Does anyone know how the compiler passes parameters or if there is another that does?


Any help, tips, comments warmly received as ever!

Cheers,

Hi ChaZ,

May you please post the sample that you use and which is not working just for speeding the debug process for what you are doing ?

Normaly, cc is working fine.

Hi Charles:

I suspect that you are using the bundled c compiler; all it speaks is K&R so no prototyping. You will need to buy the ANSI/C compiler of aC++ if you want ANSI features. For such a trivial task, the bundled C compiler should suffice but you will have to convert your function parameters to K&R style.

I would also look into coding your routine in Perl. Perl p-code is very efficient and I suspect it will be almost as fast as doing it
in C unless you are doing some really heavy duty stuff like building a compiler.

Thanks again for the tips, I was trying to use the standard compiler, I'll do it in perl, it's probably easier anyway!
As for the writing of my own compiler...... I'll leave that to the trusty hands of the HP ladies and gentlemen!

Cheers!

Note that the default C compiler is a K&R compiler, not ANSI. SO if you use ANSI structures and protoypes, the compile will flag these as incompatible. You'll need to purchase the ANSI compiler or download the GCC compiler from devresource.hp.com
