cc (COMPAQ C V6.5) default warning level

[berlioz]

Hello,

i've recently migrating an application from an Alpha OpenVMS 6.1 (c version ?) to an Alpha OpenVMS 7.2-3 server with COMPAQ C V6.5 compiler.

When re-compiling existing source on the new machine i've "noisy" warning or information message.

Is ther a way to define "default" warning level for that compiler ? in a special conf file ?

thanks in advance for all
Philippe

Not that I'm aware of, and those warnings usually mean something that you really ought to pay attention to and fix in your code. If you must, I suppose you could define a symbol for the CC command that restricts your warning level to something less than the default:

$ cc :== "cc/warnings=level2"

See

$ help cc/warnings

for more information on the warning levels. If there is a standard header file that everything in your application includes, you can control the warnings with "#pragma message".

the warnings produced by the compiler are worth reading and trying to fix. The newer compiler is trying to be helpful.

Philippe,
I'm with Ian. New compiler makes useful checks. If you look at them you'll be able to avoid some potential bugs; e.g. new compiler check for casting pointer and variable size. Also it warn you all unused local parameters and variables.
I know it's a very bored job but it's very useful.

Wish you Happy New Year!
