Handle warnings and/or messages.

VianneyC — Mon, 09 Jul 2007 17:29:33 GMT

Hello,

I am working with CodeWarrior 5 and a HCS08 microcontroller, porting some code from Cosmic.

I wonder how is it possible do handle - e.g. - a warning message during the compilation to avoid his appearence in the compilation tab.
For example :
I have this instruction : "time_ref_mng();" , that generate the "C4301: Inline expansion done for function call" message. I don't want to modify the code to cancel the message when compiling, but only tell to the compiler that this situation is normal. Do you understood what I want to do ? Someone can give some advices and/or indications how to do ?

Thanks.

Hello,
there are several ways, but probably you want to use the -Wmsg compiler option:
-WmsgSd4301
disables the message 4301.

See the -Wmsg option where you can move messages around (to disable, to warning, to error, etc).

Otherwise you could use the
#pragma MESSAGE DISABLE C4301
but for this you would have to put that into your sources where you want to disable the message.

Another way would be to put the above pragma into a header file (e.g. message.h) and then have it included for all your files you compile, using the -AddIncl compiler option:
-AddInclmessage.h

I decide to use this solution :

#pragma MESSAGE DISABLE C4301
time_ref_mng();

But, is that possible to add this sentence after, #pragma MESSAGE DEFAULT, i.e :

#pragma MESSAGE DISABLE C4301
time_ref_mng();
#pragma MESSAGE DEFAULT

I want to disable the message only for one instructions.

Hello,
the #pragma MESSAGE is on a per function base, so it will be valid for the whole function. You would need to place it before/after the function:

#pragma MESSAGE DISABLE C4301
void myFunction(void) {
...
time_ref_mng();
...
}
#pragma MESSAGE DEFAULT C4301

Hi ,

I am also working on CW v 6.compiler for HCS08 family. I am also facing one error message that

C4301: Inline expansion done for function call. i am using a function which was INLINE.

I am using the option you have mentioned above.

But still facing the same error. but the error message still exists.

#pragma MESSAGE DISABLE C4301

Initialize_HWIO_APPLStack();
#pragma MESSAGE DEFAULT C4301

But if i use the second option, the warning was gone. The second option is used was -WmsgSd4301

Please let me know why i am not able to eliminate the warning with the 1st option.
Are there any settings do i need to set?

Hello

The pragmas MESSAGE DISABLE and MESSAGE DEFAULT must be use prior and after the function, which invokes Initialize_HWIO_APPLStack.

Not around the prototype for the function Initialize_HWIO_APPLStack

I am using befoere and after the inline function call where i am calling from the Main fucntion.

But even though i am seeing the warning

void Reset_Interrupt (void)
{

#pragma MESSAGE DISABLE C4301
   /* Initialize stack and Set Stack Pointer to start of stack area */
   Initialize_HWIO_APPLStack();
#pragma MESSAGE DEFAULT C4301
   /* Determine the cause of reset source */

}

Thanks. I tried the below one and it works.

#pragma MESSAGE DISABLE C4301

void Reset_Interrupt (void)
{

   /* Initialize stack and Set Stack Pointer to start of stack area */
   Initialize_HWIO_APPLStack();

   /* Determine the cause of reset source */

}

#pragma MESSAGE DEFAULT C4301
