Warning C1801: Implicit parameter-declaration

BasePointer — Fri, 05 Oct 2007 16:16:02 GMT

Hi,

I'm using CW6.0 and HCS08 C.

The compiler generates warnings for my application "Warning C1801: Implicit parameter-declaration".

And this warning causes my application not to work properly.

I want to take compile error with this warning. Is this possible?

Thanks.

Hello,

It is possibke to compile without warnings.
The fault is not because of the warning, but probably because you use a function in your code and you did not declare the function prototype before.

Warning and Error codes are very useful as they are described in the help of CodeWarrior.

C1801 means Compiler error. Lxxxx would mean a linker error...

Hi Alban,

My project is huge and as you said I sometimes forget adding functions prototypes.

I can compile entire project successfully even if I did so.

I want compile process to fail if this warning exists for any modules of the project.

Or can I see all warings of modules in a list?

I can easly search C1801 in this list.

Regards,

BP.

Hi,

Standard Settings... -> Compile for HC08 -> Messages -> Warning Tab and I moved C1801 to the Error.

Now I'm taking compile error with C1801. This is exactly what I want.

Thank you.

BP.

Hello,
there is as well the compiler option
-Wpd Error for implicit parameter declaration
under the MESSAGE tab which will flag implicit parameter declarations as error.

Hi,

I also wonder if I can do this with #pragma directions?

Thanks.

Hi,
yes, there is a #pragma way for this

something like
#pragma MESSAGE ERROR C1801
(see manual/help files for details).

The other way is to use the
#pragma OPTION ADD xx "-Wpd"
way.

That works:

#pragma MESSAGE ERROR C1801 // Implicit parameter declaration

Thank you so much.
