Hi,

what does it mean “rejecting the pragma directive”

For example, with this source code...

int main(void)
{
 #pragma message "Fix it!!!"
	for(;;);
}

... the compiler output is

make all
'Building file: ../src/main.c'
'Invoking: MCU GCC Compiler' ...
../src/main.c:19:9: note: #pragma message: Fix it!!!
 #pragma message "Fix it!!!"
         ^
'Finished building: ../src/main.c'

Is it not what you expect?

Regards,
Stefano

What is the meaning of the caret symbol below the first letter of the “message” token? This caret looks to me to be an error indicator. The message token is not included as valid for #pragma in the “ARM Compiler toolchain Compiler Reference”:
http://infocenter.arm.com/help/topic/com.arm.doc.dui0491i/DUI0491I_arm_compiler_reference.pdf
which I found after starting this thread.

When I used “#pragma message ...” these did not appear in the output under the Console tab in the expected order. This is another indication to me that this is an error message, and not a message directive the compiler was executing.

I ended up doing what I needed to do with the #warn directive. These gave me the expected results and were useful in finding the source of the compiler errors I was seeking.
