Hi, It seems that the Raisonance C preprocessor doesn't support either the "#warning", or the "#pragma message" directive. I can't believe any modern compiler may have no facilities like these, so my question is how can I output a message at compile time?

Hello,

Thanks for the feedback. "#warning" directives doesn't belong to the C standard that why it's not supported. We will try to suppot it in the next release.

Concerning "#pragma" directives, please have a look of our STM8/ST7 compiler manual (page 86) you can find it at C:\Raisonance\Ride\Doc\ST7\RCSTM8.pdf

I hope it helps.

Regards,

Does that mean there is currently no way to output a message at compile time?

For the moment you can use "#error" but it will stop the compilation.

We will integrate this option in the next release which will be released in September.

Best Regards
