Dynamic_cast compile error -fno-rtti

I am using this in my code:

NumericMenuItemInt* p_nmi = dynamic_cast<NumericMenuItemInt*>(p_menu_item);

But I get the following compile error:

'dynamic_cast' not permitted with -fno-rtti


How do you enable this in the compiler options?

Regards,

David

Hi,

Switch on vmicro>compiler>"verbose" and "show build properties" then build and this will show us which tool chain you have installed and what options it has configured.

You can email the output as a .txt file or post here. Email is info[at]visualmicro.com

Hopefully you have received the log.

I am using an Arduino Mega.

If I recall the more recent Arduino mega defs have this setting so try an older tool chain for Avr in board manager

Hi,

This error could have been caused if the latest arduino hardware defs were used with an older avr toool installation. 

The recent version(s) of visual micro were updated to detect and resolve the issue. So if yo upgrade you will find that issue is resolved.

The issue only hit a few users but I thought I would mention it in case it was why you raised this thread.

If using visual studio then update visual micro from the gallery

If using atmel studio update using the next-release link on our downloads page

Thanks
