Re: [cdt-dev] Common toolchain options

[John MOULE <john.moule@xxxxxx>]

Hi Mikhail & Wieant,

thank you for your responses. I've had a play around, but I'm still not 
getting this.

In my example toolchain (attached) I have compiler and link tools. In 
each there is a string option, Option1, which when I alter in one of the 
tools, say the compiler, I would like the same Option1 in the other 
tool, the linker, to reflect this value.

It seems that this would be a common thing to want to do, although the 
GNU toolchain doesn't seem to have any shared options.

So in the EVENT_APPLY part of my ExToolManagedOptionValueHandler() I 
want to read the changed option value from one tool and apply it to the 
twin option in the other tool. I imagine there must be a simple approach 
to this???

cheers john
