I get the an "undefined identifier destroy" message when trying to compile the following with GDC.

void main()
{
    X x = new X();
    destroy(x);
}

...but it compiles fine in DMD 2.065.0.

I'm using a week-old build of 4.8.2.  Is this not implemented yet?

Mike

just checked it with todays GDC git and gcc 4.8.2 — it works ok.

Thanks for the reply.

I just rebuilt, and I get the same error.  Are you using the GDC 4.8 branch with GCC 4.8.2?

My build is an ARM Cortex-M cross compiler, but the latest Arch Linux 64 GDC package also fails with the same error.

Destroy was added to druntime years ago: https://github.com/D-Programming-GDC/GDC/blame/gdc-4.8/libphobos/libdruntime/object_.d#L2257

(It's implemented in the library, so if you want to use it on bare-metal without druntime you'll have to rewrite it ;-)

that's it. you have to implement it yourself then, 'cause there is no druntime, unfortunately.

Ah! silly me.  Thank you.  I expected a link error, though, for a missing library function.

destroy() is not a built-in, actually, it's just a template, which calls finalizer (see object.di in GDC source). so compiler have no way to know that it should do something special with this identifier.
