Can't compile dforce kernels - get linking error

dave_4131166

Hi,

I've just started using DAZ and I wanted to play with Dforce for fabric draping.

When I click on "simulate" I get a message saying I need to compile my DForce Kernel. Fair enough, except that it fails to compile.

Looking at my log file, It seems the linker doesn't like something:

lld: error: undefined hidden symbol: find_coplanarity_times

Any ideas what I can do about that?

I've got a Radeon RX5700 XT graphics card if that's important

Thanks in advance for any help anyone can give on this.

Have you tried a newer/older driver version for the GPU?
