>Description:

Hi,
I am a newbie to netbsd and have a question about compiling netbsd source for
the rumprun unikernel; the error message is listed at [1].

I think there may caused by this commit [3]. However, due to my limited
knowledge, I could not solve this. Could anyone help? Thanks.

>How-To-Repeat:
To reproduce the error, you can follow the following steps

1. Download rumprun unikernel source [2]
   git clone https://github.com/huikang/rumprun.git
   cd rumprun
   git checkout add-tuntap
   
2. Checkout the src-netbsd
   git clone https://github.com/huikang/src-netbsd.git
   cd src-netbsd
   git checkout appstack-src
   
3. Compile the rumprun unikernel
   ./build-rr hw

Then if I use the compiled rumpbake to back rumprun unikernel image, it gives
me the following error
