Good resources, but no solution:

[lt3stus3el]

Use this:

export PTX_CRATE_BUILDING=1

i.e.:

rustup install nightly
rustup target add nvptx64-nvidia-cuda
cargo install ptx-linker
git clone https://github.com/dr-bonez/tor-v3-vanity
cd tor-v3-vanity
export PTX_CRATE_BUILDING=1
cargo +nightly install --path .

Now it will compile!
