Reproduction

At present, the sid branch of debian has riscv software repository, but there are some problems switching from stable to sid, and the switch cannot be passed. Although it is possible to create sid for amd64 using mmdebstrap, libssl-dev and libwebkit2gtk-4.1-dev for installing riscv64 have dependency issues. So I used mmdebstrap to create a debian for riscv64.

sudo apt install mmdebstrap qemu-user-static binfmt-support
sudo mmdebstrap --architectures=riscv64 sid rvrootfs "deb https://mirrors.tuna.tsinghua.edu.cn/debian sid main"
sudo chroot rv64rootfs/

apt install gcc lld libssl-dev libwebkit2gtk-4.1-dev

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
cargo create-tauri-app --beta # select leptos
cargo install tauri-cli --version '^2.0.0-beta'
cargo install trunk
rustup target add wasm32-unknown-unknown

fix no rust-lld：https://stackoverflow.com/a/78401428/12910074

cd xxx
# change `identifier` in src-tauri/tauri.conf.json
cargo tauri build

If trunk build step report wasm-bindgen download error, do cargo install wasm-bindgen-cli
