@Muqi-Zou I have not tested on my computer but about your logs and the errors you should use the nightly toolchain for radeco.

Try:

rustup toolchain install nightly;
rustup default <nightly full name>;

cargo build;

Did you solve the issue on your computer? Are you sure it might not be related to your system?

[STashakkori]

The errors OP is getting is using an older toolchain. I'm running with nightly and get a different set of errors:
