Change rustc output name with command line argument

[jovial loom]

I aleary tried -o option, but my final file *.a didn't change, only *.d filename is changed

Why doesn’t -o work?

https://doc.rust-lang.org/rustc/command-line-arguments.html#-o-filename-of-the-output

[jovial loom]

-o produce changed name.d and origin.a is not changed. I use crate type staticlib

In cargo you just set the name https://doc.rust-lang.org/cargo/reference/cargo-targets.html#configuring-a-target

but i want to change name in cli since i use cargo rustc --lib --crate-type staticlib -- --cfg 'test' to inject cfg

Oh I delete first message by mistake, first message was tried to change output filename in command line argument

You will probably have to run the rustc command by hand, cargo's going to really mess with anything you do
