Get only cache misses

[siscia]

Hi,

I am trying to use sccache, but I am keeping getting only Cache Misses.

# sccache -s
Compile requests                        243
Compile requests executed               170
Cache hits                                0
Cache misses                            164
Cache timeouts                            0
Cache read errors                         0
Forced recaches                           0
Cache write errors                        0

Average cache read hit                0.000 s

Non-cacheable reasons:
crate-type                               61
-                                        12

Is that normal/ok?

The project I am building this project: https://github.com/RedBeardLab/rediSQL

It is a cdylib project, does it change anything?

I don't know much about sccache, but you probably should mention what platform you're building on. For example, I noticed that there's a known issue (#169) on macOS.

Thanks! Well Linux for x86_64

The "standard".

I've seen the same happening. cdylib project (specifically, building for the wasm target). macOS.

It's a known problem that sccache doesn't work well with cdylib deps. Visit our docs for more information: https://github.com/mozilla/sccache/blob/main/docs/Rust.md

We are working on solution to fix this.
