[BUG] Cant build feroxbuster on ARM

[tienna-0051]

Describe the bug I'm trying to build feroxbuster on the raspberry pi but run into an error with serde

To Reproduce

Raspberry Pi 3 Model B+

➜  feroxbuster git:(main) rustup show
Default host: armv7-unknown-linux-gnueabihf
rustup home:  /home/pi/.rustup
stable-armv7-unknown-linux-gnueabihf (default)
rustc 1.49.0 (e1884a8e3 2020-12-29)

➜  feroxbuster git:(main) cargo build --release
   Compiling feroxbuster v2.2.2 (/home/pi/sectools/feroxbuster)
error[E0277]: the trait bound `AtomicUsize: Deserialize<'_>` is not satisfied

At https://serde.rs/derive.html#troubleshooting, the docs suggest to "upgrade or downgrade libraries as appropriate until the Serde versions match" but cargo tree -d return nothing. Can you check this?

Thanks for the report! I'll take a look tomorrow

Good morning,

I've added a dynamically linked armv7 build to my CI pipeline (link to the built binary below). Can you give it a try and see if it works on your end?

For whatever reason serde won't derive Serialize/Deserialize on atomics for arm, so I wrote a custom [de]serializer for the Stats struct. My tests still pass using an x86 binary, but I don't know if they truly pass on an arm host.

Could you try the following and make sure nothing goes haywire?

• start scan with save_state enabled (default is true)
• let it run for a bit and then ctrl+c, this will hit the serialization of the Stats struct
• resume the scan using --resume-from STATE_FILE, this will hit the deserialization of the Stats struct

If everything looks ok for you, ill merge to main.

Hi,

I ran a test with the new artifact on my raspberry pi, and it seems working correctly 👍 Log: https://pastebin.ubuntu.com/p/b8cCSYsX72/
