how can I fix this? And what file type are the binaries for macOS in the releases?

Hi @neurons9, this is pretty weird, mac M* family should be aarch64, there is a binary available on our release CI if you want to try.

How did you install Rust in your computer ? Did you follow the book ?

Hi @patrickelectric, thanks for your quick reply!
I have installed Rust with the command:
curl https://sh.rustup.rs -sSf | sh
What file types are the binaries? I can't open or run them...
ah got it... sorry

[patrickelectric]

I only have a mac m1 but I can compile fine here, from the issues that you are pointing, may be a dependence break or something.
Try to cargo clean, cargo update and cargo build

@patrickelectric got a similar issue on Linux. Tried to repro on:

1. Gentoo (rustc version 1.71.1)
2. Docker rust (rustc version 1.81.0) clean repo
3. Ubuntu (rustc version 1.75.0)

I'm not a Rust coder so I have a limited way of debugging the build, but the underlying issue seems to be some change done in chrono library, as referenced in actix/actix-web#3135

Specifically this: https://github.com/chronotope/chrono/releases/tag/v0.4.30

I tried pinning it to 0.4.29, but for some reason cargo install still pulls the latest one whereas cargo tree does understand what I want. Apparently upgrading actix to v4 might also help, but that sounds terrifying for me.

Hi @landswellsong I was able to build using ubuntu 22.04 from a fresh installation:

root@7ab75cc00ae8:/mavlink2rest# history
1 apt update -y
2 apt install -y curl
3 curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
4 . "$HOME/.cargo/env"
5 apt install -y git g++ binutils
7 git clone https://github.com/mavlink/mavlink2rest
8 cd mavlink2rest/
9 cargo build
10 history

Hello @patrickelectric

This does work. I think cargo install , cargo build and cargo tree all use a different dependency logic? I was using install as specified in the README.

That being said it seems that actix-web is pulled in twice:

   Compiling actix-web v4.9.0
   Compiling hyper v0.14.30
   Compiling actix-files v0.6.6
   Compiling actix-http v2.2.2
   Compiling hyper-rustls v0.24.2
   Compiling reqwest v0.11.27
   Compiling git2 v0.16.1
   Compiling awc v2.0.3
   Compiling actix-web v3.3.3

May there be a merit of bumping it to v4 in this project's dependencies? Seems like that would solve this issue and apparently mavlink2rest already can work with v4.

[patrickelectric]

Yes, that would be possible, but timewise is tricky. At the moment I'm working on other projects, but be free to collaborate with it.
