An innocent C/C++ programmer trials

[vortex314]

I'm very much interested in the features of zenoh for my robot hobby project, however unwilling to invest in Rust.
So this is from a C/C++ programmer POV.

Compiling spinning_top v0.2.4
error[E0658]: use of unstable library feature 'renamed_spin_loop'

Ok, seems linked to use of unstable versions.
Installing rustup...

lieven@pcpav2:~/workspace/zenoh-c$ sudo snap install rustup
error: This revision of snap "rustup" was published using classic confinement and thus may perform
       arbitrary system changes outside of the security sandbox that snaps are usually confined to,
       which may put your system at risk.

       If you understand and want to proceed repeat the command including --classic.
lieven@pcpav2:~/workspace/zenoh-c$ rustup toolchain install nightly 
Command 'rustup' is available in '/snap/bin/rustup'
The command could not be located because '/snap/bin' is not included in the PATH environment variable.
rustup: command not found

gives confidence to the beginning user.. ;-)

After installing the dependecies,

 2263  sudo snap install rustup
 2264  rustup toolchain install nightly
 2265  sudo snap install rustup --classic
 2266  rustup toolchain install nightly 
 2267  export PATH=$PATH:/snap/bin
 2268  rustup toolchain install nightly 
 2269  rustup default nightly
 2270  cargo install cbindgen
 2271  export PATh=$PATH:/home/lieven/.cargo/bin
 2272  make

still the same issue : ```

Hi @vortex314!

zenoh requires a recent Rust stable version. The Rust version shipped with Ubuntu is quite old and it gives some headache when compiling (see eclipse-zenoh/zenoh#94).

Please install the latest Rust version following these instructions.

[vortex314]

Ok, will try that.

Thanks for your help @Mallets , compile issue solved !
