Compiling on Linux Mint 21 / Ubuntu 22.04

[lennart-g]

Hi, I am new to Rust (and to ENSnano) and wanted to run it on Linux which sadly does not come with an executable.

I tried building it as described in the README but failed with the following output:

$ cargo run --features=log_after_renderer_setup --release
    Updating crates.io index
    Updating git repository `https://github.com/thenlevy/chebyshev_polynomials`
    Updating git repository `https://github.com/termhn/ultraviolet`
    Updating git repository `https://github.com/nical/lyon`
    Updating git repository `https://github.com/rust-cli/confy`
error: failed to select a version for the requirement `iced_aw = "^0.2.0"`
candidate versions found which didn't match: 0.7.0, 0.6.0, 0.5.2
location searched: crates.io index
required by package `ensnano_gui v0.4.0 (/path/to/ensnano/ensnano-gui)`
perhaps a crate was updated and forgotten to be re-vendored?

Looking at https://docs.rs/iced_aw/0.2.0/iced_aw/index.html, the required version is apparently no longer available. I tried editing ensnano-gui/Cargo.toml and ensnano-organizer/Cargo.toml to 0.7.0 (and in another attempt to 0.5.2) which both did not compile.

What ultimately allowed me to build and run ENSnano was to clone iced_aw, checkout version 0.2.0 and cargo build --release. I then updated the entries for iced_raw in ensnano-gui/Cargo.toml to iced_aw = { path="/path/to/iced_aw", features = ["tab_bar"]} and in ensnano-organizer/Cargo.toml to iced_aw = { path="/path/to/iced_aw", features=["icons", "icon_text"] }.

$ rustc --version
rustc 1.72.1 (d5c2e9c34 2023-09-13)
$ cargo --version
cargo 1.72.1 (103a7ff2e 2023-08-15)

Maybe this will be useful to others. Please let me know if this approach is flawed and what is considered the better way to build ENSnano on Linux.
