Rocket: Please help me for build project

[sinitcin]

Hello! I use Win10 x64 pro and last rust nightly. I would like to use Rocket version 3.15. My Cargo.toml:

[package]
name = "sci_questionnaire"
version = "0.1.0"
authors = ["Антон Синицын <[email protected]>"]

[dependencies]
rocket = { git = "https://github.com/SergioBenitez/Rocket" }
rocket_codegen = { version = "0.3.15", git = "https://github.com/SergioBenitez/Rocket" }
serde = "*"
serde_derive = "*"
serde_json = "*"
sqlite = "*"

[dependencies.rocket_contrib]
version = "0.3.*"
default-features = false
features = ["handlebars_templates"]

And i have build error:

 cargo build --all-features
    Updating git repository `https://github.com/SergioBenitez/Rocket`
    Updating registry `https://github.com/rust-lang/crates.io-index`
error: no matching package named `rocket_codegen` found
location searched: https://github.com/SergioBenitez/Rocket
did you mean: rocket_codegen
required by package `sci_questionnaire v0.1.0 (file:///C:/sci_questionnaire)`

My project placed: https://github.com/sinitcin/sci_questionnaire/blob/master/Cargo.toml

Why my Cargo.toml is incorrect? Thank you in advance.

[jebrosen]

Combining git = with version = doesn't usually do what you want. If your goal is to use 0.3.15, rocket = "0.3.15" and rocket_codegen = "0.3.15" are sufficient.

[sinitcin]

But, i have the ring build problem like issue #642 And i use recommendation from this comment - https://github.com/SergioBenitez/Rocket/issues/642#issuecomment-395895257 .

If i not use version i have build error. When I get home I'll write the text of the build errors I get on Win10

[jebrosen]

Oh right, #642 -- unfortunately you cannot use Rocket 0.3.15 on Windows for that reason. If you are having problems using git = alone, we would be happy to help debug those.

[sinitcin]

Okay, i delete "version" from Cargo.toml:

[package]
name = "sci_questionnaire"
version = "0.1.0"
authors = ["Антон Синицын <[email protected]>"]

[dependencies]
rocket = { git = "https://github.com/SergioBenitez/Rocket" }
rocket_codegen = { git = "https://github.com/SergioBenitez/Rocket" }
serde = "*"
serde_derive = "*"
serde_json = "*"
sqlite = "*"

[dependencies.rocket_contrib]
default-features = false
features = ["handlebars_templates"]

And i have new build error:

PS C:\sci_questionnaire> cargo clean
PS C:\sci_questionnaire>cargo build
warning: dependency (rocket_contrib) specified without providing a local path, Git repository, or version to use. This will be considered an error in future versions

Please help me for fix this =(

[jebrosen]

The first warning says you need to specify a version (or git, or path) for rocket_contrib -- you don't have a git = line for that one.

The rest of the error should be resolved as well once you fix that.

[sinitcin]

Sorry, not resolved. Project placed on https://github.com/sinitcin/sci_questionnaire you can clone if this need. New build problem:

The master branch of Rocket has made some changes to its macros and derives that work towards less breakage from rust nightly in the future. One of the side effects is that #[macro_use] is now necessary on the extern crate rocket; line.

[sinitcin]

Hallelujah =) It work. Do you think about update of examples for better quality of code? I do not know English well and it is easier for me to understand the code than the manual. The solution to this problem was not obvious to me, unfortunately. Perhaps, in the future it would be worth correcting Cargo.toml in order to avoid problems with the build ring and rocket_contrib on Win10?

And big thank you =)

[jebrosen]

When Rocket 0.4 is released soon it will "just work", and examples and documentation will be updated. Unfortunately, Rocket 0.3 cannot be fixed in this way without breaking other existing Rocket applications.

It sounds like this issue is resolved for now, so I'll close it out.

[jens1o]

Rocket 0.3 cannot be fixed in this way without breaking other existing Rocket applications.

Is there an UPGRADING file @jebrosen?

[jebrosen]

@jens1o I'm not sure what you mean. Who or what project would provide this UPGRADING file and what information should be in it?

Changing ring from 0.11 to 0.13 is a semver breaking change due to the way ring currently works, so this upgrade will not happen until Rocket also changes its version number from 0.3 to 0.4.

[jens1o]

Rocket also changes its version number from 0.3 to 0.4

You said that there will be breaking changes. I wonder whether I can prepare something for the next release to adapt it as fast as possible?

[sinitcin]

@jebrosen i understand and thank you!

[SergioBenitez]

@jens1o We will have notes on how to upgrade once the release is cut.
