SolidOak failed to compile with rust nightly

[alsam]

Hello, SolidOak failed to compile with

rustc --version
rustc 1.6.0-dev (b6b17c989 2015-11-14)

The error message:

../.cargo/git/checkouts/cairo-571ad16295201b7a/master/src/image_surface.rs:39:37: 39:49 error: no method named `as_mut_ptr` found for type `&mut image_surface::AsyncBorrow<Box<[u8]>, F>` in the current scope

Strictly speaking the error message appeared during cairo-rs compilation.

   Compiling cairo-rs v0.0.4 (https://github.com/rust-gnome/cairo#8c562274)

Follow crates.io the latest cairo-rs crate is 0.0.6 and it should compile with nightly rust. From https://github.com/gtk-rs/cairo

cairo build passing

will check it, Thanks

Hi, sorry for the newbee question. I have a similar issue:

$ rustc --version
rustc 1.7.0-dev (21b025f55 2016-01-06)
$ cargo --version
cargo 0.8.0 (ca37345 2016-01-06)
$ cargo build
.....
/home/iuliuv/.cargo/registry/src/github.com-88ac128001ac3a9a/rustc-serialize-0.3.15/
src/serialize.rs:201:5: 201:64 error: the trait `core::marker::Sized` is not implemented 
for the type `Self` [E0277]

looks like a problem with the serialize-0.3.15. There is a serialize-0.3.16, but I am not sure how to make SolidOak use it for compilation. The one think I tried ended in a new error:

Hi @iuliuv, you are quite right, the same for me:

looking into Cargo.lock noticed

less Cargo.lock
name = "solidoak"
version = "0.1.3"
dependencies = [
 "gdk 0.1.1 (git+https://github.com/rust-gnome/gdk)",
 "glib 0.0.3 (git+https://github.com/rust-gnome/glib)",
 "gtk 0.0.3 (git+https://github.com/oakes/gtk)",
 "libc 0.1.8 (registry+https://github.com/rust-lang/crates.io-index)",
 "neovim-rs 0.1.0 (git+https://github.com/oakes/neovim-rs)",
 "rustc-serialize 0.3.15 (registry+https://github.com/rust-lang/crates.io-index)",
]
...
[[package]]
name = "rustc-serialize"
version = "0.3.15"
source = "registry+https://github.com/rust-lang/crates.io-index"

generally as a quick-n-dirty fix I would s/0.3.15/0.3.16/g in Cargo.lock

after it

so rust-serialize has the correct version 0.3.16 but anyway compilation is broken in other places. Hope this helps.

Not sure if it compiles with the nightly yet but I just updated gtk-rs and neovim-rs so it builds with the latest stable release of rust.

[iuliuv]

Worked brilliantly, with the latest dev, too! Thank you!!

[alsam]

Confirm, built ok with the nightly. Thanks a lot! Closing the issue.
