I want to make a GUI application using Rust on Windows 10 and I found the qml crate which looks nice.
I added in my Cargo.toml file this dependency: qml = "0.0.9", but when I run cargo build, I get this error:
> cargo build
Compiling qml v0.0.9
error: failed to run custom build command for `qml v0.0.9`

I looked at the build.rs file and I saw this line:
fs::copy(Path::new(&manifest_dir).join("build_lib.sh"), Path::new(&out_dir).join("build_lib.sh")).unwrap();
Maybe I don't have the rights to do that on my account, so I tried to run it as admin, but cargo and rustc are installed in my user folder.
When I change the path, I get the error error: no default toolchain configured.
QML 0.0.9's build script doesn't support Windows.
It appears that support for Windows was added in 80ccad26, which seemingly hasn't been released yet.
You will need to use the version from the git repository instead:
[dependencies]
qml = { git = "https://github.com/White-Oak/qml-rust" }

The issue I'm having are regarding a copy-pasted flo_draw example program. I am using vscode and the rust-anylizer extension. It tells me failed to run build scripts, check server logs for more information apon copying the code in. I don't know how to check these or what they are. Using cargo run from the terminal yields no better results.
I tried to copy in the code below:
// src.main.rs
use flo_draw::*;
use flo_draw::canvas::*;
fn main() {
with_2d_graphics(|| {
let canvas = create_canvas_window("Hello, world");
});
}

flo_draw, or, more specifically, one of its dependencies, links to the external C library and therefore have to generate the matching API. This is done using bindgen, which requires clang to be installed in your system.

My company just switched on a new repo the Rust project I'm working on, to merge it with a Tauri project, and VS Code now gave me this error:
Failed to run build scripts
I can compile, run my project or use cargo check to see the warnings/error but Rust Analyzer is not working and it's very annoying for me to run cargo check every time i need to check my code.
This error occurs only on this repo, which contains a Rust workspace separate in two folders: one Tauri/Rust project and one basic Rust project.
Cargo.toml at the root:
[workspace]
members = [
"builder",
"studio/src-tauri"
]

I tried to uninstall and re-install Rust-Analyzer, switch to pre-release or older version, delete my target folder, run a cargo clean cmd but nothing changed, and I can't find any solution.

I had a similar issue while using rocket. Same error message too, Error: Pear requires a 'dev' or 'nightly' version of rustc.
If you get to the get-started page on rocket framework website. It says, "Rocket makes abundant use of Rust's syntax extensions and other advanced, unstable features. Because of this, we'll need to use a nightly version of Rust."
My issue was I was not using a nightly version of rust. Running this on my terminal in my project directory did it for me.
rustup override set nightly
If you check the cargo version for that directory after,
cargo version
you will confirm it has switched to nightly version
Failed compilation even with nightly
It looks like you have some outdated dependencies (pear-codegen probably being the one that causes trouble), updating these may resolve the compilation issues.
General notes on how to override the toolchain
Using rustups override works fine, but it is bound to your local rustup configuration and not specified inside the project.
In order to achieve this, thereby making the project more portable and allowing others to always use the correct toolchain, I would recommend the toolchain file. It can look something like this (example taken from linked page) and will accurately specify the required toolchain only for the containing project.
# rust-toolchain.toml
[toolchain]
channel = "nightly-2020-07-10"
components = [ "rustfmt", "rustc-dev" ]
targets = [ "wasm32-unknown-unknown", "thumbv2-none-eabi" ]
profile = "minimal"
For your purposes a simple configuration like this will most likely be all you need, although adding the components you want to use would be beneficial.
[toolchain]
channel = "nightly"
My issue was with rust-analyser that wouldn't start because multiple rocket dependencies needed nightly or dev version of rustc.
These steps fixed my issue:
Switch to nightly for my rocket project by running rustup override set nightly inside the app folder.
Remove all target folders in my project. (I also had one in root)
Manually remove the faulty cached packages from cargo cache. cd ~/.cargo/registry/cache/github.com-xxxxxxxxxxxx && rm -r pear_codegen-0.1.5/
I am trying to use bevy game engine with rust on windows. I have x86_64-mingw installed on my machine.
I have setup the rust tool chain default to x86_64-pc-windows-gnu. I put bevy = "0.4.0" under my dependencies in the Cargo.toml.
I tried cargo build and I get the following error
error: failed to run custom build command for `syn v1.0.63`

Edit:
My Antivirus was preventing it, and denying it access, so just turning my AV for sometime worked!
I've tried compiling a project that uses bevy = "0.4.0" and was able to build with the stable-x86_64-pc-windows-msvc toolchain but not with stable-x86_64-pc-windows-gnu.
In my case, bevy-glsl-to-spirv is the crate that failed to build. On the bevy book is specified that you must have VS build tools 2019 installed. They do not explicitly say that you must use the msvc toolchain but as they require you to install VS build tools 2019 I guess you must compile the code using stable-x86_64-pc-windows-msvc.
You can download VS build tools 2019 here.
Also make sure that you install the stable-x86_64-pc-windows-msvc toolchain:
rustup toolchain install stable-x86_64-pc-windows-msvc
Set this toolchain as the default toolchain.
rustup default stable-x86_64-pc-windows-msvc
Finally, make sure the toolchain has been installed and set as the default toolchain:
rustup toolchain list
You should see:
stable-x86_64-pc-windows-gnu
stable-x86_64-pc-windows-msvc (default)
Try to cargo build and it should work like a charm.
I have a basic rust/cargo project with a single main file and some basic dependencies. The cargo build command works fine when the target is not specified (I am using windows so it builds to windows), but when I try to cross compile the program to linux using cargo build --target=x86_64-unknown-linux-gnu or cargo build --target=x86_64-unknown-linux-musl, the process fails with the following error: linker 'cc' not found.
Does anyone have an idea how to get around this? Is there a specific linker I need to install?
Thanks.
I've just figured it out.
It turns out you need to tell cargo to use the LLVM linker instead. You do this by creating a new directory called .cargo in your base directory, and then a new file called config.toml in this directory. Here you can add the lines:
[target.x86_64-unknown-linux-musl]
rustflags = ["-C", "linker-flavor=ld.lld"]
Then building with the command cargo build --target=x86_64-unknown-linux-musl should work!
