I have a clean project to which I include anyhow 1.0.66.
Installed the latest version of rust.
I'm getting an error saying that anyhow requires a nightly version. Perhaps this is due to the use of backtrace, but it is supported in rust version 1.65. I don't understand how to solve the problem.
Cargo.toml
[package]
name = "libfs"
version = "0.1.0"
edition = "2021"
[dependencies]
tokio = {version = "1.22", features = ["full"]}
anyhow = {version = "1.0.66", features = ["default"]}
src/lib.rs
#[tokio::test]
async fn run_test() {
println!("test");
}
output
$ cargo build

This seems to be related to dtolnay/anyhow/issues/250 and rust-lang/rust-analyzer/issues/12973.

I am trying to build the following program:
use x11::xfixes::XFixesHideCursor;
use x11::xlib::XDefaultRootWindow;
use x11::xlib::XOpenDisplay;
use x11::xlib::XSync;
fn main() {
let display;
let window;
unsafe {
display = XOpenDisplay(&0);
window = XDefaultRootWindow(display);
XFixesHideCursor(display, window);
XSync(display, 1);
}
}
Cargo.toml:
[package]
name = "xhidecursor"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

x11 = { version = "2.20.0", features = ["xlib"] }
Which fails with:

I already resolved a similar linking issue by including the x11 feature xlib in my Cargo.toml. However, the x11 crate does not seem to ship a feature for xfixes.
What is the correct way to also link to xfixes?
It turned out to be a bug in the x11 crate:
https://github.com/AltF02/x11-rs/issues/158
It was fixed upstream, but no release has been made yet.
I am trying to use GSL in Rust https://docs.rs/GSL/6.0.0/rgsl/ but am having trouble as I am very new to Rust. Every other crate I have tried to use just works by including the dependency in the Cargo.toml file. However, it doesn't seem to be this simple for this crate.
I have GSL installed and in Visual Studio 2022 I can successfully include it and I successfully built a program which uses functions from the library in C++.
#include <iostream>
#include <gsl/gsl_specfunc.h>
int main()
{
double k = 0.5;
double k_prime = sqrt(1 - k * k);
double K = gsl_sf_ellint_Kcomp(k, GSL_PREC_DOUBLE);
double K_prime = gsl_sf_ellint_Kcomp(k_prime, GSL_PREC_DOUBLE);
std::cout << K/K_prime << "\n";
}
I use IntelliJ as my Rust IDE, and I have a project with a Cargo.toml
[package]
name = "rust-gsl-test"
version = "0.1.0"
edition = "2021"
[dependencies]
GSL = "4.0"
In IntelliJ's terminal, when I type cargo build, I get
error: linking with `link.exe` failed: exit code: 1181

Should I rather select different version of tuntap crate or is there some different crate for managing tun/tap devices?
I'm attempting to get a working prototype of the following scenario:
Language: Rust (rustc 1.45.0-nightly (ad4bc3323 2020-06-01))
Framework: Rocket v0.4.4
Build Tool: Bazel
Platform: Mac OS X / Darwin x64
Running bazel build //web-api yields the below error. I believe, based on looking at the Cargo.lock file it is because Rocket's dependency on the hyper library specifies a dependency on the log 0.3.9 library. For whatever reason it is not using the more recent log=0.4.x. That said, I don't know why it's pulling this library since, if I build it manually, it works fine.

In order to set up the cargo-raze I did the following, following instructions from the github page.:
$ cd web-api/cargo
$ cargo generate-lockfile
$ cargo vendor --versioned-dirs --locked
$ cargo raze
(The generate-lockfile is what creates the Cargo.lock file, and the cargo raze is what creates the BUILD.bazel file and all the contents of the remote sub directory.)
And then to execute the bazel build I go back to the root and run bazel build //web-api, which produces the above error.
This is my WORKSPACE file:
workspace(name = "rocket-bazel")
load("#bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "io_bazel_rules_rust",
sha256 = "f21c67fc2fef9d57fa3c81fde1defd9e57d451883388c0a469ec1c470fd30dcb",

load("//web-api/cargo:crates.bzl", "raze_fetch_remote_crates")

This is my web-api/BUILD file:
load("#io_bazel_rules_rust//rust:rust.bzl", "rust_binary")
rust_binary(
name = "web-api",
srcs = ["src/main.rs"],
deps = [
"//web-api/cargo:rocket",
],
)
And my web-api/cargo/Cargo.toml file:
load("#io_bazel_rules_rust//rust:rust.bzl", "rust_binary")
rust_binary(
name = "web-api",
srcs = ["src/main.rs"],
deps = [
"//web-api/cargo:rocket",
],
)
I've run out of ideas as to what to try. I can get this to compile without Bazel, just using rust (though obviously the files are in slightly different places). I can get it to compile inside a Docker container. I just can't get Bazel (necessarily with cargo raze, either in vendor or remote mode) to run successfully: I assume that there is some mismatch in compile target or the nightly build that is not being properly set - but I'm not sure how to diagnose or get past that.
Here is a link to a repository with the files/structure I tried.
I had a similar issue when I made a minimal Bazel workspace with rust and the log crate together with env_logger crate. I found a similar issue when you try to compile without features = ["std"]. I then tried to enable that in Cargo.toml on the log dependency without success.
My solution is that in Cargo.toml under [raze] I added:
default_gen_buildrs = true
I could trace it down to that when default_gen_buildrs flag is not set in the generated log crate the BUILD.bazel file did not have a cargo_build_script definition or this:
crate_features = [
"std",
],
I'm unable to compile a basic example using Actix. I suspect I might be missing some libraries but I have no clue of what it could be. I also upgraded to Mojave a few days ago, but I'm not sure if this is related.
It seems to complain about ar crs and about an internal error happening in ranlib when running this command.
main.rs:
extern crate actix_web;
use actix_web::{server, App, HttpRequest};
fn index(_req: &HttpRequest) -> &'static str {
"Hello world!"
}
fn main() {
server::new(|| App::new().resource("/", |r| r.f(index)))
.bind("127.0.0.1:8088")
.unwrap()
.run();
}
Cargo.toml:
actix-web = "0.7.8"

The complete backtrace is too large to include on Stack Overflow.
It seems to work after installing cctools through MacPorts.
For some reason, installing it through brew didn't seem to work.
I had the same error.
When I replaced cctools 855 with 921 from this tap then cargo build worked: https://github.com/dgsga/homebrew-cctools
brew unlink cctools
brew tap dgsga/cctools
brew install dgsga/cctools/mtoc
