So I set up GTK-rs for rust and I must have done something wrong because when I try to run my code it returns this error and I have no idea how to fix it:
fatal error LNK1181: cannot open input file 'gtk-3.lib'
I use Eclipse IDE if that will help.
Some more data that might help:
My environment variables are:
GTK_LIB_DIR=C:\msys64\mingw64\lib
PATH:
C:\msys64\mingw64\bin
C:\msys64\mingw64\include
My Cargo.toml file:
[package]
name = "myapp"
version = "0.1.0"
authors = ["author"]
edition = "2018"
[dependencies.gtk]
version = "0.9.2"
features = ["v3_16"]
[dependencies]
glib = "0.10.2"
gio = "0.9.1"
I used some modified sample code for testing:
#![allow(non_snake_case)]
extern crate gtk;
extern crate glib;
extern crate gio;
use gio::prelude::*;
use glib::clone;
use gtk::prelude::*;
// When the application is launched…
fn on_activate(application: >k::Application) {
// … create a new window …
let window = gtk::ApplicationWindow::new(application);
// … with a button in it …
let button = gtk::Button::with_label("Hello World!");
// … which closes the window when clicked
button.connect_clicked(clone!(#weak window => move |_| window.close()));
window.add(&button);
window.show_all();
}
fn main() {
// Create a new application
let app = gtk::Application::new(Some("com.github.gtk-rs.examples.basic"), Default::default())
.expect("Initialization failed...");
app.connect_activate(|app| on_activate(app));
// Run the application
app.run(&std::env::args().collect::<Vec<_>>());
}
I was having the same problem with "link.exe" when using gstreamer and gtk Rust bindings. Here's what I did to make my program compile.
Download Microsoft Build Tools and install the following in addition to the 'default' tools that are installed when checking the "C++ build tools".
MS Build Tools Options - credit https://github.com/rust-lang/rust/issues/44787
After the installation, make sure that "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC<VC Version>\bin\Hostx64\x64" is in your environment path.
Restart your pc and try compiling again. Hopefully it is going to work. However, if it still doesn't, I recommend uninstalling Rust from powershell
rustup self uninstall
And then reinstalling Rust from the rustup.exe in this way.
Run rustup.exe
When prompted with the install option, select "customize installation"
For default host triples option type
stable-x86_64-pc-windows-gnu
Press enter for 'default' options for the rest and continue installation.
Restart your pc and the program is definitely going to compile.

I'm new to rust. I'm following a getting started tutorial that imports the crate random-number but when running the code I'm getting the error can't find crate for 'random_number'. What am I doing wrong?
~/Cargo.toml:
[package]
name = "test"
version = "0.0.1"
edition = "2021"
[dependencies]
random-number = "0.1.8"
~/src/main.rs:
extern crate random_number;
use random_number::random;
fn main() {
let num: i8 = random!(..);
println!("{}", num);
}
rustc is not meant to be used directly. It is the compiler that can compile a .rs file, but it doesn't have any dependency manager attached to it. So if you decide to use rustc directly, you need to manage your dependencies manually.
cargo is the official tool to compile Rust projects. It internally uses rustc, but additionally manages the project's dependencies that are specified in Cargo.toml.
cargo build --release && ./target/release/<project_name>
or the short form:
cargo run --release
I'm using the epub crate on version 1.2.3 and my Cargo.toml is formatted as such
[package]
name = "cl-epub-reader"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
epub = "1.2.22"
and my main.rs is
use epub::doc::EpubDoc;
use epub::doc::NavPoint;
use std::env::args;
fn main() {
let args: Vec<String> = args().collect();
let doc = EpubDoc::new(&args[1]).unwrap();
// assert!(doc.is_ok());
println!("{:?}", doc.mdata("title"));
}
All it does is get the uses the path from the a user input then it gets the title metadata and printing it.
When I run cargo run it outputs an error about an error about going out of range, which is expected however when I run rustc src/main.rs the error is error[E0433]: failed to resolve: maybe a missing crate `epub`?
Does anyone know the cause of this and how to solve this issue?
When you call rustc directly, you need to pass the appropriate options to tell the compiler where the crates are installed on your computer. cargo handles that automatically for you (you can use the -v option to cargo build to see the actual rustc command lines it uses).
I have a simple Gtk app in Rust, but I get this error when compiling:
Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' found
And yes, I read Cannot compile gstreamer on Windows because it is missing glib-2.0, but it still doesn't contain all the information I need.
I put export PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig/ in /home/user/.profile (as shown in Can't Set Environment Variables in ~/.profile), and I also ran it directly in the Rust project directory, to no avail. I used that path because it seemed closest to the one in the Windows question, though there were many pkgconfig directories on the system, in various places.
Here is my Rust code:
use gtk::prelude::*;
use gtk::{Application, ApplicationWindow};
fn main() {
let app = Application::builder()
.application_id("org.example.HelloWorld")
.build();
app.connect_activate(|app| {
// We create the main window.
let window = ApplicationWindow::builder()
.application(app)
.default_width(320)
.default_height(200)
.title("Hello, World!")
.build();
// Show the window.
window.show();
});
app.run();
}
and here is Cargo.toml:
[package]
name = "gtk_test"
version = "0.1.0"
edition = "2018"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
gtk = { version = "0.2", package = "gtk4" }
So my question: where is the glib-2.0.pc file on a Linux? Is it under a different name, or does it have to be installed?
I've had the same issue on Fedora 36 ARM. I've installed libwebkitgtk, rust-gtk-sys-devel, libproxy-webkitgtk4, webkitgtk4, libsoup, libsoup-devel and webkitgtk4-devel and it started working. Some of libraries above may not be needed for your issue. For fedora the command is:
sudo dnf install libwebkitgtk rust-gtk-sys-devel libproxy-webkitgtk4 webkitgtk4 libsoup libsoup-devel webkitgtk4-devel
I try to compile my project with the command cargo build.
build.rs
extern crate csv;
use std::path::Path;
use std::fs::OpenOptions;
use std::io::BufWriter;
use std::io::Write;
#[allow(non_snake_case)]
fn processCSV(filename: &str, sourcePath: &str, enumName: &str) {
println!("Generate rust source code from schema {}",filename);
let mut ret: Vec<String> = Vec::new();
let mut rdr = csv::Reader::from_file(filename).unwrap().flexible(true);
for record in rdr.records().map(|r| r.unwrap()) {
}
let path = Path::new(sourcePath);
let file = match OpenOptions::new().write(true).create(true).open(&path) {
Ok(file) => file,
Err(..) => panic!("Cannot create file {}",path.display()),
};
let mut writer = BufWriter::new(file);
writer.write_all(b"test\n");
}
fn main() {
processCSV("../schemas/Test.csv", "./src/mod/common/StatusCode.rs", "StatusCode");
}
and Cargo.toml
[package]
name = "rust-test"
version = "0.0.1"
build = "build.rs"
[lib]
path = "src/lib.rs"
[dependencies]
[build-dependencies]
csv = "*"
I can see this error :
src/lib.rs:1:1: 1:18 error: can't find crate for csv
src/lib.rs:1 extern crate csv;
but when I change flexible(true) to flexible(false) it compiles just fine without any errors. What do I need to do to fix this?
I am using Rust 1.2.0 on Windows 7 64-bit.
Changing flexible(false) for flexible(true) makes no difference for me; both fail. The problem is that you've chosen build-dependencies for some reason, instead of just dependencies.
Using the src/lib.rs file that you provided in your answer, and this Cargo.toml file:
[package]
name = "stack-overflow"
version = "0.1.0"
authors = ["A. Developer <a.developer#example.com>"]
[dependencies]
csv = "*"
It compiles fine.
If you need to access a dependency both in your build.rs and in your project, you need to include the dependency in both sections.
A build dependency is a dependency for a build script, which is a helper binary compiled and run before your main crate is built (designed to be used for code-generation, and building/finding native C libraries, etc.).
Normal dependencies used by the main code should just fall into the "dependencies" section, e.g.
[dependencies]
csv = "0.14"
There's also a "dev-dependencies" section, which are dependencies that are only needed for testing, i.e. they are compiled and used only for cargo test. This allows crates to depend on, for example, quickcheck for running tests without contaminating the main artifact.
In summary, running cargo build will do something like:
build any build-dependencies
build the build script (pointing the compiler to the built build-dependencies), and run it
build any dependencies
build the main crate (pointing the compiler to the built dependencies)
Running cargo test adds:
build any dev-dependencies
build the main crate with --test to create a test runner for any in-source #[test]s (pointing the compiler to both the dependencies and dev-dependencies)
build any external examples or tests, also pointing to both the dependencies and dev-dependencies
I wrote a program to parse some filenames in Rust using the standard Regex crate. The program runs fine on Linux, but when I tried to compile and run it on Windows, I get some kind of DLL error. I don't really understand what is going on with this, but it's all I have to go on.
This is the compiler version that I'm using:
F:\Coding\rust-shutterstock-deduper\target (master)
λ rustc --version
rustc 1.0.0-nightly (3ef8ff1f8 2015-02-12 00:38:24 +0000)
This is the program that I'm trying to run:
#![feature(plugin)]
#![plugin(regex_macros)]
extern crate regex_macros;
extern crate regex;
fn main() {
let x = regex!(".*");
}
And my Cargo.toml file:
[package]
name = "my_package"
version = "0.0.1"
authors = ["Nate Mara <natemara#gmail.com>"]
[dependencies]
regex = "0.1.14"
regex_macros = "0.1.8"
Are there compiler flags that I should be passing in, or do I need to run this in a special way, or... what am I doing wrong here? I'm just running with cargo run
Add #[no_link] to your code:
#![plugin(regex_macros)]
#[no_link]
extern crate regex_macros;
Right now, plugins are crates, which means they get linked in. The regex_macros crate should tell you to add no_link, but this is a temporary workaround for a Rust issue. However, it looks like this is in the process of being fixed.
