by ADMIN 48 views

Introduction

Compiling and running Doom can be a thrilling experience, but it can also be frustrating when it doesn't work as expected. In this article, we'll explore the issue of Doom crashing on startup with the error message "Resource temporarily unavailable" and provide a step-by-step guide to resolve the problem.

System Configuration

Before we dive into the solution, let's take a look at the system configuration that was used to compile and run Doom:

  • rust-doom: 6aa7681cee4e181a2b13ecc9acfa3fcaa2df4014
  • rustc: rustc 1.85.0 (4d91de4e4 2025-02-17) (Fedora 1.85.0-1.fc41)
  • OS: Fedora Linux 41
  • Cargo: cargo 1.85.0 (d73d2caf9 2024-12-31)

Error Message

The error message that was encountered is:

[INFO  engine::context] Creating system "tick"...
[INFO  engine::context] Creating system "frame_timers"...
[INFO  engine::context] Creating system "window"...
interface 'wl_output' has no event 4

thread 'main' panicked at /home/roland/.cargo/registry/src/index.crates.io-1949cf8b6b5b557f/winit-0.21.0/src/platform_impl/linux/wayland/event_loop.rs:395:10:
called `Result::unwrap()` on an `Err` value: Os { code: 11, kind: WouldBlock, message: "Resource temporarily unavailable" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Understanding the Error Message

The error message indicates that there is a problem with the Wayland event loop, which is responsible for handling events such as keyboard and mouse input. The specific error message "Resource temporarily unavailable" suggests that the system is unable to allocate the necessary resources to run the event loop.

Possible Causes

There are several possible causes for this error:

  • Insufficient system resources: The system may not have enough resources (e.g., memory, CPU) to run the event loop.
  • Conflicting dependencies: There may be conflicting dependencies between the Doom engine and other libraries or frameworks that are installed on the system.
  • Incorrect configuration: The configuration of the system or the Doom engine may be incorrect, leading to the error.

Resolving the Issue

To resolve the issue, we'll try the following steps:

Step 1: Check System Resources

First, let's check if the system has sufficient resources to run the event loop. We can use the top command to check the system's memory and CPU usage:

top

If the system is running low on resources, we may need to close some applications or restart the system.

Step 2: Update Dependencies

Next, let's update the dependencies of the Doom engine to ensure that we have the latest versions of the libraries and frameworks:

cargo update

Step 3: Reconfigure the System

If the issue persists, we may need to reconfigure the system or the Doom engine to resolve the conflict. We can try setting the RUST_BACKTRACE environment variable to display a backtrace:

export RUST_BACKTRACE=1

Step 4: Rebuild and Reinstall Doom

Finally, let's rebuild and reinstall the Doom engine to ensure that we have the latest version of the engine:

cargo build
cargo install

Conclusion

In this article, we explored the issue of Doom crashing on startup with the error message "Resource temporarily unavailable" and provided a step-by-step guide to resolve the problem. By checking system resources, updating dependencies, reconfiguring the system, and rebuilding and reinstalling the Doom engine, we should be able to resolve the issue and run Doom successfully.

Additional Tips

  • Make sure that you have the latest version of the Rust compiler and the Cargo package manager installed.
  • Check the system's logs for any error messages that may indicate the cause of the issue.
  • If the issue persists, try seeking help from the Doom community or the Rust community for further assistance.

Q: What causes the "Resource temporarily unavailable" error?

A: The "Resource temporarily unavailable" error is caused by a problem with the Wayland event loop, which is responsible for handling events such as keyboard and mouse input. This error can be caused by insufficient system resources, conflicting dependencies, or incorrect configuration.

Q: How can I check if my system has sufficient resources to run the event loop?

A: You can use the top command to check the system's memory and CPU usage. If the system is running low on resources, you may need to close some applications or restart the system.

Q: What are the possible causes of the "Resource temporarily unavailable" error?

A: The possible causes of the "Resource temporarily unavailable" error include:

  • Insufficient system resources
  • Conflicting dependencies
  • Incorrect configuration

Q: How can I update the dependencies of the Doom engine?

A: You can update the dependencies of the Doom engine by running the following command:

cargo update

Q: What is the purpose of setting the RUST_BACKTRACE environment variable?

A: Setting the RUST_BACKTRACE environment variable allows you to display a backtrace when the program crashes. This can help you diagnose the cause of the issue.

Q: How can I rebuild and reinstall the Doom engine?

A: You can rebuild and reinstall the Doom engine by running the following commands:
