Wlvncc Build Failure

by ADMIN 21 views

Introduction

The Wlvncc build failure is a common issue encountered by developers when attempting to compile the Wlvncc project. This article provides a comprehensive guide to troubleshooting and resolving the Wlvncc build failure, including the error message, log analysis, and potential solutions.

Understanding the Error Message

The error message indicates that the builder for the Wlvncc project failed with exit code 1. The last 30 log lines provide valuable information about the build process, including the phases executed, the Meson build system version, and the host machine details.

Analyzing the Log

The log analysis reveals the following key points:

  • The build process executed the updateAutotoolsGnuConfigScriptsPhase and configurePhase phases.
  • The Meson build system version is 1.7.0.
  • The host machine is a 64-bit x86 architecture with GCC 14.2.1 as the C compiler.
  • The build process found the required libraries, including xkbcommon, pixman-1, wayland-client, wayland-cursor, and libdrm.
  • However, the build process failed to find the gbm library, which is a dependency of the Wlvncc project.

Potential Solutions

Based on the log analysis, the following potential solutions can be explored:

1. Install the gbm Library

The gbm library is a dependency of the Wlvncc project, and its absence is causing the build failure. To resolve this issue, install the gbm library on the host machine.

Installing gbm on NixOS

On NixOS, install the gbm library using the following command:

nix-env -i gbm

Installing gbm on Other Linux Distributions

On other Linux distributions, install the gbm library using the package manager. For example, on Ubuntu-based systems, use the following command:

sudo apt-get install libgbm1

2. Update the meson.build File

The meson.build file is the build configuration file for the Wlvncc project. Update this file to include the gbm library as a dependency.

Updating meson.build

Update the meson.build file to include the following line:

dependency('gbm')

This will instruct Meson to include the gbm library as a dependency during the build process.

3. Rebuild the Wlvncc Project

After updating the meson.build file, rebuild the Wlvncc project using the following command:

nix-build

This will rebuild the Wlvncc project with the updated meson.build file and the gbm library as a dependency.

Conclusion

The Wlvncc build failure is a common issue that can be resolved by installing the gbm library, updating the meson.build file, and rebuilding the project. By following the steps outlined in this article, developers can troubleshoot and resolve the Wlvncc build failure and successfully compile the project.
