GDAL RPM Build with Brunsli Support

This project provides a Dockerfile and RPM spec file to build GDAL from source with Brunsli compression support.

Overview

This project simplifies the process of building GDAL with Brunsli support by:

• Dockerized Build: Using a Docker image to provide a consistent and isolated build environment.
• RPM Packaging: Creating an RPM package for distribution and installation on RPM-based systems.
• Brunsli Integration: Including the necessary steps to build and integrate Brunsli into the GDAL build process.

Prerequisites

• Docker: Make sure you have Docker installed and running on your system.
• Git: Git is required to clone the Brunsli source code.

Build Instructions

git clone
cd gdal-brunsli-rpm
docker build -t gdal-builder .
docker run -it -v $(pwd)/output:/output gdal-builder

RPM Installation

sudo dnf install /path/to/gdal-3.6.4-1.el9.x86_64.rpm

Verification

Run gdalinfo --version

Brunsli Support

gdal_translate -of JPEG2000 -co QUALITY=50 input.tif output.jp2 #Brunsli Support
Compare the file size of output.jp2 with a JPEG2000 file generated without Brunsli. The Brunsli-compressed file should be 22% smaller.

Customization

*GDAL Version: Change the GDAL_VERSION argument in the Dockerfile to build a different version of GDAL.
*Dependencies: Adjust the dnf install commands in the Dockerfile to install any additional dependencies required for your specific needs.
*CMake Options: Modify the CMake options in the %build section of the gdal.spec file to customize the GDAL build.
*Output Directory: Change the volume mount in the docker run command to specify a different output directory for the RPM package.
