Build script for Fedora with ROCm/CUDA/CPU support

[JumpLink]

I created a build script for Fedora that supports building with ROCm (AMD GPU), CUDA (NVIDIA GPU), or CPU-only acceleration. This might be helpful for other users who want to build the project on Fedora or use it as inspiration for other Linux distributions with ROCm or CUDA support.

Prerequisites

• Fedora (tested on Fedora 41)
• For ROCm support: AMD GPU with ROCm support
• For CUDA support: NVIDIA GPU with CUDA support
• Applied changes from PR cmake qt and libdir build fixes #190 and followed instructions in issue [ERROR] Build error: (cmake) "set_property can not be used on an ALIAS target" - and clone fails in step 2 #197

I myself have only tested ROCm and it seems to work. CUDA would have to be tried by someone else and could give feedback here.

Usage

1. Save this script as build-fedora.sh in the project root
2. Make it executable: chmod +x build-fedora.sh
3. Run it: ./build-fedora.sh

#!/bin/bash

# Create build directory
rm -rf build
mkdir -p build

# Set acceleration to hipblas (AMD ROCm)
# Note: This seems to be needed only for the Windows builds, but I added it anyway as a precaution.
# Possible values for ACCELERATION:
# - "cpu"     : CPU only, no hardware acceleration
# - "cuda"    : NVIDIA GPU acceleration using CUDA
# - "hipblas" : AMD GPU acceleration using ROCm/HipBLAS
export ACCELERATION="hipblas"

# Configure with CMake
# For different hardware acceleration support, use WHISPER_ADDITIONAL_CMAKE_ARGS:
# CPU only:
#   -DWHISPER_ADDITIONAL_CMAKE_ARGS="-DWHISPER_BLAS=OFF -DWHISPER_CUBLAS=OFF -DWHISPER_OPENBLAS=OFF"
# AMD GPU (ROCm/HipBLAS):
#   -DWHISPER_ADDITIONAL_CMAKE_ARGS="-DWHISPER_BLAS=ON -DWHISPER_HIPBLAS=ON -DWHISPER_OPENBLAS=OFF -DWHISPER_CUBLAS=OFF"

echo "Build and installation completed!"

Notes

• The script includes support for ROCm, CUDA, and CPU-only builds through CMake options
• It automatically installs all required dependencies via dnf
• Creates backups of existing installations before overwriting
• Includes retry logic for build failures (specifically, the git checkouts often fail for me)
• Comments explain how to configure for different acceleration methods

Disclaimer

This script was created with the help of an AI assistant. While it works for my setup, I don't have deep understanding of the entire codebase. I'm sharing it in hopes it might help other users or serve as a starting point for automated builds on other distributions.

Feel free to improve upon this or incorporate parts of it into the official build system!
