# RPi Patches
|
|
|
|
This directory contains patches for dependencies that need modifications to build on ARM64.
|
|
|
|
## Current Status (v4.2+)
|
|
|
|
As of Stegasoo 4.2, we use **jpeglib** instead of jpegio. The jpeglib build process is handled inline in `setup.sh` and includes:
|
|
|
|
- Cloning from GitHub (PyPI tarball missing headers)
|
|
- Downloading libjpeg headers for each version (6b through 9f)
|
|
- Patching setup.py to skip turbo/mozjpeg (need cmake-generated headers)
|
|
|
|
See `setup.sh` for the full implementation.
|
|
|
|
## Legacy: jpegio Patches (v4.1 and earlier)
|
|
|
|
The `jpegio/` directory contains patches for the old jpegio dependency, which required removing x86-specific `-m64` compiler flags. These are no longer used but kept for reference.
|
|
|
|
## jpeglib Helper Script
|
|
|
|
The `jpeglib/install-jpeglib-arm64.sh` script is a standalone version of the jpeglib build process. It's not used by setup.sh (which has the logic inline) but can be useful for manual testing or debugging.
|
|
|
|
## Structure
|
|
|
|
```
|
|
patches/
|
|
jpegio/ # Legacy (v4.1) - not used in v4.2+
|
|
arm64.patch
|
|
apply-patch.sh
|
|
jpeglib/ # Reference script for manual builds
|
|
install-jpeglib-arm64.sh
|
|
```
|
|
|
|
## Adding New Patches
|
|
|
|
If a new dependency needs ARM64 patches:
|
|
|
|
1. Create a directory: `patches/<package>/`
|
|
2. Add patch files or helper scripts
|
|
3. Update `setup.sh` to apply the patch during installation
