Compile

• Linux compile, Ubuntu machine for example:

sudo apt update -y && sudo apt install rename

# Native compilation
git clone https://github.com/gngpp/opengpt.git && cd opengpt
./build.sh

# Cross-platform compilation, relying on docker (if you can solve cross-platform compilation dependencies on your own)
./build_cross.sh # Default using docker build linux/windows platform 
os=macos ./build_cross.sh # The MacOS platform is built on MacOS by default

# Compile a single platform binary, take aarch64-unknown-linux-musl as an example: 
docker run --rm -it \
  -v $(pwd):/home/rust/src \
  -v $HOME/.cargo/registry:/root/.cargo/registry \
  -v $HOME/.cargo/git:/root/.cargo/git \
  ghcr.io/gngpp/opengpt-builder:x86_64-unknown-linux-musl \
  cargo build --release

• OpenWrt compile

cd package
svn co https://github.com/gngpp/opengpt/trunk/openwrt
cd -
make menuconfig # choose LUCI->Applications->luci-app-opengpt
