Pre-builds

Build

1. Linux/macOS

install GNU Autotools, then:

# build libmill
curl -s -L https://github.com/sustrik/libmill/archive/master.tar.gz | tar -zxf -
mv libmill-master libmill
cd libmill
./autogen.sh
./configure --enable-shared=false --enable-static
make
cd ../

# build libsodium
curl -s -L https://github.com/jedisct1/libsodium/archive/master.tar.gz | tar -zxf -
mv libsodium-master libsodium
cd libsodium
./autogen.sh
./configure --enable-shared=false --enable-static
make
cd ../

# build lz4
curl -s -L https://github.com/lz4/lz4/archive/master.tar.gz | tar -zxf -
mv lz4-master lz4
cd lz4
make -C lib
cd ../

# build muon
autoreconf -if
export CPPFLAGS="-I$(pwd)/lz4/lib -I$(pwd)/libmill -I$(pwd)/libsodium/src/libsodium/include"
export LDFLAGS="-L$(pwd)/lz4/lib -L$(pwd)/libmill/.libs -L$(pwd)/libsodium/src/libsodium/.libs"
./configure --prefix=/usr --sysconfdir=/etc --enable-static
make
make check
sudo make install

on macOS, install via Homebrew is also supported:

brew install --HEAD libmill
brew install libsodium lz4
brew install --HEAD https://raw.githubusercontent.com/puxxustc/muon/master/contrib/homebrew/muon.rb

2. Cross compile

# setup cross compile tool chain:
export PATH="$PATH:/pato/to/cross/compile/toolchain/bin/"

# build libmill
curl -s -L https://github.com/sustrik/libmill/archive/master.tar.gz | tar -zxf -
mv libmill-master libmill
cd libmill
./autogen.sh
./configure --enable-shared=false --enable-static --host=arm-unknown-linux-gnueabihf
make
cd ../

# build libsodium
curl -s -L https://github.com/jedisct1/libsodium/archive/master.tar.gz | tar -zxf -
mv libsodium-master libsodium
cd libsodium
./autogen.sh
./configure --enable-shared=false --enable-static --host=arm-unknown-linux-gnueabihf
make
cd ../

# build lz4
curl -s -L https://github.com/lz4/lz4/archive/master.tar.gz | tar -zxf -
mv lz4-master lz4
cd lz4
CC=arm-unknown-linux-gnueabihf-gcc make -C lib
cd ../

# build muon
autoreconf -if
export CPPFLAGS="-I$(pwd)/lz4/lib -I$(pwd)/libmill -I$(pwd)/libsodium/src/libsodium/include"
export LDFLAGS="-L$(pwd)/lz4/lib -L$(pwd)/libmill/.libs -L$(pwd)/libsodium/src/libsodium/.libs"
./configure --host=arm-unknown-linux-gnueabihf \
    --prefix=/usr --sysconfdir=/etc --enable-static
make
