## Development

- Assumed that we are using `ubuntu-16.04` and `crystal-0.22.x`.

Please install `libxml2.a` first as bellow.

```shell
make
```

### static libxml2.a

We can't link statically against libxml2 due to lack of `ICU_XXX` in `ubuntu-16.04`.
So we manually build `libxml2.a` without icu first.

```
apt-get install automake # for `aclocal`
apt-get install liblzma-dev
apt-get install python2.7-dev
apt-get source libxml2
cd libxml2-2.9.3+dfsg1
./configure --with-python=no --with-trio=no --with-http=no --with-ftp=no
make

sudo mv /usr/lib/x86_64-linux-gnu/libxml2.a{,.dist}
sudo cp -p .libs/libxml2.a /usr/lib/x86_64-linux-gnu/
```
