#### Prepare Environment
Refer: https://help.synology.com/developer-guide/getting_started/prepare_environment.html
Assume `platform=geminilake`, `version=7.1`, working directory is `/synology-toolkit`
Now the build env is `/synology-toolkit/build_env/ds.geminilake-7.1`
#### Enter chrooot
``` ```
sudo chroot /synology-toolkit/build_env/ds.geminilake-7.1 sudo chroot /synology-toolkit/build_env/ds.geminilake-7.1
``` ```
### 3. Build module #### Clone source code
```
cd /usr/src/
git clone https://github.com/jim3ma/synology-igc.git
```
### 2. Build module
```shell ```shell
cd /usr/src/synology-igc/ cd /usr/src/synology-igc/
make -C /usr/local/x86_64-pc-linux-gnu/x86_64-pc-linux-gnu/sys-root/usr/lib/modules/DSM-7.1/build M=$PWD modules make -C /usr/local/x86_64-pc-linux-gnu/x86_64-pc-linux-gnu/sys-root/usr/lib/modules/DSM-7.1/build M=$PWD modules
