*初期設定 [#v1547697]
**OS [#la9f4428]
-[[ROCK64 Main Page - PINE64>http://wiki.pine64.org/index.php/ROCK64_Main_Page]]に一覧がある
-いくつかLinuxを試して、Community Build Debian Stretchを試すことにした。
-gccが6.3(!)
**gparted [#u7689d12]
-イメージが2GBなものなので、gpartedを使って拡張
-最後のパーティションが/で、その後ろが未使用領域。それを最大限拡張
**インストール [#gfec82fd]
-本当にminimalしか入ってないので、aptで必要パッケージをインストール
 $ sudo apt-get install cmake build-essential debconf libgtk2.0-dev openjdk-8-jre-headless strace less file
-ついでにOpenCVのビデオ用に、gstreamerをインストール
 $ sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad
**Time zoneの変更 [#qa38f9f9]
-dpkg-reconfigureコマンドは前述のdebconfパッケージに含まれる
 $ sudo dpkg-reconfigure tzdata
**gitのconfig [#y8dedbc1]
-名前とメールアドレス
 $ git config --global user.name "Foo Bar"
 $ git config --global user.email foo@bar.com
**SSH鍵の生成 [#h2986a5d]
-とりあえずecdsa型で鍵を生成
 $ ssh-keygen -t ecdsa
 $ ssh-keygen -f hoge
 $ cat hoge.pub >> .ssh/authorized_keys
**OpenCVのclone [#a6243d24]
