RapsberryPi 用 camera board のテストをするために、とりあえず webcamd を ports から入れてみたときの作業メモです。
個人的な感触ですが、RapsberryPi で ports をビルドしたい場合、RapsberryPi では ports tree の取得にかなり時間がかかるので、イメージを作る段階で併せて入れておく方が何かと便利です。
イメージ作成時に入れなかった場合は、svn で ports tree を取得するよりも、portsnap を使用する方が、ファイルが壊れるなどのトラブルが発生しにくい気がします。
portsnap を使用して、ports tree を取得する初回の手順は、以下の通りです。
# portsnap fetch
# portsnap extract
# cd /usr/ports
# make fetchindex
2回目以降は、こちらになります。
# cd /usr/ports
# portsnap fetch
# portsnap update
# make fetchindex
ここから、webcamd のビルドに移ります。
# cd /usr/ports/multimedia/webcamd/
# make config-recursive
# make install clean
これで何もエラーも起きずに最後までたどり着ければいいのですが、わたしは以下の3つの ports でエラー等が発生しましたので、わたしの行った回避方法を書きます。
(1) security/libgcrypt

回避方法: make.conf に MALLOC_PRODUCTION=yes が設定されていれば回避出来るエラーなのですが、問題は、このオプションが RaspberryPi のイメージ作成時に反映されていなければいけない、ということです。ですので、このエラーが発生した場合は、イメージ作成時の設定などを見直して、MALLOC_PRODUCTION=yes が有効になっているイメージを再作成し、かつ、RaspberryPi の make.conf にもオプション設定した上で glib20 を再コンパイルする必要があります。
（まあ、イメージを作りなおしたということは、そもそもの最初からやり直し、ではありますが・・。）
あと、この問題でビルドが止まるのは、このエラーが直接原因ではなく、他の ports で、必要なヘッダファイル(gio/gio.h 等)が入っていないという形で現れるので、注意が必要です。
コンパイルが完了したら、webcamd を動作させるために追加の設定が必要になります。
# echo 'cuse4bsd_load="YES"' >> /boot/loader.conf
# echo 'webcamd_enable="YES"' >> /etc/rc.conf
しかし、実は、xorg のコンパイルがまだ終わっていないので、動作確認ができていません。ほんとに動くんでしょうかね、これ・・。
