岡田先生　夜分遅くに失礼します。
03150289の中山です。
GCの課題を行おうと思いまして、変更したものをcatkin buildしてrosrunしたらpackageが存在しないと言われてしまいました。
20151007の課題を復習しようとした時も結局pacage beginner_tutorials not found となってしまったので根本的にどこかが変になってしまったと思うのですが全くわかりません。
ちなみにsource ~/2015-soft3/devel/setup.bashはしてあります。

おそくなりました．

[rospack] Error: package 'enshu_20141202' not found

が問題かな．
WORKSPACEのルートを~/work/win15/2015-soft3/20151202/src/enshu_20151202/においているか，
~/work/win15/2015-soft3/ においているか，どっちかなんだけど，
（WORKSPACEに対して，WORKSPACE/src, WORKSPACE/devel, WORKSPACE/buildができる）

上のログを見ると，~/work/win15/2015-soft3/ においてあるように見えるのですが，そこでcatkin buildしたら，enshu_20151202 が見つかっていないので，そこが問題に見えます．何が悪いかわからないけど，どこかにCATKIN_IGNOREとかのファイルがないだろうか，このファイルがあるとそれ以降のディレクトリを見てくれなくなります．可能性があるのは，~/work/win15/2015-soft3/20151202/CATKIN_IGNOREとかないだろうか．

現状``/work/win15/2015-soft3/にWORKSPACEがあるので，ちょっときたなくなるけど， /work/win15/2015-soft3/20151202` または，`~/work/win15/2015-soft3/20151202/src/enshu_20151202/`にWORKSPACEのルートとしてもよいです．その場合は
そのディレクトトリで`catkin init` してから`catkin build` すると`enshu_20151202`がコンパイルされると思います．後者にしたほうが他のディレクトリをコンパイルしないので，余計なトラブルはないかもしれないです．

今作業しているディレクトリでcatkin initしてからcatkin buildしたのですがやはり見つからないとなってしまいます。
WORKSPACEは確かに~/work/win15/2015-soft3/においていると思います。
CATKIN_IGNOREファイルも無いみたいなので他に可能性がありそうなことは無いでしょうか。

なるほど．

としてから同じ場所でcatkin buildするとどうなるでしょうか．

あ，ワークスペースをまちがいていたかもしれないです．

cd mech-user@test1-pc:~/work/win15/2015-soft3/20151202/
rm -fr src/enshu_20151202/.catkin*
catkin init -w .
catkin build

でしょうか．

出来ました！！
ありがとうございます。

workspaceを20151202にしたということでしょうか？
他のディレクトリで行う場合はまたそこをワークスペースにすれば良いということですか？

はいそうですね．

他のディレクトリで行う場合はまたそこをワークスペースにすれば良いということですか？

全てのディレクトリをまとめて一つのワークスペースにするか，それぞれのディレクトリでワークスペースにするか
方針を一つにして進めていけばいいと思います．今回は両方のルールが混ざっていてうまく行かなかったということか
ともいます．
