Subject: [ruby-list:10175] VPATH

SRA の笠原です。

Ruby-1.1c6 のソースコードの Makefile.in を見ると、$(srcdir) や VPATH
といった単語が入っているので、ソースコードとは別のディレクトリでコンパ
イルすることも考慮しているような気配なのですが、実際にやってみると幾つ
かのファイルが見つけらないために、途中でコンパイルエラーを起こしてしま
います。

そこで、別のディレクトリでもコンパイルできるようにするためのパッチを作っ
てみましたので、添付します。採用して頂けると嬉しいです。

それから蛇足ですが、gperf は AC_PATH_PROG (or AC_PATH_PROGS) でチェッ
クした方が良いと思います。
