MJSplitterのインストール

job

MJSplitterとは、Zope上で動作するプロダクトで、コンテンツを日本語の単語にぶった切ってインデックスを作成してくれるものです。ぶった切りにはMeCabを使用しています。今回の話は結構やっつけなので参考にしないほうがいいかも。

$INSTANCE/Product以下にMJSplitterのリンクを張って、インスタンスを起動するとこんなエラーがでました。環境はVine Linuxです。

$ ./runzope

なんでしょう。windllが定義されてないよって。
該当箇所のソースはこんな感じ。

def libmap(lib_path, func_catalogue, lib_type="cdll"):
    """Performs restype/argtypes mapping for each function in catalogue.
    """
    lib_type_map = {"cdll": cdll, "windll": windll, "oledll": oledll}
    lib = lib_type_map[lib_type].LoadLibrary(lib_path)
    for func_name, res_type, arg_types in func_catalogue:
        funcbody = getattr(lib, func_name)
        if res_type:
            funcbody.restype = res_type
        if arg_types:
            funcbody.argtypes = arg_types
    return lib

ただディクショナリを定義しているだけに見えるんだけどな。ま、定義がないって言うんだから消しちゃえ。ということでこうします。

def libmap(lib_path, func_catalogue, lib_type="cdll"):
    """Performs restype/argtypes mapping for each function in catalogue.
    """
    lib_type_map = {"cdll": cdll}
    lib = lib_type_map[lib_type].LoadLibrary(lib_path)
    for func_name, res_type, arg_types in func_catalogue:
        funcbody = getattr(lib, func_name)
        if res_type:
            funcbody.restype = res_type
        if arg_types:
            funcbody.argtypes = arg_types
    return lib

ちなみにoleddlを残すとそれもundefinedだって言われます。
これでZopeを再起動。

$ ./runzope

OSError: c:/Program Files/mecab/bin/libmecab.dll: cannot open shared object file: No such file or directory

こんどはファイルがないって言われます。
そりゃ、"c:/Program..."なんてWindowsみたいなファイルはないよね。この定義はsettings.pyにあります。

# location of mecab dynamic library
# setting for mecablib
MECAB_LIBPATH = 'c:/Program Files/mecab/bin/libmecab.dll'

これをこう変えます。

# location of mecab dynamic library
# setting for mecablib
MECAB_LIBPATH = '/usr/local/lib/libmecab.so'

mecabのライブラリファイルの位置は適時変更してください。
Zopeを再々起動。

ちゃんと起動しました。Splitがちゃんと動作してるかって？それはこれからですよ。
