私は Python の初心者で、http://blog.perrygeo.net/2008/04/19/a-quick-cython-introduction/ にある簡単な例で Cython を いじって みます。cython ファイルの名前は c1 です。 .pyx

それから実行cython c1.pyxして、大丈夫でした。それから実行してgcc -c -fPIC -I/usr/include/python2.7/ c1.c、それも大丈夫でした。しかし、実行するgcc -shared c1.o -o c1.soと、うまくいきませんでした。

誰でもこれに光を当てることができますか？

-lpython2.7リンカーのコマンドラインに (または使用している Python の任意のバージョン)を含める必要があります。

ただし、Cython を使用する最も簡単な方法は、distutils セットアップ スクリプトを使用することです。これにより、すべての重要なコンパイラ コマンドが実行されます。
