fix_libtool_files.sh

Gentoo Linuxでいつものように、

# emerge -Duvt --newuse world
# emerge -Duv --newuse world

なんてことをしていたら

とgtk+のコンパイルで失敗するようになってしまい、たしかにちょいと前にgccが3.3.5になったからお探しの「/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.4/libstdc++.la」なんてものは見つからないわけだけど、「libtool: link: 〜」ってあるから、

# emerge libtool

で再度libtoolをインストールしてみたのだけどダメ。もしやと思い、

# env-update && source /etc/profile

なんてこともしたが意味なし。ここでようやくWebで検索してみたところ、

にあるドイツなGentooフォーラムのイッヒやグーテンやモルゲンの森の中に「fix_libtool_files.sh」というファイル名を発見。

# fix_libtool_files.sh 
Usage: fix_libtool_files.sh  [--oldarch ]

    Where  is the version number of the
    previous gcc version.  For example, if you updated to
    gcc-3.2.1, and you had gcc-3.2 installed, run:

      # fix_libtool_files.sh 3.2

    If you updated to gcc-3.2.3, and the old CHOST was i586-pc-linux-gnu
    but you now have CHOST as i686-pc-linux-gnu, run:

      # fix_libtool_files.sh 3.2 --oldarch i586-pc-linux-gnu

    Note that if only the CHOST and not the version changed, you can run
    it with the current version and the '--oldarch ' arguments,
    and it will do the expected:

      # fix_libtool_files.sh `gcc -dumpversion` --oldarch i586-pc-linux-gnu


# fix_libtool_files.sh 3.3.4
