Linux（CentOS 5.x）、PHP 5.1.6の環境において、PHP 拡張モジュールImagickをインストールする時にエラーとなってインストールが失敗することがある。その1つの例がPECLのバグだ。（今のところ、2つ目の例はまだ知らない・・・。）

まずは、「ImageMagick」、「ImageMagick-devel」をyumでインストールする。

[root@nobuneko lib]# yum install ImageMagick
[root@nobuneko lib]# yum install ImageMagick-devel

ここまでは順調。しかし、次で失敗。

さて、どうしようかなぁ、と思ってWebで探していたら、以下のページを発見。

http://pecl.php.net/bugs/bug.php?id=18057
[2010-08-12 14:46 UTC] mkoppanen at php dot net
This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.

Thank you for the report, and for helping us make PECL better.

This bug has been fixed in svn already. There hasn't been a release yet
but there will be one soonish.

どうやらPECLのバグのようだ。・・・そうですか。
とりあえず、上記のページの続きを読んでみる。

Any idea when CentOS 5.5 will see this bug fix in stable?
[2010-09-16 14:09 UTC] joris at timdm dot nl
Thank you for fixing the bug, but is there a workaround for?

r_nobu適当訳「バグを直してくれてありがとう、ところで、回避策ってない？」

《略》
The simplest workaround is to edit /usr/bin/php-config, find the
following lines:

--version)
echo $version;;

And add two more lines after them:

--vernum)
echo "50106";;

If that doesn't work, increase the "version number" of PHP until it does
:)

《r_nobu適当訳》
一番簡単な回避策は、/usr/bin/php-config（というファイル）を編集することだよ。

--version)
echo $version;;

って書いている行を見つけて、この行のすぐ下に次の2行を追記する。

--vernum)
echo "50106";;

もし、これでうまく動かない場合は、うまく動くようになるまで、PHPの「version number」（vernumのことだろう）の値を大きくしていけばよい（この何かいい加減な感じのアドバイスにちょっと笑ってしまった）。

私は、この「回避策」を使わせてもらうことにした。
おかげさまで、うまくいった！

Libraries have been installed in:
/var/tmp/pear-build-root/imagick-3.0.0/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

You should add "extension=imagick.so" to php.ini

php.iniに「extension=imagick.so」を追記しなさい、と指示されたので、そうしておく。

/usr/lib64/php/modules/配下に「imagick.so」というファイルが作成されたことを確認。

[root@nobuneko bin]# /etc/rc.d/init.d/httpd restart
