face_detect 0.0.1をインストールする

０．改訂履歴

2007.10.23　新規作成

１．はじめに

　このドキュメントでは，OpenCV1.0.0で提供される顔認識用の関数？のface_detectを，PHPから呼び出す事ができる様にするPHP拡張機能のface_detect 0.0.1をインストールする手順を説明する．

　なお，使用しているOSは，RedHat Linux ES上で稼働している．

２．モジュールの入手

モジュールを入手する．

[root@uranos open]# curl -O http://www.netflowers.co.jp/face_detect/face_detect-0.0.1.tar.gz

----------------------------------------------------------------------
Libraries have been installed in:
   /www/system/InstallBin/open/face_detect-0.0.1/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.
----------------------------------------------------------------------

Build complete.
(It is safe to ignore warnings about tempnam and tmpnam).

次は，PHP.INIに以下の項目を追加する．

/usr/local/lib/php.ini
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613/" extension=face_detect.so

Apacheを利用している場合は，Apacheを再起動する．
