雖然我多次編譯php 5.5.10，但仍然無法獲得webp支持啓用，這是由「http://cn2.php.net/manual/zh/function.imagewebp.php」描述的。 這裏是我的編譯設置：如何編譯php以啓用webp支持？
CentOS release 5.8 (Final) x86_64
freetype-2.4.6
jpeg-8c
libpng-1.2.35
gd-2.1.0
PHP編譯命令
./configure --prefix=/apps/lib/php-5.5.10 --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-mysqlnd --enable-fpm --enable-mbstring --enable-mbregex --with-zlib-dir=/apps/lib/zlib --enable-pcntl --enable-sockets --enable-ftp --enable-soap --enable-bcmath --disable-debug --enable-sockets --enable-inline-optimization --disable-rpath --with-mysql=/apps/svr/mysql5 --with-libxml-dir=/apps/lib/libxml --with-jpeg-dir=/apps/lib/jpeg --with-iconv-dir=/apps/lib/libiconv --with-mcrypt=/apps/lib/libmcrypt --with-freetype-dir=/apps/lib/freetype --with-gd=/apps/lib/gd-2.1.0 --with-openssl-dir=/apps/lib/openssl --with-openssl=/apps/lib/openssl --with-curl=/apps/lib/curl --with-png-dir=/apps/lib/libpng --enable-opcache=no
，雖然我按照步驟通過 'http://techglimpse.com/install-upgrade-php55-yum/' 安裝PHP終於得到這個輸出GD

對於系統管理員的關注，我需要部署php的編譯版本。 編譯php或lib gd時我錯過了什麼重要的東西嗎？
我認爲這應該以超級用戶的身份提出。 – enapupe
嗨@enapupe，你會更具體嗎？ 「被超級用戶問」我不明白。 – criver
