为php7安装GD模块，配置php时出错

Question

在ubuntu中成功安装zlib-1.2.7、libpng-1.5.9、freetype-2.6.4、jpeg-9和libgd-2.1.0。

但是当我为php7配置时：

./configure --prefix=/alidata/server/php7 --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mbstring --enable-pdo --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd  --with-openssl=/alidata/ssl --with-curl --with-zlib --with-zlib-dir=/usr/local --with-webp-dir --with-png-dir=/usr/local/lib --with-jpeg-dir=/usr/local/jpeg9 --with-freetype-dir=/usr/local/freetype --with-gd --enable-gd-native-ttf

我得到：配置：错误：libpng.(a|so) 或 libz.(a|so) 有问题。

在 config.log 中：

configure:33286: checking for png_write_image in -lpng

谁能帮帮我，谢谢！！！

这个选项可以帮助我处理 GD：

--with-gd=/usr/ --with-xpm-dir=/usr/ '--with-libdir=lib/x86_64-linux-gnu'
