在ubuntu上成功安裝了zlib-1.2.7，libpng-1.5.9，freetype-2.6.4，jpeg-9和libgd-2.1.0。安裝GD模塊for php7，配置php時出錯
但是當我配置PHP7：
./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：配置：錯誤：問題的libpng（A |左右）或libz進行（A |左右）。
中的config.log：
