php提示undefined function imagecreatefromstring

直接上代码

#如果报错libtool,先安装libtool
wget https://ftpmirror.gnu.org/libtool/libtool-2.4.6.tar.gz
tar -zxvf libtool-2.4.6.tar.gz
cd libtool-2.4.6
./configure
make && make install

#安装jpeg6b
#预新建需要的目录，源码安装不会自动生成下面的目录
mkdir /usr/local/jpeg6b/inculde
mkdir /usr/local/jpeg6b/man
mkdir /usr/local/jpeg6b/bin
mkdir /usr/local/jpeg6b/lib
mkdir /usr/local/jpeg6b/man/man1
wget http://www.ijg.org/files/jpegsrc.v6b.tar.gz

tar -zxvf jpegsrc.v6b.tar.gz
cd jpeg-6b/
cp /usr/share/libtool/config/config.sub ./
cp /usr/share/libtool/config/config.guess ./

#编辑安装
./configure --prefix=/usr/local/jpeg6b --enable-static --enable-shared
make && make install

#然后重新编译安装php,在configure后面新增，原来的编译脚本可以新建一个php文件用phpinfo()，查看之前的编译详情;
