继续安装php开发环境，
jpeg-6b make的时候错误：
./libtool –mode=compile gcc -O2 -I. -c ./jcapimin.c
make: ./libtool: Command not found
make: *** [jcapimin.lo] Error 127
看提示应该是没有安装libtool，由于才拿到手里的服务器，什么都没装，出现这个错误也正常。
解决办法：安装libtool
1 在上面的链接或者网上下载 libtool-2.2.6a.tar.gz，放到/usr/local/src/目录下，解压软件包到当前目录libtool-2.2.6下，并进入libtool-2.2.6目录，命令如下：
$ cd /usr/local/usr/ // 进入源码包所在目录
$ sudo tar zxvf libtool-2.2.6a.tar.gz // 解压缩
$ cd libtool-2.2.6 // 进入目录
2 使用“configure”命令检查并配置安装需要的系统环境，并生成安装配置文件，命令行如下：
$ ./configure
安装到默认路径就可以。
3 使用make命令编译源码文件并生成安装文件，命令如下：
$ sudo make // 编译
4 使用make install命令进行安装，命令如下：
$ sudo make install // 安装
5 复制libtool中的config.sub和config.guess文件至jpeg-6b根目录，命令如下：
$ cd /usr/local/src/jpeg-6b/
$ sudo cp /usr/local/share/libtool/config/config.sub .
$ sudo cp /usr/local/share/libtool/config/config.guess .
6 重新配置并编译、安装jpeg-6b，命令如下：
$ sudo ./configure \
> –prefix=/usr/local/jpeg6/ \ // 安装时将软件安装到/usr/local/jpeg6目录下
> –enable-shared \ // 建立共享库使用的GNU的libtool
> –enable-static // 建立静态库使用的GNU的libtool
$ sudo make // 编译
$ sudo make install // 安装
7 Done.

Continue to install the PHP environment.
An error occured when make jpeg-6b:
./libtool –mode=compile gcc -O2 -I. -c ./jcapimin.c
make: ./libtool: Command not found
make: *** [jcapimin.lo] Error 127
According the prompt, the libtool isn’t installed. It’s normal to have this error on a bare machine.
Solution: install libtool, of course!
1. Download the file libtool-2.2.6a.tar.gz on the above link or the official site, put it under /usr/local/src/, and extract it into libtool-2.2.6/ and then enter the current directory. The commands as follows:
$ cd /usr/local/usr/ // enter the directory where the source code is
$ sudo tar zxvf libtool-2.2.6a.tar.gz // extract the file
$ cd libtool-2.2.6 // enter the current directory
2. Check and configure the installation environment with “configure” command, which will generate installation configuration file. The command line as follows:
$ ./configure
we can just install it in the default path.
3. use the make command to compile the source file and generate the installation file:
$make // compile
4. use command make install to install:
$ make install // install
5. copy the config.sub and config.guess of libtool to jpeg-6b/, command as follows:
$ cd /usr/local/src/jpeg-6b/
$ sudo cp /usr/local/share/libtool/config/config.sub
$ sudo cp /usr/local/share/libtool/config/config.guess
6. reconfigure, compile and install jpeg-6b, commands as follows:
$ sudo ./configure \
> –prefix=/usr/local/jpeg6/ \ //install the software into /usr/local/jpeg6
> –enable-shared \ // GUN’s libtool will be used when creating shared lib
> –enable-static // GUN’s libtool will be used when creating static lib
$ sudo make // compile
$ sudo make install // install
7. Done
