php jpeg 6b 编译安装,Ubuntu搭建LAMP环境（jpeg-6b 安装错误 ，找不到libtool命令）

继续安装php开发环境，

jpeg-6bmake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.

English Version:

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
