继续在ubuntu下配置PHP开发环境，做到安装Apache服务器了，执行configure的时候，报错，具体如下

configure: error: Bundled APR requested but not found at ./srclib/. Download and unpack the corresponding apr and apr-util packages to ./srclib/.

google以后，发现这是需要下载apr和apr-utils 并解压到./srclib/, 再进行编译。

解决办法：

1.1 在上面的链接或者网上下载 apr-1.4.6.tar.gz和apr-util-1.4.1.tar.gz，放到/usr/local/src/目录下，解压软件包到当前目录的apr-1.4.6/和apr-util-1.4.1/下，命令如下：
$ cd /usr/local/usr/                                      // 进入源码包所在目录
$ sudo tar zxvf apr-1.4.6.tar.gz                  // 解压缩
$ sudo tar zxvf apr-util-1.4.1.tar.gz           // 解压缩

1.2 （现在我们依然在/usr/local/src/目录下）拷贝解压缩后的目录到httpd-2.4.4/srclib/apr和httpd-2.4.4/srclib/apr-util中，命令如下：
$ sudo cp -rf apr-1.4.6 httpd-2.4.4/srclib/apr
$ sudo cp -rf apr-util-1.4.1 httpd-2.4.4/srclib/apr-util

然后重新进入httpd目录，进行配置。

结果出现新的问题，如下：
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

又是一个依赖关系，，，，晕死算了。没办法，继续下吧。去http://pcre.org/下载

2.1 在上面的链接或者网上下载 pcre-8.32.tar.gz，放到/usr/local/src/目录下，解压软件包到当前目录的pcre-8.32下，并进入pcre-8.32目录，命令如下：
$ cd /usr/local/usr/                                      // 进入源码包所在目录
$ sudo tar zxvf pcre-8.32.tar.gz                  // 解压缩
$ cd pcre-8.32                                               // 进入目录

2.2 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 –prefix=/usr/local/pcre
选项–prefix=/usr/local/pcre作用，是在安装时将软件安装到/usr/local/pcre目录下

2.3 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

2.4 使用make install命令进行安装，命令如下：
$ sudo make install                                         // 安装
如果安装成功就会在/usr/local/pcre目录下生成bin、include、lib和share四个目录。如下图

安装完pcre以后，回到httpd目录下,

在./configure的时候加上–with-pcre=/usr/local/pcre即可。

这次终于成功configure了，然后make && make install。

大功告成！

English Version:

Continue to install the PHP environment.
An error occured when performing configure command during installing Apache server:

configure: error: Bundled APR requested but not found at ./srclib/. Download and unpack the corresponding apr and apr-util packages to ./srclib/.

Google it, I found that we need to download the apr and apr-utils , extract them to ./srclib/ and then compile.

Solution:

1.1 Download the file apr-1.4.6.tar.gz and apr-util-1.4.1.tar.gz on the above link or the official site, put them under /usr/local/src/, and extract them separately to apr-1.4.6/ and apr-util-1.4.1/. The commands as follows:

$ cd /usr/local/usr/            // enter the directory where the source code is
$ sudo tar zxvf apr-1.4.6.tar.gz           // extract the file
$ sudo tar zxvf apr-util-1.4.1.tar.gz      // extract the file

1.2 (remain under the /usr/local/src/)copy the extracted files above separately to directory httpd-2.4.4/srclib/apr/ and httpd-2.4.4/srclib/apr-util/, commands as follows:
$ sudo cp -rf apr-1.4.6 httpd-2.4.4/srclib/apr
$ sudo cp -rf apr-util-1.4.1 httpd-2.4.4/srclib/apr-util

enter the httpd directory to configure.

Another new problem arised:
configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

Another dependency?? oops… continue to download~~ go to the website http://pcre.org/.

2.1 Download the file pcre-8.32.tar.gz on the above link or the official site, put it under /usr/local/src/, and extract it to pcre-8.32/, and enter the current directory. The commands as follows:
$ cd /usr/local/usr/            // enter the directory where the source code is
$ sudo tar zxvf  pcre-8.32.tar.gz          // extract the file
$ cd pcre-8.32/                              // enter the current directory

2.2 Check and configure the installation environment with “configure” command, which will generate installation configuration file.  The command line as follows:
$ ./configure –prefix=/usr/local/pcre
“–prefix=/usr/local/pcre” means that the installing software will be installed under /usr/local/pcre.

2.3 use the make command to compile the source file and generate the installation file:
$sudo make                                                      // compile

2.4 use command make install to install:
$ sudi make install                                              // install
If the installation succeeded, there would be four directories(bin/, include/, lib/, share/)generated under /usr/local/pcre, as following picture:

after installing the pcre, return to the httpd directory, and add the option –with-pcre=/usr/local/pcre behind ./configure.

It succeeded~~, and then perform make and make install.
Done!

继续安装php开发环境，当安装最新的GD库文件，执行make命令的时候，出现了没有头文件的问题。错误代码如下：

error: png.h: No such file or directory

其实就是头文件的路径不对。

解决办法：

vim gd_png.c
将
#include “png.h”             
替换成：
#include “/usr/local/libpng/include/png.h”  
           
然后再make就可以了

注：include“”双引号里包含的是libpng安装的路径里的include文件夹

继续安装php开发环境，当安装到libpng的时候，输入make命令，确发现提示错误，没有找到makefile。

我还纳闷儿了，明明有makefile.am 和 makefile.in啊，configure以后不就生成makefile了嘛，于是又执行了一遍configure，结果在最后一行发现错误，如下。

configure: error: zlib not installed

google以后，发现大家都是用的这个方法解决：

Continue to install the PHP environment.
When install the libpng package after entering the make command, the error “cannot find the makefile” might occur.
I’m so confused~~,  the makefile.am and makefile.in obviously exsit in the directory. The makefile should be generated after configuring.
So I perform the configure command again, and then find this error:

configure: error: zlib not installed

Google it, find following solution that many people are using:
1. Enter the directory where the zlib source file is, and perform the make clean command to clean up zlib.
2. Reconfigure using  ./configure without  –prefix parameter.
3. Perform make and make isntall
4. Enter the libpng directory, execute the command ./configure –prefix=/usr/local/libpng.
5. Perform command make and make install.
