八、安装出现的问题及解决方法：
1) Configure: error: xml2-config not found. Please check your libxml2 installation.
#yum install libxml2 libxml2-devel (For RedHat & Fedora)

4) Configure: error: Please reinstall the libcurl distribution -
easy.h should be in <curl-dir>/include/curl/

10) Configure: error: Please reinstall the ncurses distribution
# yum install ncurses ncurses-devel
11) Checking for unixODBC support… configure: error: ODBC header file ‘/usr/include/sqlext.h’ not found!
# yum install unixODBC-devel
12) Configure: error: Cannot find pspell
# yum install pspell-devel
13) configure: error: mcrypt.h not found. Please reinstall libmcrypt.
# yum install libmcrypt libmcrypt-devel (For Redhat & Fedora)
# apt-get install libmcrypt-dev
14) Configure: error: snmp.h not found. Check your SNMP installation.
# yum install net-snmp net-snmp-devel
15)
/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [sapi/cgi/php-cgi] Error 1
# yum install libtool-ltdl.x86_64 libtool-ltdl-devel.x86_64
16）
为php编译xcache模块的时候，需要运行phpize
得到了一个错误
#/usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20041225
Zend Module Api No: 20060613
Zend Extension Api No: 220060519
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF
environment variable is set correctly and then rerun this script.
通过安装 autoconf 可以解决
CentOS下执行 yum install autoconf 即可
ubuntu下执行 apt-get install autoconf 即可
17）
# /usr/local/php/bin/phpize
Cannot find config.m4.
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module
修改方法：
[root@centos lnmp]# cd php-5.2.14ext/
[root@centos ext]# ./ext_skel --extname=my_module
Creating directory my_module
Creating basic files: config.m4 config.w32 .cvsignore my_module.c php_my_module.h CREDITS EXPERIMENTAL tests/001.phpt my_module.php [done].
To use your new extension, you will have to execute the following steps:
1. $ cd ..
2. $ vi ext/my_module/config.m4
3. $ ./buildconf
4. $ ./configure --[with|enable]-my_module
5. $ make
6. $ ./php -f ext/my_module/my_module.php
7. $ vi ext/my_module/my_module.c
8. $ make
Repeat steps 3-6 until you are satisfied with ext/my_module/config.m4 and
step 6 confirms that your module is compiled into PHP. Then, start writing
code and repeat the last two steps as often as necessary.
[root@centos ext]# cd my_module/
[root@centos my_module]# vim config.m4
根据你自己的选择将
dnl PHP_ARG_WITH(my_module, for my_module support,
dnl Make sure that the comment is aligned:
dnl [ --with-my_module Include my_module support])
修改成
PHP_ARG_WITH(my_module, for my_module support,
Make sure that the comment is aligned:
[ --with-my_module Include my_module support])
或者将
dnl PHP_ARG_ENABLE(my_module, whether to enable my_module support,
dnl Make sure that the comment is aligned:
dnl [ --enable-my_module Enable my_module support])
修改成
PHP_ARG_ENABLE(my_module, whether to enable my_module support,
Make sure that the comment is aligned:
[ --enable-my_module Enable my_module support])
[root@centos my_module]# vim my_module.c
将文件其中的下列代码进行修改
/* Every user visible function must have an entry in my_module_functions[].
*/
function_entry my_module_functions[] = {
PHP_FE(say_hello, NULL) /* ?添加着一行代码 */
PHP_FE(confirm_my_module_compiled, NULL) /* For testing, remove later. */
{NULL, NULL, NULL} /* Must be the last line in my_module_functions[] */
};
在文件的最后添加下列代码
PHP_FUNCTION(say_hello)
{
zend_printf("hello sdomain!");
}
再修改：php_sdomain.h
vi php_sdomain.h
在PHP_FUNCTION(confirm_my_module_compiled ); /* For testing, remove later. */ 这行的下面添加一行：
PHP_FUNCTION(say_hello); /* For testing, remove later. */
保存文件退出
然后我们就可以在这个目录下使用上面的命令了
/usr/local/php/bin/phpize
执行以后会看到下面的
[root@ns sdomain]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20020918
Zend Module Api No: 20020429
Zend Extension Api No: 20050606
[root@ns sdomain]#
然后执行./configure --with-php-config=/usr/local/php/bin/php-config
然后执行make
make install
然后他会把对应的so文件生成放到PHP安装目录下面的一个文件夹，并提示在在什么地方，然后再把里面的SO文件拷到你存放SO文件的地方
即你在php.ini里面的extension_dir所指定的位置
最后一步是你在php.ini文件中打开这个扩展
extension=sdomain.so
然后
重新起动apache
以上错误都是在整个编译安装遇到的问题，然后结合网上的资料，找到的解决方法，总结到这个地方，希望能帮到大家！
