[英]Where are PHP extensions when installing from source?
When I try to run a PHP scripts I get the following errors: 当我尝试运行PHP脚本时,出现以下错误:
Warning: PHP Startup: Unable to load dynamic library '/home/user/php-5.4.28/installdir/include/php/ext/php_bz2.so' - /home/user/php-5.4.28/installdir/include/php/ext/php_bz2.so: cannot open shared object file: No such file or directory in Unknown on line 0
php.ini: php.ini:
extension_dir = "/home/user/php-5.4.28/installdir/include/php/ext"
Content at extension_dir path: extension_dir路径中的内容:
~/php-5.4.28/installdir/include/php/ext$ ls
date ereg gd iconv libxml mysqli pcre session sqlite3 xml
dom filter hash json mbstring mysqlnd pdo spl standard
Where do I locate the extension? 我在哪里找到扩展名? I have installed PHP from source.
我已经从源代码安装了PHP。 All the errors and phpinfo() can be seen here on JSBin
所有错误和phpinfo()都可以在JSBin上看到
You don't have to locate the extension. 您不必找到扩展名。 You have to recompile PHP passing the option
--with-bz2
to the ./configure
script. 您必须重新编译PHP,将选项
--with-bz2
传递给./configure
脚本。 Bzip2 support is not enabled by default as official documentation says. 如官方文档所述 ,默认情况下未启用Bzip2支持。
./configure --with-bz2
Keep in mind that in order to compile PHP with this extension you need development headers and/or libraries. 请记住,为了使用此扩展编译PHP,您需要开发标头和/或库。 If they are missing
./configure
will fail saying what's missing. 如果缺少它们,。
./configure
将无法说出丢失的内容。 If this will happen simply use your package manager (apt, yum or zypper - distro dependent) to install required packages and retry. 如果发生这种情况,只需使用您的软件包管理器(apt,yum或zypper-依赖于发行版)安装所需的软件包并重试。
It's also likely that your PHP apps are using other extensions. 您的PHP应用程序也可能正在使用其他扩展。 The procedure is exactly the same.
步骤完全相同。 You just add more options.
您只需添加更多选项。 Let's say that curl is also needed, then:
假设还需要卷曲,那么:
./configure --with-bz2 --with-curl
will work - again more headers and packages needed. 将工作-再次需要更多的标题和包。
Remember to always use all the options you need as the results of former compilations are overwritten. 切记始终使用所需的所有选项,因为以前的编译结果会被覆盖。
