PHP-X 测试提示libphpx.so: cannot open shared object

先总结下
编译都成功了，扩展cpp_ext.so也加到php.ini中了就是不能正常运行，
提示：'/usr/local/software/php/v71/lib/php/extensions/no-debug-non-zts-20160303/cpp_ext.so' - libphpx.so: cannot open shared object file: No such file or directory in Unknown on line 0
当添加了libphpx.so到php.ini再运行提示：
PHP Warning:  PHP Startup: Invalid library (maybe not a PHP library) 'libphpx.so' in Unknown on line 0

现在不理解libphpx.so的具体作用，github、wik.swoole.com上也没有明确如何使用这个，只是提到了添加编译后的扩展到php.ini中，帮忙解决下，多谢了！环境Ubtuntu16.04 php7以下是安装步骤。

1.Build libphpx.so
root@caojiabin:/home/PHP-X# cmake . -DPHP_CONFIG_DIR=/usr/local/software/php/v71/bin
PHP_INCLUDE_DIR: /usr/local/software/php/v71/include/php
-- Configuring done
-- Generating done
-- Build files have been written to: /home/PHP-X

root@caojiabin:/home/PHP-X# make -j 4
[100%] Built target phpx
root@caojiabin:/home/PHP-X# sudo make install
[100%] Built target phpx
Install the project...
-- Install configuration: "Debug"
Are you run command using root user?
-- Up-to-date: /usr/local/lib/libphpx.so
-- Up-to-date: /usr/local/include/phpx.h
-- Up-to-date: /usr/local/include/phpx_embed.h
root@caojiabin:/home/PHP-X#

2.编译cpp_ext
先修改Makefile指定php7
root@caojiabin:/home/PHP-X/examples/cpp_ext# cat Makefile
PHP_INCLUDE = `/usr/local/software/php/v71/bin/php-config --includes`
PHP_LIBS = `/usr/local/software/php/v71/bin/php-config --libs`
PHP_LDFLAGS = `/usr/local/software/php/v71/bin/php-config --ldflags`
PHP_INCLUDE_DIR = `/usr/local/software/php/v71/bin/php-config --include-dir`
PHP_EXTENSION_DIR = `/usr/local/software/php/v71/bin/php-config --extension-dir`

cpp_ext.so: extension.cpp
	c   -DHAVE_CONFIG_H -g -o cpp_ext.so -O0 -fPIC -shared extension.cpp -std=c  11 -lphpx ${PHP_INCLUDE} -I${PHP_INCLUDE_DIR}
test.so: test.cpp
	c   -DHAVE_CONFIG_H -g -o test.so -O0 -fPIC -shared test.cpp -std=c  11  -lphpx ${PHP_INCLUDE} -I${PHP_INCLUDE_DIR}\
	 -I${PHP_INCLUDE_DIR}/ext/swoole/include -I${PHP_INCLUDE_DIR}/ext/swoole
install: cpp_ext.so
	cp cpp_ext.so ${PHP_EXTENSION_DIR}/
clean:
	rm *.so

安装
root@caojiabin:/home/PHP-X/examples/cpp_ext# make install
cp cpp_ext.so `/usr/local/software/php/v71/bin/php-config --extension-dir`/
root@caojiabin:/home/PHP-X/examples/cpp_ext#

3.在php.ini中增加
extension = cpp_ext.so

4.运行测试例子
root@caojiabin:/home/PHP-X/examples/cpp_ext# /usr/local/software/php/v71/bin/php dump.php
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/software/php/v71/lib/php/extensions/no-debug-non-zts-20160303/cpp_ext.so' - libphpx.so: cannot open shared object file: No such file or directory in Unknown on line 0

5.当我试着添加libphpx.so到php.ini中再次运行提示如下
root@caojiabin:/home/PHP-X/examples/cpp_ext# /usr/local/software/php/v71/bin/php dump.php
PHP Warning:  PHP Startup: Invalid library (maybe not a PHP library) 'libphpx.so' in Unknown on line 0

安装
root@caojiabin:/home/PHP-X/examples/cpp_ext# make install
cp cpp_ext.so `/usr/local/software/php/v71/bin/php-config --extension-dir`/
root@caojiabin:/home/PHP-X/examples/cpp_ext#

3.在php.ini中增加
extension = cpp_ext.so
