【PHP】libphpcpp.so编译

在本地增加了一个新的php扩展后，遇到依赖的libphpcpp.so没有装上，于是自己来编译安装

$ php -v

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/Cellar/php70/7.0.20_12/lib/php/extensions/no-debug-non-zts-20151012/thriftphp.so' - dlopen(/usr/local/Cellar/php70/7.0.20_12/lib/php/extensions/no-debug-non-zts-20151012/thriftphp.so, 9): Library not loaded: libphpcpp.so.2.0

安装步骤：

1、Clone代码库

git clone https://github.com/CopernicaMarketingSoftware/PHP-CPP.git

2、Mac下需要安装XCode，并运行安装组件

3、Mac下修改编译，修改Makefile 119行

LINKER_FLAGS            =   -shared

修改为

LINKER_FLAGS            =   -shared -undefined dynamic_lookup

如不修改就进行编译会遇到以下错误

Undefined symbols for architecture x86_64:
  "_OnUpdateString", referenced from:
      Php::Ini::fill(_zend_ini_entry_def*, int) in ini.o
…
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libphpcpp.so.2.0.0] Error 1

4、修改Makefile 179行

 ${LINKER} ${PHP_LINKER_FLAGS} -Wl,-soname,libphpcpp.so.$(SONAME) -o $@ ${COMMON_SHARED_OBJECTS} ${PHP_SHARED_OBJECTS}

修改为

 ${LINKER} ${PHP_LINKER_FLAGS} -Wl,-install_name,libphpcpp.so.$(SONAME) -o $@ ${COMMON_SHARED_OBJECTS} ${PHP_SHARED_OBJECTS}

5、make & make install

等运行成功，再来运行看看php -v，不报错了，搞定。
