最后的准备，编译 zendAPI

操作系统我们假定是类 unix 操作系统，采用非源码文件夹编译。

创建工作目录

cd ~/
mkdir workspace
cd workspace
mkdir build-zendapi

获取源码

您可以直接 clone 指定的分支，比如 master 分支。到目前为止 zendAPI 发布了一个版本 zapi-0.0.2-snapshot。

git clone https://github.com/qcoreteam/zendapi.git zendapidevel
git checkout master

默认参数编译

如果您的 PHP 安装在标准路径，可以用下面的命令进行编译

cd build-zendapi
cmake ../zendapidevel

如果您想安装到特定的路径，可以使用下面的命名进行编译

cd build-zendapi
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/zapi ../zendapidevel

如果您的 PHP 没有安装在标准路径，假定您安装在 /usr/local/php-7.1.5 目录下，那么您可以使用下面的命令进行编译

cd build-zendapi
cmake -DZAPI_OPT_PHP_ROOT_PATH=/usr/local/php-7.1.5 ../zendapidevel

如果您想给编译器指定额外的选项参数，比如您想用 c++14 标准进行编译，您可以使用下面的命令进行编译

cd build-zendapi
cmake -DCMAKE_CXX_FLAGS="-std=c++14" ../zendapidevel

如果您想使用特定版本的编译器进行编译，比如我自己，我自己编译了 clang 3.5， 按照路径为 /usr/local/llvm-3.5/bin/clang++，这个路径没有在 PATH 环境变量里面，那么我们可以使用下面的命令进行编译

cd build-zendapi
cmake -DCMAKE_C_COMPILER=/usr/local/llvm-3.5/bin/clang \
      -DCMAKE_CXX_COMPILER=/usr/local/llvm-3.5/bin/clang++ ../zendapidevel

现在我假定在我本机使用如下命令进行编译, PHP 安装在 /usr/local/php7/, 操作系统为 MacOS

cmake -DCMAKE_C_COMPILER=/usr/local/bin/gcc-6 \
      -DCMAKE_CXX_COMPILER=/usr/local/bin/g++-6 -DCMAKE_BUILD_TYPE=Debug ../zendapidevel

如果一切正常的话，您将看到如下的结果

如果有错误，您可以根据具体的错误信息进行排查，如果不能解决，您可以到我们的 segmentfault 技术圈进行交流讨论
如果没有错误输入一下命名进行编译, -j 指定编译进程数，根据 CPU 线程数定

make -j 8

如果整个编译过程没有错误的话，您将看到如下的输出，如果有错误，麻烦您通知我们

[100%] Linking CXX shared library ../lib/libzapi.dylib
[100%] Built target zapi

最后输入以下命令进行安装

make install

安装完成后您将看到如下输出
