Please run \texttt{make} in the gStore root directory to compile the gStore code, link the ANTLR lib, and build executable ``gbuild'', ``gquery'', ``gserver'', ``gclient'', ``gconsole''. What is more, the api of gStore is also built now.

gStore是一个绿色软件，你只需要用一个指令对它进行编译。请在gStore根目录下运行\texttt{make}来编译gStore代码，连接ANTLR 库，并生成可执行的``gbuild''、``gquery''、``gserver''、``gclient''、``gconsole''。 另外，gStore的api也在此时生成。
|
||||
|
||||
如果你想使用gStore的API样例，请运行\texttt{make\ APIexample}编译C++ API和Java API的样例代码。关于API的更多细节，请参阅\hyperref[chapter05]{【API】}一章。
