希望能够打通论坛和移动App的数据



  • 今天又花了时间研究一下如何打通论坛和移动App的数据,现在稍微能够做到的是注册用户了,用户需要像论坛中的那样,提供用户名、密码以及电子邮箱,即可顺利地注册了。

  • 首先我看到的就是option选项。这个选项在cmake中的文档是这样的:

    Now let us consider making the MathFunctions library optional. In this tutorial there really isn’t any reason to do so, but with larger libraries or libraries that rely on third party code you might want to. The first step is to add an option to the top level CMakeLists file.

    # should we use our own math functions? option (USE_MYMATH "Use tutorial provided math implementation" ON)

    This will show up in the CMake GUI with a default value of ON that the user can change as desired. This setting will be stored in the cache so that the user does not need to keep setting it each time they run CMake on this project. The next change is to make the build and linking of the MathFunctions library conditional. To do this we change the end of the top level CMakeLists file to look like the following:

    # add the MathFunctions library? # if (USE_MYMATH) include_directories ("${PROJECT_SOURCE_DIR}/MathFunctions") add_subdirectory (MathFunctions) set (EXTRA_LIBS ${EXTRA_LIBS} MathFunctions) endif (USE_MYMATH) # add the executable add_executable (Tutorial tutorial.cxx) target_link_libraries (Tutorial ${EXTRA_LIBS}) 参考来源:这里

    在我看来,cmake中的option命令更像是一个宏,规定了是否定义这个宏以及这个宏所带来的连锁反应。option规定的这个宏,通过ON的设定来表示是否定义。
