IANA time zone database. • This functionality requires several new types to be added to the library: • tzdb • tzdb_list • time_zone • zoned_time • time_zone_link • ambiguous_local_time • nonexistent_local_time for time zone data We had a few options... • Ship the entire IANA time zone database with the library The IANA time zone database is huge (1.25MB) – we would have some very unhappy customers if their for time zone data We had a few options... • Ship the entire IANA time zone database with the library The IANA time zone database is huge (1.25MB) – we would have some very unhappy customers if their

-C build • 以下命令和上一个等价，但更跨平台： • > cmake --build build • 执行生成的 a.out ： • > build/a.out 为什么需要库（ library ） • 有时候我们会有多个可执行文件，他们之间用到的某些功能是相同的，我们想把这些共用 的功能做成一个库，方便大家一起共享。 • 库中的函数可以被可执行文件调用，也可以被其他库文件调用。 可以生成可执行文件外，还可以通过 add_library 生成库 文件。 • add_library 的语法与 add_executable 大致相同，除了他需要指定是动态库还是静态库： • add_library(test STATIC source1.cpp source2.cpp) # 生成静态库 libtest.a • add_library(test SHARED source1
