libuuid是一個開源的用於生成UUID(Universally Unique Identifier，通用唯一標識符)的庫。
可從https://sourceforge.net/projects/libuuid/ 下載，最新版本為1.0.3，更新於2013年4月27日，此庫僅支持在類Linux下編譯使用。
之前在Windows上，我們產生guid（uuid在Windows上的叫法，是一個東西）可以使用API函數CoCreateGuid。
CrossGuid是一個最小的跨平台C ++ GUID庫。它在給定平台上使用最好的本機GUID / UUID生成器，並具有用於解析，字符串化和比較ID的通用類。
可從https://github.com/graeme-hill/crossguid下載使用
接下來，我們在linux ubuntu上編譯學習以下這兩個庫：
- libuuid
libuuid已經為我們提供了configure，直接./configure & make & make install三部曲即可，最終編譯生成libuuid.a供程序鏈接使用，自帶的一個C測試例子test_uuid.c，全部的終端執行如下：

- crossguid
crossguid則為我們提供了CMakeLists.txt，方便我們使用cmake的方式來構建，構建成功后會生成一個libcrossguid.a 靜態庫和測試程序 crossguid-test ，全部的終端執行如下：
