使用thrift大量編譯警告消息方法

<a href="http://https//issues.apache.org/jira/browse/THRIFT-1824" target="_blank">https://issues.apache.org/jira/browse/THRIFT-1824</a>

背景：

當在使用thrift時，如果我們的代碼也采用automake方式編譯，這樣就存在config.h檔案沖突，原因是thrift的Thread.h檔案include它時，沒有目錄修飾。

config.h:

在成功編譯thrift後，會在它的thrift目錄下生成一個config.h檔案，這個檔案實際是由automake産生的，如下所示 ：

&gt; ls thrift

async        config.h   protocol  server                   TDispatchProcessor.h  TLogging.h    transport

concurrency  processor  qt        TApplicationException.h  Thrift.h              TProcessor.h  TReflectionLocal.h

concurrency/Thread.h：

在Thread.h頭檔案中會包含這個頭檔案，遺憾的是Thread.h是對外的公共檔案，也就是使用thrift會直接看到它，而config.h被include時，未加任何目錄修飾，這就是收到大量編譯警告的原因。

#ifdef HAVE_CONFIG_H

#include

#endif

ERROR MESSAGE:

隻需要将Thread.h中的#include 注釋掉，下面的大量編譯警告即可消息，而且thrift編譯也沒有問題。
