  在用cocos2d-x3.2 + protobuf編譯Android項(xiàng)目的時(shí)候,，protobuf出現(xiàn)了兩個問題：

 

1. 首先是config.h找不到,，查閱自后說是通過命令或工具生成的,，里面的內(nèi)容根據(jù)不同平臺是不一樣的（引用一些用到的庫,，例如hash_map,hash_set等,，和部分宏定義）,，那么就要在自己手動生成,，或者自己創(chuàng)建一個空的config，自己把一些引用到的庫加進(jìn)去,，為了能快速編譯通過,，我就自己創(chuàng)建了一個config.h，沒有引用任何庫,。

 

  1. #ifndef _LINUX_CONFIG_H
  2. #define _LINUX_CONFIG_H

  4. #endif

然后找不到config.h的問題解決了,。

 

2.  然后是error "No suitable threading library available."

定位到common.cc文件中

#ifdef _WIN32
#define WIN32_LEAN_AND_MEAN // We only need minimal includes
#include <windows.h>
#define snprintf _snprintf // see comment in strutil.cc
#elif defined(HAVE_PTHREAD)
#include <pthread.h>
#else
#error "No suitable threading library available."
#endif

發(fā)現(xiàn)是找不到HAVE_PTHREAD宏定義，導(dǎo)致沒有引用pthread庫,，直接用#include <pthread.h>替換#error "No suitable threading library available."這句代碼,，又會導(dǎo)致其他文件找不到；那么可能其它地方也引用了HAVE_PTHREAD宏,，那這個宏是protobuf庫根據(jù)不同平臺定義的呢,，還是該我們自己加呢，如果是自己加又應(yīng)該加在哪里呢,？

聯(lián)想到config文件找不到的問題,，猜到可能是config文件中缺少一些代碼，看來不能用空的config,，那么就直接在config.h中加上 #define HAVE_PTHREAD 即可,。

  1. #ifndef _LINUX_CONFIG_H
  2. #define _LINUX_CONFIG_H

  4. #define HAVE_PTHREAD

  6. #endif

 之后編譯通過。,。,。

 

如果是有完美強(qiáng)迫癥的、或者要求高效率（使用hash_map/unordered_map等）,，那么就在linux上用configure生成一個config.h吧,，下面附上一個完整生成的：

  1. /* config.h.  Generated from config.h.in by configure.  */
  2. /* config.h.in.  Generated from configure.ac by autoheader.  */

  4. /* the name of <hash_map> */
