cygwin上編譯RPC框架thrift

cygwin的配置就很少說了，缺什麼就經過安裝器安裝好了。

在thrift的官網下載 thrift-0.11.0源碼，經過cmake編譯，生成Makefile以後，make出現編譯錯誤

/cygdrive/d/work/thrift-0.11.0/mybuild $ make

[ 1%] Building CXX object compiler/cpp/CMakeFiles/parse.dir/thrift/thrifty.cc.o

make: *** [Makefile:161：all] 錯誤 2

查看cmake生成Makefile的日誌，在某個cmake文件裏設置了-std=c++11，找到：

D:\work\thrift-0.11.0\build\cmake\DefineCMakeDefaults.cmake (2 hits)
Line 79: message(STATUS "Setting C++98 as the default language level (for an older MSVC compiler).")
Line 82: message(STATUS "Setting C++11 as the default language level.")

以下修改：

if (NOT DEFINED CMAKE_CXX_STANDARD)
  if (MSVC AND MSVC_VERSION LESS 1800)
    # MSVC 2012 and earlier don't support template aliases so you have to use C++98
    set(CMAKE_CXX_STANDARD 98) 
    message(STATUS "Setting C++98 as the default language level (for an older MSVC compiler).")
  else()
    #set(CMAKE_CXX_STANDARD 11) # C++11
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")
    message(STATUS "Setting C++11 as the default language level.")
  endif()
  message(STATUS "To specify a different C++ language level, set CMAKE_CXX_STANDARD")
endif()

 繼續編譯，隨即遇到編譯錯誤：

[ 11%] Building CXX object lib/cpp/CMakeFiles/thrift_static.dir/src/thrift/transport/THttpServer.cpp.o
/cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp: 在成員函數‘virtual void apache::thrift::transport::THttpServer::parseHeader(char*)’中:

make: *** [Makefile:161：all] 錯誤 2

這裏我就直接修改源代碼了：

#define _GNU_SOURCE
#include <string.h>

將這兩行放在thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp的其餘include頭文件的前面，否則 #define _GNU_SOURCE 會被編譯器忽略

 隨即又遇到編譯錯誤:

/cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/concurrency/Mutex.cpp: 在靜態成員函數‘static void apache::thrift::concurrency::Mutex::RECURSIVE_INITIALIZER(void*)’中:

make[1]: *** [CMakeFiles/Makefile2:11

這裏又是cygwin的庫問題了，不支持PTHREAD_MUTEX_RECURSIVE_NP，改爲 PTHREAD_MUTEX_RECURSIVE

#ifdef PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP
void Mutex::RECURSIVE_INITIALIZER(void* arg) {
  //init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_RECURSIVE_NP);
  init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_RECURSIVE);
}
#endif

 連接單元測試時又出現庫不兼容的問題。。。

CMakeFiles/UnitTests.dir/concurrency/MutexTest.cpp.o:MutexTest.cpp:(.rdata$.refptr._ZN6apache6thrift11concurrency5Mutex20ADAPTIVE_INITIALIZEREPv[.refptr._ZN6apache6thrift11concurrency5Mutex20ADAPTIVE_INITIALIZEREPv]+0x0)：對‘apache::thrift::concurrency::Mutex::ADAPTIVE_INITIALIZER(void*)’未定義的引用

make: *** [Makefile:161：all] 錯誤 2

自適應鎖在cygwin的最新版是沒有的，就給它弄個默認的，該咋死咋死吧：

#ifdef PTHREAD_ADAPTIVE_MUTEX_INITIALIZER_NP
void Mutex::ADAPTIVE_INITIALIZER(void* arg) {
  // From mysql source: mysys/my_thr_init.c
  // Set mutex type to "fast" a.k.a "adaptive"
  //
  // In this case the thread may steal the mutex from some other thread
  // that is waiting for the same mutex. This will save us some
  // context switches but may cause a thread to 'starve forever' while
  // waiting for the mutex (not likely if the code within the mutex is
  // short).
  init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_ADAPTIVE_NP);
}
#else
void Mutex::ADAPTIVE_INITIALIZER(void* arg) {
  // From mysql source: mysys/my_thr_init.c
  // Set mutex type to "fast" a.k.a "adaptive"
  //
  // In this case the thread may steal the mutex from some other thread
  // that is waiting for the same mutex. This will save us some
  // context switches but may cause a thread to 'starve forever' while
  // waiting for the mutex (not likely if the code within the mutex is
  // short).
  init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_NORMAL);
}    
#endif

 OK，至此，完美編譯成功！
