cygwin上编译RPC框架thrift

cygwin的配置就不多说了，缺什么就通过安装器安装好了。

在thrift的官网下载 thrift-0.11.0源码，通过cmake编译，生成Makefile之后，make出现编译错误

/cygdrive/d/work/thrift-0.11./mybuild $ make

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

make: *** [Makefile:：all] 错误 

查看cmake生成Makefile的日志，在某个cmake文件里设置了-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.")

如下修改：

if (NOT DEFINED CMAKE_CXX_STANDARD)
  if (MSVC AND MSVC_VERSION LESS )
    # MSVC  and earlier don't support template aliases so you have to use C++98
    set(CMAKE_CXX_STANDARD )
    message(STATUS "Setting C++98 as the default language level (for an older MSVC compiler).")
  else()
    #set(CMAKE_CXX_STANDARD ) # C++
    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()

继续编译，随即遇到编译错误：

make: *** [Makefile:：all] 错误 

这里我就直接修改源代码了：

#define _GNU_SOURCE
#include <string.h>

将这两行放在thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp的其他include头文件的前面，不然 #define _GNU_SOURCE 会被编译器忽略

随即又遇到编译错误:

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

这里又是cygwin的库问题了，不支持PTHREAD_MUTEX_RECURSIVE_NP，改成 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

链接单元测试时又出现库不兼容的问题。。。

CMakeFiles/UnitTests.dir/concurrency/MutexTest.cpp.o:MutexTest.cpp:(.rdata$.refptr._ZN6apache6thrift11concurrency5Mutex20ADAPTIVE_INITIALIZEREPv[.refptr._ZN6apache6thrift11concurrency5Mutex20ADAPTIVE_INITIALIZEREPv]+0x0)：对‘apache::thrift::concurrency::Mutex::ADAPTIVE_INITIALIZER(void*)’未定义的引用
collect2: 错误：ld 返回

make[]: *** [CMakeFiles/Makefile2:：lib/cpp/test/CMakeFiles/UnitTests.dir/all] 错误
make: *** [Makefile:：all] 错误 

自适应锁在cygwin的最新版是没有的，就给它弄个默认的，该咋死咋死吧：

#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，完美编译成功！
