c++ - MinGw 4.7.0 不使用#include 编译代码

Question

MinGw 4.7.0 boost 1.47
代码:

#include <iostream>
#include <boost/thread.hpp>
int main(int argc, char *argv[])
{
std::cout<<"In main"<<std::endl;
}

编译器字符串:

g++.exe -Wall -fexceptions  -g    -IC:\soft\ides_comp\mingw\include\boost_1_47_0  -c      D:\work\cpp_cb\mt1\main.cpp -o obj\Debug\main.o

它无法编译，无论我尝试了何种编译器选项，我都会遇到同样的错误。

它可以是什么？谢谢

这已在以后的 boost 版本中得到修复。在这里检查:

https://svn.boost.org/trac/boost/ticket/6165

更新 boost/config/stdlib/libstdcpp3.hpp:

#if defined(_GLIBCXX_HAVE_GTHR_DEFAULT) \
    || defined(_GLIBCXX_HAS_GTHREADS) \
    || defined(_GLIBCXX__PTHREADS) \
    || defined(WIN32)

添加了 _GLIBCXX_HAS_GTHREADS 和/或 WIN32(从上面的链接，查看补丁)。

WIN32 似乎有点蛮力，但没有它就无法工作(至少对我来说不是。我使用的是较旧的 bo​​ost 版本 1.42)。
