Question

最简单的例子：

#include <boost/iostreams/filtering_stream.hpp>
#include <boost/iostreams/filter/bzip2.hpp>  
int main() {
  boost::iostreams::filtering_istream in;
  in.push(boost::iostreams::bzip2_compressor());
  return 0;
}

使用以下命令在我的机器上编译正常：

g++ -lboost_iostreams  simple.cpp

但是当c ++ 0x包含在以下任一实例中时失败：

g++ -lboost_iostreams  simple.cpp -std=c++0x
g++ -lboost_iostreams  simple.cpp -std=gnu++0x

下面是一个疯狂的长错误信息。代码中的内容导致c++0x失败？怎么解决这个问题？我运行了这三台机器，每台机器都有不同的配置 - 它在两台机器上运行失败，但在Ubuntu机器上安装时运行正常。

Answer 1

使用-std=c++0x编译的代码不会与没有-std=c++0x编译的代码ABI兼容。您需要在启用-std=c++0x的情况下自行构建Boost;这可以通过将cxxflags参数传递给bjam / b2来完成。

boost :: iostreams :: bzip2_compressor仅在c ++ 0x时失败
