boost :: iostream :: filtering_streambuf的编译错误 [英] compile error for boost::iostream::filtering_streambuf

问题描述

下面的代码可以得到下面的编译错误。

p>

in.push（uncompressed_string）;

错误6错误C2027：使用未定义类型'boost :: STATIC_ASSERTION_FAILURE' c：\program files（x86）\boost\boost_1_47\boost\iostreams\chain.hpp 488 1代理

  boost :: iostreams :: filtering_streambuf& boost :: iostreams :: input>在; 
 ostringstream uncompressed_string; 
 ostringstream compressed_string; 
 
 
 uncompressed_string<< f 
 
 in.push（boost :: iostreams :: bzip2_compressor（））; 
 in.push（uncompressed_string）; 
 
 boost :: iostreams :: copy（uncompressed_string，compressed_string）; 
  

解决方案

错误是由于推送一个 过滤流作为其设备。

  #include< sstream> ; 
 #include< string> 
 //＃include< boost / iostreams / filtering_stream.hpp> 
 #include< boost / iostreams / filtering_streambuf.hpp> 
 #include< boost / iostreams / filter / bzip2.hpp> 
 #include< boost / iostreams / copy.hpp> 
 int main（）
 {
 std :: string buf =this is a test\\\
; 
 
 // boost :: iostreams :: filtering_istream in; //我认为这更简单
 boost :: iostreams :: filtering_streambuf& boost :: iostreams :: input>在; 
 in.push（boost :: iostreams :: bzip2_compressor（））; 
 std :: istringstream uncompressed_string（buf）; 
 // in.push（boost :: make_iterator_range（buf））; //另一个选项
 in.push（uncompressed_string）; 
 std :: ostringstream compressed_string; 
 boost :: iostreams :: copy（in，compressed_string）; 
 
 std :: cout<< compressed_string.str（）; 
} 
  

使用gcc 4.6.1和boost 1.46测试

 〜$ ./test | bzcat 
这是一个测试
  

Just trying to compress a string with bzip2 so that I can send it over a pipe with ReadFile.

The following line earns me the following compile error.

in.push(uncompressed_string);

Error 6 error C2027: use of undefined type 'boost::STATIC_ASSERTION_FAILURE' c:\program files (x86)\boost\boost_1_47\boost\iostreams\chain.hpp 488 1 Agent

boost::iostreams::filtering_streambuf<boost::iostreams::input> in;
ostringstream uncompressed_string;
ostringstream compressed_string;


uncompressed_string << buf;

in.push(boost::iostreams::bzip2_compressor());
in.push(uncompressed_string);

boost::iostreams::copy(uncompressed_string, compressed_string);

解决方案

The error was due to pushing an output stream into an input filtering stream as its Device.

#include <sstream>
#include <string>
//#include <boost/iostreams/filtering_stream.hpp>
#include <boost/iostreams/filtering_streambuf.hpp>
#include <boost/iostreams/filter/bzip2.hpp>
#include <boost/iostreams/copy.hpp>
int main()
{
    std::string buf =  "this is a test\n";

    //boost::iostreams::filtering_istream in; // I think this is simpler
    boost::iostreams::filtering_streambuf<boost::iostreams::input> in;
    in.push(boost::iostreams::bzip2_compressor());
    std::istringstream uncompressed_string(buf);
    // in.push(boost::make_iterator_range(buf)); // another option
    in.push(uncompressed_string);
    std::ostringstream compressed_string;
    boost::iostreams::copy(in, compressed_string);

    std::cout << compressed_string.str();
}

tested with gcc 4.6.1 and boost 1.46

~ $ ./test | bzcat
this is a test
