I want to use boost to read a text file like this :
boost::iostreams::file_source file(filename.c_str());
But, when I want to get each single line with getline(), it doesn't compile
:
while (std::getline(file, line)) { ...} // COMPILATION ERROR
What's the equivalent in boost for std::getline() ?
You can use boost::iostreams::stream.

#include <boost/iostreams/device/file.hpp>
#include <boost/iostreams/stream.hpp>
#include <istream>

int main() {
    std::string filename("test");
    boost::iostreams::stream<boost::iostreams::file_source> 
file(filename.c_str());
    std::string line;
    while (std::getline(file, line)) { }
}
