c++ - .cpp 错误 : no match for 'operator<' in 'std::cerr < "Converting file \""'

Question

我正在尝试执行此代码 nmea2kml.cpp

但我不断收到以下错误。该程序还具有命令行参数 -f path Read file at given path (e.g./some/where/nmea.txt) 我应该更改什么才能运行该程序？由于编译器问题，我收到错误了吗？因为我把 cygwin、MinGW 编译器添加到 eclipse 中搞砸了!!我知道程序是正确的。别人已经用过了，得到了结果。(http://julien.cayzac.name/code/gps/)

看起来你写了std::cerr < "..." (< 运算符)你打算写 std::cerr << "..." 的地方(<< 运算符)。
