無論是查書或google，他們都建議我如下撰寫讀檔程式碼：
bool CmdParser::openDofile(const string& dof)
{
ifstream _dofile(dof, ios::in);
...
然而，compile總是不能過。
cmdParser.cpp: In member function `bool CmdParser::openDofile(const
std::string&)':
cmdParser.cpp:36: error: no matching function for call to
`std::basic_ifstream<char, std::char_traits<char> >::basic_ifstream(const
std::basic_string<char, std::char_traits<char>, std::allocator<char> >&,
const std::_Ios_Openmode&)'
/usr/lib/gcc/i386-redhat-linux/3.4.4/../../../../include/c++/3.4.4/iosfwd:90:
note: candidates are: std::basic_ifstream<char, std::char_traits<char>
>::basic_ifstream(const std::basic_ifstream<char, std::char_traits<char> >&)
/usr/lib/gcc/i386-redhat-linux/3.4.4/../../../../include/c++/3.4.4/fstream:524:

_Traits>::basic_ifstream(const char*, std::_Ios_Openmode) [with _CharT =
char, _Traits = std::char_traits<char>]

note: std::basic_ifstream<_CharT, _Traits>::basic_ifstream()
[with _CharT = char, _Traits = std::char_traits<char>]
請問問題出在哪裡呢？謝謝
順便補充：
void
CmdParser::closeDofile()
{
_dofile.close();
請問為什麼沒辦法compile過呢？
查遍網路也得不到答案:(
謝謝
