i am using a class in the program which is defined like this
#include<iterator>
namespace utf8
{
template <typename octet_iterator>
class iterator : public std::iterator
<std::bidirectional_iterator_tag, uint32_t> {
octet_iterator it;
octet_iterator range_start;
octet_iterator range_end;
public:
iterator () {};
explicit iterator (const octet_iterator& octet_it,
const octet_iterator& range_start,
const octet_iterator& range_end) :
it(octet_it), range_start(range_start), range_end
(range_end)
{
if (it < range_start || it > range_end)
throw std::out_of_range("Invalid utf-8 iterator
position");
}
// the default "big three" are OK
octet_iterator base () const { return it; }
uint32_t operator * () const
{
octet_iterator temp = it;
return next(temp, range_end);
}
bool operator == (const iterator& rhs) const
{
if (range_start != rhs.range_start || range_end !=
rhs.range_end)
throw std::logic_error("Comparing utf-8 iterators
defined with different ranges");
return (it == rhs.it);
}
bool operator != (const iterator& rhs) const
{
return !(operator == (rhs));
}
iterator& operator ++ ()
{
next(it, range_end);
return *this;
}
iterator operator ++ (int)
{
iterator temp = *this;
next(it, range_end);
return temp;
}
iterator& operator -- ()
{
prior(it, range_start);
return *this;
}
iterator operator -- (int)
{
iterator temp = *this;
prior(it, range_start);
return temp;
}
}; // class iterator
};///namespace utf8
I am declaring an object of this class in the main program
utf8::iterator<char*> it(line.begin(), line.begin(), line.end());
the program compiles perfectly well on windows but is not compiling
on linux with the following problems.
utf8_ex.cpp:60: error: no matching function for call to
`utf8::iterator(__gnu_cxx::__normal_iterator<char*,
std::basic_string<char, std::char_t
raits<char>, std::allocator<char> > >,
__gnu_cxx::__normal_iterator<char*, std::
basic_string<char, std::char_traits<char>, std::allocator<char> > >,
__gnu_cxx::
__normal_iterator<char*, std::basic_string<char,
std::char_traits<char>, std::al
locator<char> > >)'
the namespace __gnu_cxx is defined in libstdc++ which i have
installed from this site.
http://www.pxh.de/fs/gsmlib/download/content.html (pl. look for
libstdc++ on this page)
pl. help.
