Hello,
for some time now I've been trying to split a given string at whitespaces:
"A B C" -> "A", "B", "C". I want to use boost/algorithm/string
#include "boost/algorithm/string/split.hpp"
#include "boost/algorithm/string/compare.hpp"
std::vectorstd::string tokenize(const std::string& text )
{
std::vectorstd::string tokens;
boost::algorithm::split(tokens, text, boost::algorithm::is_equal(" "));
return tokens;
}
but compilation on gcc 4.9.0 / boost 1.55.0 just gives:
test.cpp: In function 'std::vector tokenize(const
string&)':
test.cpp:40:71: error: no matching function for call to
'boost::algorithm::is_equal::is_equal(const char [2])'
boost::algorithm::split(tokens, text, boost::algorithm::is_equal(" "));
^
test.cpp:40:71: note: candidates are:
In file included from /usr/include/boost/algorithm/string/finder.hpp:24:0,

/usr/include/boost/algorithm/string/compare.hpp:34:16: note: no known
conversion for argument 1 from 'const char [2]' to 'const
boost::algorithm::is_equal&'
What is wrong there?
Thanks,
Florian
