I am trying to compile against the boost::regex library, but as soon as I try and use the regex_search() function, it barfs:
$ g++ -Wall -L/cygdrive/c/Users/Adrian/Downloads/boost_1_53_0/stage/lib -std=c++0x exec.cpp -lboost_regex -o exec
exec.cpp: In function ‘int main(int, char**, char**)’:
exec.cpp:32:3: error: ‘regex_serach’ is not a member of ‘boost’
makefile:3: recipe for target `exec' failed
make: *** [exec] Error 1
Here is the some sample code that brings up this error:
#include <boost/regex.hpp>
int main(int argc, char* argv[], char* env[])
{
typedef boost::match_results<string::const_iterator> matches_t;
typedef matches_t::const_reference match_t;
boost::regex x("");
string str;
matches_t what;
boost::match_flag_type flags = boost::match_default;
boost::regex_serach(str.begin(), str.end(), what, x, flags);
return 0;
}
Line 32 is the line where regex_search is on. The g++ version is 4.5.3 under cygwin. Boost version is 1.53. If I comment out the regex_search line, it compiles fine. Ideas?
#include <boost/regex.hpp>
int main(int argc, char* argv[], char* env[])
{
typedef boost::match_results<std::string::const_iterator> matches_t;
typedef matches_t::const_reference match_t;
boost::regex x("");
const std::string str;
matches_t what;
boost::match_flag_type flags = boost::match_default;
regex_search(str.begin(), str.end(), what, x, flags);
return 0;
}
Three issues - string is in std namespace, requires to be called out accordingly. Second the regex_search template defines an iterator for a const string so declare it that way. Lastly regex_search is not part of boost namespace and there was a typo in the regex_seRAch. The above compiles and executes fine against boost 1.53.
