boost::regx error 请大虾们赐教

[littleeagle007]

使用boost库： boost_1_41_0

编译环境WIN32 VS2005


出错：

runtime error： boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::regex_error> >

搞了好久没有好办法搞的定，请各位大虾赐教一二，拜谢先。

代码
#include <boost/regex.hpp>
#include <iostream>
boost::regex e("(\\d{3, 4})[- ]?(\\d{4)})[- ]?(\\d{4})[- ]?(\\d{4})");
void print_captures(const std::string& regx, const std::string& text)
{
boost::regex e(regx);
boost::smatch what;
std::cout << "Expression: \"" << regx << "\"\n";
std::cout << "Text: \"" << text << "\"\n";
if (boost::regex_match(text, what, e, boost::match_extra))
{
unsigned i, j;
std::cout << "** Match found **\n Sub-Expressions: \n";
for (i = 0; i < what.size(); ++i)
std::cout << " $" << i << " = \"" << what[i] << "\"\n";
std::cout << " Captures:\n";
for (i = 0; i < what.size(); ++i)
{
std::cout << " $" << i << " = {";
for (j = 0; j < what.captures(i).size(); ++j)
{
if (j)
std::cout << ", ";
else
std::cout << " ";
std::cout << "\"" << what.captures(i)[j] << "\"";
}
std::cout << "}\n";
}
}
else
{
std::cout << "** No match found **\n";
}
}
int main(int , char* [])
{
print_captures("(([[:lower:]]+)|([[:upper:]]+))+", "aBBcccDDDDeeeeeee");
return 0;
}

boost::regex e("(\\d{3, 4})[- ]?(\\d{4)})[- ]?(\\d{4})[- ]?(\\d{4})");
//你的这个正则式有问题：括号不匹配
//所以在构造这个e的时候异常

#include <boost/regex.hpp> 
#include <iostream> 

void print_captures(const std::string& regx, const std::string& text)

楼主要学会用regex_test这样的工具先验证正则后再使用。

问题搞定， boost 库编译本身存在问题。
