我下载了http库 urdl ,试图从doc(http://think-async.com/Urdl/doc/html/urdl/getting_started/setting_options_to_perform_an_http_post.html)编译示例:
#define URDL_HEADER_ONLY 1
#include <boost/array.hpp>
#include <urdl/http.hpp>
#include <urdl/istream.hpp>
int main() {
urdl::istream is;
is.set_option(urdl::http::request_method("POST"));
is.set_option(urdl::http::request_content_type("text/plain"));
is.set_option(urdl::http::request_content("Hello, world!"));
is.open("http://somehost/path");
}
编译错误:
g:\boost\boost/asio/detail/handler_invoke_helpers.hpp(37) : error C2666: 'urdl::
detail::asio_handler_invoke' : 3 overloads have similar conversions
g:\urdl\include\urdl/detail/http_read_stream.hpp(488): could be 'void ur
dl::detail::asio_handler_invoke<Function>(const Function &,urdl::detail::http_re
ad_stream<Stream>::read_handler<Handler> *)' [found using argument-dependent loo

环境是Win7 + VS2010,任何想法?
感谢。

是的,你是对的,在新版本中,boost添加了一个名为foreach (string Tablename in uniqueFields)
{
List<string> TblName = Tablename;//here the problem
TblName = new List<string>();
Console.WriteLine("children of :" + TblName);
foreach (string TableAssociatedValue in fields)
{
if (TableAssociatedValue.Contains(Tablename.Trim()))
{
Console.WriteLine(TableAssociatedValue);
}
}
}
的模板函数,它与“http_read_stream.hpp(488)”中定义的函数冲突。解决方案是评论用户定义的函数。

在boost asio标题“handler_invoke_helpers.hpp”中更改:
using boost::asio::asio_handler_invoke;
asio_handler_invoke(function, boost::asio::detail::addressof(context));
到
boost::asio::asio_handler_invoke(function, boost::asio::detail::addressof(context));
这对我有用
