Eclipse CDT条件编译？

Question

I have a line of code that Eclipse CDT (Oxygen) code fails to recognise. I'm pretty sure the code is perfectly fine. It compiles OK but I still like project without red squiggles on them.

How can I tell Eclipse ignore this line? I imagine I would enclose it in conditional compilation directives that only affect code checking but not normal compilation. Something like this:

#ifdef _ECLIPSE_CODE_CHECKER
    my_bad_code();
#endif

But I cannot find any such macro predefined by Eclipse.

It would be even better to make the code checker simply accept this line.

Here's the smallish example:

#include <boost/log/core.hpp>
#include <boost/log/expressions.hpp>
#include <boost/log/support/date_time.hpp>
#include <boost/log/utility/setup/file.hpp>
#include <boost/log/utility/setup/common_attributes.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>

namespace logging = boost::log;
namespace expr = boost::log::expressions;
namespace bpt = boost::posix_time;


int main()
{
  logging::add_file_log(
   logging::keywords::file_name ="file.log",
   logging::keywords::format =
    (expr::stream << expr::format_date_time<bpt::ptime >("T:", "%H:%M:%S") << expr::smessage));    
}

Eclipse complains about add_file_log having invalid arguments. Removing format_date_time makes the error go away.

The macro you're looking for exists and is called __CDT_PARSER__ :

#ifdef __CDT_PARSER__
    my_bad_code();
#endif

As for Eclipse's code checker accepting the line, I would encourage you to file a CDT bug .
