[boost math] error: no operator "=" matches these operands in roots.hpp (297)

[tan@…]

I have just installed the Intel 14 C++ compiler and are now unable to build with boost math (everything was fine with previous Intel updates). Wish I can be more helpful but I have only the following error log to share (notice that I am not using the default policies though) ... and this is so even with revision 85588 trunk:

It looks to be OK with Intel 14 on Win32... this is in C++11 mode right? Can you try the reduced test case:

#include <tuple>

std::tuple<double, double> f()
{
   return std::make_tuple(1.0, 2.0);
}

int main()
{
   double a, b;
   std::tie(a, b) = f();
}

Thanks, John.

Update: I managed to get Intel-14 on Linux installed and the above test case compiles OK, but fails if you increase the tuple to 3 arguments. Filed as Intel issue 6000026407.

A workaround is to define BOOST_NO_CXX11_HDR_TUPLE - that's the fix I've committed to Boost.Config.

Dear John,

Thank you very much for locating the problem and putting out a workaround! And I am sorry to have made you work over the weekend! Thank you!

With best regards, HS

I've heard back from Intel - the test case works when Intel C++ 14 is on top of gcc-4.7.2 but not 4.6.

HTH, John.

Dear John,

Thank you very much for the information. I actually have another issue (see code below) using -std=c++11 on the non_central_chi_squared:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::math::evaluation_error> >'

what(): Error in function boost::math::tools::bracket_and_solve_root<e>: Unable to bracket root, last nearest value was 1.65974387253907228676e-331 Abort (core dumped)

which I built with Intel 13 and GCC 4.6.3:

icpc --version
icpc (ICC) 13.1.3 20130607

g++ --version
g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

The current trunk (revision 85656) also fails ... 5.39163355658688321214e+330 was the last nearest value though.

So I decided to go ahead and upgrade to Intel 14 (again) and the GCC toolchain (to 4.7):

icpc --version
icpc (ICC) 14.0.0 20130728

g++ --version
g++ (Ubuntu/Linaro 4.7.3-2ubuntu1~12.04) 4.7.3

I have no problem building my original case now. However, I am unable to link ... got this "undefined reference to `builtin_signbit'" message.

Interestingly, the example

#include <cstdio>
#include <boost/math/distributions.hpp>

int main()
{
   boost::math::non_central_chi_squared_distribution<>
      _dist( 3.0, 1.0 );

   std::printf( "  \nquantile(non_central_chi_squared(3,1),0.1) = %f\n",
         boost::math::quantile( _dist, 0.1 ) );

   return 0;
}

which gave me that runtime exception above, also fails to build with the same message: undefined reference to `builtin_signbit'.

Do you have any insight here? Maybe this is a problem with the Intel compiler again. :(

With best regards, HS

[John Maddock]

As the error message indicates it means Intel haven't implemented that GCC builtin yet. If you have an Intel support account, I suggest you file a bug report. Otherwise I might get around to it eventually....
