Can't build with geometry.hpp in CLR project

[Sungjun4]

Visual Studio 2022(2019 as well) ISO C++ 14, 17, 20 boost: 1.84.0, 1.81.0

I create a new project, CLR class Library(.NET Framework) or CLR console App(.Net Framework), and install the Boost NuGet package(1.84.0)

And include the boost header, even not adding any source code, just including headers.

And build a solution.

Followings are no problem to build

include <boost/foreach.hpp>

include <boost/property_tree/ptree.hpp>

include <boost/property_tree/ptree_fwd.hpp>

include <boost/geometry/arithmetic/cross_product.hpp>

include <boost/geometry/geometries/geometries.hpp>

But if I add

include <boost/geometry.hpp>

Then I got the error.

Error C1189 #error: "This library now requires a C++11 or later compiler - this message was generated as a result of BOOST_NO_CXX11_REF_QUALIFIERS being set"

Is this a bug? or do I need any setting for using geometry.hpp in CLR?

It is OK with 1.76.0 but error from the 1.77.0

It seems that this error is generated by Boost.MultiPrecision: https://github.com/boostorg/multiprecision/blob/develop/include/boost/multiprecision/detail/check_cpp11_config.hpp#L33 becasue BOOST_NO_CXX11_REF_QUALIFIERS is defined in Boost.Config probably somewhere in this file: https://github.com/boostorg/config/blob/develop/include/boost/config/compiler/visualc.hpp This macro is set when

The compiler does not support ref-qualifiers on member functions as described in N2439.

(see documentation)

So the question is, does the compiler support ref-qualifiers for member functions? Here you can find some info and example code: https://akrzemi1.wordpress.com/2014/06/02/ref-qualifiers/ If it doesn't then the error is correct. If it does then it's a bug in Boost.Config and should rather be reported there.
