What is the code that fails? Is this a regression, that is, did this same code work with an earlier version of Boost?

From a clean build this is the output, hopefully if gives you the information you are after? `------ Rebuild All started: Project: Process Control Service Group, Configuration: Debug Win32 ------ Recording build details "Built: 06/08/2020 12:50:17 (HW-WOP-113835:U49100)"

This doesn't really answer any of my questions, but I can now see what's the reason for the error - the placeholder _1 refers to the standard std::placeholders::_1, rather than to the Boost one, boost::placeholders::_1.

Excellent, thank you, no more problem.

Sorry, hate to tag on to another post but I get a similar error with boost 1.7.5. Here's my Visual Studio error train:

[pdimov]

The cause of the error is the same: you're passing the standard _1 from namespace std::placeholders to boost::bind.

1>            _Fn=boost::_bi::bind_t<void,boost::_mfi::mf0<void,plasticity::fem::NodeStatic>,boost::_bi::list1<boost::_bi::value<std::_Ph<1>>>>,

I suppose I need to just make this work.

[SSStevePye]

Thank you. I was trying to build some software we got from a 3rd party. I got past the compile errors only to get into boost library linking issues. There's some magic happening where Visual Studio knows the names of the boost libraries (including boost version) without me telling it. I think I will throw the project back over the wall and concede defeat.

The cause of the error is the same: you're passing the standard _1 from namespace std::placeholders to boost::bind.

1> _Fn=boost::_bi::bind_t<void,boost::_mfi::mf0<void,plasticity::fem::NodeStati c>,boost::_bi::list1<boost::_bi::value<std::_Ph<1>>>>,

I suppose I need to just make this work.

The autolink magic is documented here: https://www.boost.org/doc/libs/1_75_0/libs/config/doc/html/boost_config/boost_macro_reference.html#boost_config.boost_macro_reference.macros_for_libraries_with_separate_source_code.automatic_library_selection

In particular, defining BOOST_ALL_NO_LIB disables it.

Added support for using the standard placeholders in https://github.com/boostorg/bind/commit/c85b31e3d200dda2a73cf0027a82c6d8e29066f8.

Sorry to bother you. @pdimov

I encountered the same issue. In the past comment, you said can pass the standard _1 from namespace std::placeholders to boost::bind.

Could you tell me where could I change Define namespace ?

I tried to declare the namespace in bind.hpp, but it still showed the error.

Thanks for your reading.

What code are you trying to compile, and what are the errors you are getting?
