Fails to link when using clang compiler with MSVC or Clang on Windows

[tan-wei]

I create a simple C++ project to try Boost.Stacktrace.: main.cpp:

#include <iostream>

#define BOOST_STACKTRACE_LINK
#include <boost/stacktrace.hpp>

void bar() { std::cout << boost::stacktrace::stacktrace(); }

int main() { bar(); }

The project uses CMake to compile and link:

cmake_minimum_required(VERSION 3.15)

project(cpp_templates)

find_package(Boost 1.75.0 REQUIRED COMPONENTS stacktrace_windbg_cached)

if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS})
    link_directories(${Boost_LIBRARY_DIRS})
endif()

if(MSVC)
    add_compile_options(/std:c++17)
endif()

add_executable(c++_templates main.cpp)
message(STATUS "Boost: ${Boost_LIBRARIES}")
target_link_libraries(c++_templates ${Boost_LIBRARIES})

It will cause link error with Clang or MSVC:

[build] clang++: error: linker command failed with exit code 1 (use -v to see invocation)
[build] ninja: build stopped: subcommand failed.

The mismatch _ITERATOR_DEBUG_LEVEL leads the failure. The meaning of _ITERATOR_DEBUG_LEVEL is:

_ITERATOR_DEBUG_LEVEL = 0 (in release mode)
_ITERATOR_DEBUG_LEVEL = 1 (in release mode if _SECURE_SCL is defined)
_ITERATOR_DEBUG_LEVEL = 2 (in debug mode)

Why the debug version of library of Boost.Stacktrace, which is libboost_stacktrace_windbg_cached-clang11-mt-d-x64-1_75.lib, has the value of 0 with _ITERATOR_DEBUG_LEVEL? Is there anything wrong with my configure and build with Boost? I use the command to configure and build with Boost 1.75.0:

b2  install --build-type=complete toolset=clang

and

b2  install --build-type=complete toolset=msvc

Thanks very much.

AFAIK b2 does not define the _ITERATOR_DEBUG_LEVEL by default. You can define it with something like this b2 install toolset=clang define=_ITERATOR_DEBUG_LEVEL=1. If you want the _ITERATOR_DEBUG_LEVEL to be set by default, please report an issue in this repo https://github.com/boostorg/build/ and provide motivation.

This is not a stacktrace issue, closing.

Maybe I find the reason:

BOOST_STACKTRACE_USE_WINDBG should be predefined instead of BOOST_STACKTRACE_LINK.

BTW, thanks for your reply.
