从1.69升级到1.82后Boost日志链接失败

Question

我有 boost 1.69，工作正常，我已将版本升级到 1.82，并且没有更改任何记录器设置或配置。 记录器现在无法与可执行文件链接。

我正在使用 boost 组件 - log 和 log_setup 两者配置正确并在

target_link_libraries

中使用。链接的库是 -

C:/vcpkg/installed/x64-windows/lib/boost_locale-vc140-mt.lib
debugC:/vcpkg/installed/x64-windows/debug/lib/boost_locale-vc140-mt-gd.lib

optimizedC:/vcpkg/installed/x64-windows/lib/boost_atomic-vc140-mt.lib
debugC:/vcpkg/installed/x64-windows/debug/lib/boost_atomic-vc140-mt-gd.lib

链接失败。示例-

set(BOOST_REQUIRED_VERSION 1.82.0)

set(BOOST_COMPONENTS locale filesystem log log_setup)

if (WITH_TESTS)
    set(BOOST_COMPONENTS ${BOOST_COMPONENTS} unit_test_framework)
endif()

find_package(Boost ${BOOST_REQUIRED_VERSION} REQUIRED COMPONENTS ${BOOST_COMPONENTS})

还有一个简单的例子 -

BOOST_AUTO_TEST_CASE(LoggingTest)
{
    init();
    logging::add_common_attributes();

    using namespace logging::trivial;
    src::severity_logger< severity_level > lg;

    BOOST_LOG_SEV(lg, trace) << "A trace severity message";
    BOOST_LOG_SEV(lg, debug) << "A debug severity message";
    BOOST_LOG_SEV(lg, info) << "An informational severity message";
    BOOST_LOG_SEV(lg, warning) << "A warning severity message";
    BOOST_LOG_SEV(lg, error) << "An error severity message";
    BOOST_LOG_SEV(lg, fatal) << "A fatal severity message";
}

Answer 1

通过添加正确的定义来实现正确的修复，如下所示 -

# Fix: error LNK2038: mismatch detected for 'boost_log_abi': value 'v2_mt_nt6' doesn't match value 'v2_mt_nt62'
add_definitions(-D_WIN32_WINNT=0x0602)
