c++ - Visual Studio 2013 Boost-log v1_61_0 链接错误

Question

我尝试使用简单的 boost.asio daytime6 教程文件，效果很好并添加 boost.log 简单记录器，取自 settings_file 示例代码如下所示:

根据这个线程:
Boost-log linker error
我确实检查了它是否设置为 Yes (/Zc:wchar_t)，它的确如此。

但我仍然收到那些链接错误:

Answer 1

我怀疑您的 Boost 是为 Windows Vista 和更高版本构建的，而您正在为 Windows XP 构建代码。因此，Boost.Log 符号在库二进制文件和您的目标文件中的处理方式不同。

要为 Windows XP 构建 Boost，您需要在构建 Boost 时将 define=BOOST_USE_WINAPI_VERSION=0x0501 添加到 b2 命令行，并在构建您的系统时类似地定义此宏代码也是如此。
