我正在尝试使用 scons 将我的项目编译为共享库。我使用的是 Windows 7 和 Visual Studio 2013 RC。在项目中，我使用的是 boost。
该项目编译良好。但是，当它尝试链接时，我得到以下信息：
scons: warning: No version of Visual Studio compiler found - C/C++ compilers most likely not set correctly

我很好奇为什么它试图链接到libboost_log-vc110-mt-1_54.lib而不是libboost_log-vc120-mt-1_54.lib，这是我在链接命令中指定的。此外，据我所知，vcxxx编译器标签 boost 用于告诉编译器的哪个版本构建了 boost 库......所以它几乎就像scons认为 boost 是使用 Visual Studio 2012 构建的，这将是vc110......我'我不确定。
