我有一个项目已经编译和链接几个月没有问题。最近将ubuntu升级到15.10将升级版本从1.55升级到1.58。现在突然间我得到了未定义的引用错误。无论我是否使用静态链接或动态链接，我都会收到错误：

boost 1.58中有什么不同之处我需要设置不同的编译标志吗？
答案 0 :(得分：3)
确保使用相同的编译器＆amp;编译所有。标志。
这意味着您需要清理构建并使用用于构建boost的打包版本的相同编译器（请注意，gcc也将作为dist-upgrade的一部分进行更新）。
对ABI或（隐式）预处理程序指令的任何更改都可能导致头文件发出不同（有效）声明，并违反ODR。
比获取链接器错误更糟糕的是，您可能实际上已经默默地获得了未定义的行为。
