提升错误,编译xtime.hpp时遇到问题

标签: boost compilation makefile

我一直在使用Boost开发一个C ++项目,在编译之间,我必须在boost中升级一些东西而没有任何意义,因为现在Boost依赖项无法编译:

有什么想法吗?我尝试将TIME_UTC更改为TIME_UTC_,因为这是我在其他网站上推荐的,但这似乎没有帮助。

编辑:Boost版本是版本:1.48.0.2。我在下面附上xtime:

编辑:为了说清楚,代码在导入boost / thread.hpp

时失败了

答案 0 :(得分:12)

对于那些遇到同样问题并努力在这里找到解决方案的人。 源自noodlebox的链接(https://svn.boost.org/trac/boost/ticket/6940):

您可以编辑/usr/include/boost/thread/xtime.hpp(或者您的xtime.hpp所在的位置) 并将所有出现的 TIME_UTC 更改为 TIME_UTC _ - 可能在第23和71行附近。

答案 1 :(得分:6)

如果您在使用Boost时遇到语法错误,则可能需要使用-std=c++11编译代码。

您可能已经阅读的TIME_UTC问题是使用c ++ 11的副作用。 TIME_UTC现在被定义为c ++ 11中的宏,因此您需要将TIME_UTC的所有实例替换为TIME_UTC_,或者只使用更新的(1.50.0+)已经修复过的Boost版本。

请参阅:https://svn.boost.org/trac/boost/ticket/6940

答案 2 :(得分:1)

由于您没有显示您的代码,我们只能猜测。我的猜测是你在代码中的某处定义了TIME_UTC宏。这个宏搞砸xtime.hpp标题。
