【问题描述】:
xcode 4.2
os x 10.7
当我将包含设置为如下所示时:
#include <iostream>
#include <boost/thread.hpp>
我从位于 /opt/local/include/boost/tr1/tr1 的文件中收到以下错误
Lexical or Preprocessor Issue
'boost/tr1/detail/config_all.hpp' file not found
/opt/local/include/boost/tr1/tr1/iostream 文件的内容:

# endif
# ifdef BOOST_TR1_NO_iostream_RECURSION

#endif
我应该使用位于 /Developer/SDKs/MacOSX10.7.sdk/usr/include/c++/4.2.1/ 的 iostream 标头
您必须原谅我,因为我对 c++ 非常陌生,对 xcode 更陌生。预先感谢您的任何帮助。
【问题讨论】:
-
您究竟做了什么来自定义包含路径,以便它首先在 /opt 中查找?
-
如果我在 boost 之前启动了我的包含路径,它会抛出各种错误。也许我需要取消递归搜索......
-
或者告诉它专门搜索我需要的 boost 的哪些部分,而不是所有的 boost。我只是担心如果我不包括所有的提升,它会破坏事情。我对此太陌生,无法确定。
