下面是我已经能够淘净了几个小时后，找到***的解决方法。这基本上是其他人一直在说，但有一些澄清。

• 的问题与moc.exe做不正确处理升压宏。


• 在为了解决这个问题，我们通过定义包括对moc.exe过程中后卫，但不是经常源代码编译禁止包含升压头。



• 这可以通过添加以下code到项目文件（例如myproject.pro）最容易实现的

   ＃确保QMAKE_MOC包含商务部可执行文件路径
  负载（MOC）＃每个Boost头文件包括你...
  QMAKE_MOC + = -DBOOST_INCLUDE_GUARD_GOES_HERE
   

例如，如果我想使用的日志库，我有：

 的#include＆LT;升压/日志/ trivial.hpp＆GT;
 

如果我打开了头文件，我可以在上面看到，包括后卫被命名为 BOOST_LOG_TRIVIAL_HPP_INCLUDED _ 。因此，在.pro文件中相应的行内容如下：

  QMAKE_MOC + = -DBOOST_LOG_TRIVIAL_HPP_INCLUDED_
 

如果一对夫妇的更多音符他们相关的人：

• 如果你觉得这不工作，确保运行的qmake和重建项目，只要你添加一个新行到您的项目文件。


• 我使用的Windows 7 32位使用Qt 5.0.1升压1.53和建设中QtCreator MSVC2010。

In qt 4.8 I used boost (1.52) It all was ok... Now I try to move to QT5 and get if.hpp: Macro argument mismatch error on line 131 BOOST_MPL_AUX_NA_SPEC(3, if_). In some QT forums there is presented a solution like this:

#ifndef Q_MOC_RUN
// All boost includes
#endif // Q_MOC_RUN

in each my file that uses boost... So question here is - how to tell to boost that QT is not ready for BOOST_MPL_AUX_NA_SPEC and that boost shall use some more primitive preprocessor syntax one that would be QT5 compatible?

Update: found this solution yet it seems not to bring any effect at all in Qt5=(

Here is the best workaround I've been able to find after scouring the net for a few hours. It is basically what other folks have been saying, but with a few clarifications.

• The problem has to do with moc.exe not correctly handling Boost macros.
• In order to get around this, we disable inclusion of Boost headers by defining their include guards for the moc.exe process, but not for regular source compilation.

• This can be accomplished most easily by adding the following code to your project file (e.g. myproject.pro):

  # ensure QMAKE_MOC contains the moc executable path
  load(moc) 
  
  # for each Boost header you include...
  QMAKE_MOC += -DBOOST_INCLUDE_GUARD_GOES_HERE 
  

For example, if I want to use the logging library, I'd have:

#include <boost/log/trivial.hpp>

If I open up the header file, I can see at the top that the include guard is named BOOST_LOG_TRIVIAL_HPP_INCLUDED_. Therefore, the corresponding line in the .pro file would read:

QMAKE_MOC += -DBOOST_LOG_TRIVIAL_HPP_INCLUDED_

A couple of more notes in case they are relevant for anyone:

• If you find this not working, make sure to run qmake and rebuild your project whenever you add a new line to your project file.
• I'm using Boost 1.53 with Qt 5.0.1 and building for MSVC2010 within QtCreator on Windows 7 32-bit.
