There's a Qt5 moc error when using Boost, with a work-around. See:
http://qt-project.org/forums/viewthread/22993
It describes "Boost 1.49", but this work-around also works for "Boost 1.52":
...leads to compile error (Win7/MSVS2010):
C:/Some/Path/3rd/Boost/boost_1_52_0/boost/mpl/if.hpp(131): Error: Macro
argument mismatch.
Project : error PRJ0019: A tool returned an error code from "MOC
..\..\Some\Path\MyClass.hpp"
Work-around, in ALL files that "moc":
//...USING BOOST, MUST GUARD INCLUSION...
#ifndef Q_MOC_RUN
# include <boost/function.hpp>
# include "MyClass.hpp"
#endif // Q_MOC_RUN
We're not using much of Boost 1.52, but we *do* use some of the
"type/traits" stuff (which triggers this error).
There are a few "Boost/moc" errors/bugs reported in
https://bugreports.qt-project.org/, but I couldn't find this one. Did I
miss it, or should I create a new one?
I'm specifically curious about when this might be fixed, as the work-around
is annoying (I haven't looked into what the fix might be).
Thanks!

I have boost 1.50 here and I cannot reproduce the issue.
Please open a new bug report and if possible, a small test-case that does not
depends on boost.
Try to copy all the involved macro in a file.
I have maybe the same/similiar error (qt5.0, boost 1.52). After
including
#include<boost/uuid/uuid.hpp>
#include <boost/uuid/random_generator.hpp>
in a qt-header file, I get the error
boost/mpl/if.hpp(131): Error: Macro argument mismatch.
during compiling of the correspondence moc_...cpp file. It looks like
a preprocessor error message...
Could you please file a bug report in Jira for this? Ideally with a
test case (and the exact boost version).
moc is now (since 5.0) parsing preprocessor statements (which fixes
many other bugs). I thought I had all problems fixed, but boost
headers are extremely evil with macros.
Thanks,
Lars
Cheers

I created https://bugreports.qt-project.org/browse/QTBUG-29331.
I have this issue with boost 1.50 and 1.52 on win7 with msvc2010.
Hopefully this is enough. I attached my a small test project. I really
don't know how to create a suitable test case...
regards
jan
