Tad added a patched version of bind/arg.hpp for affected versions since it
seems the fix isn't in 1.62.

I'll see if I can confirm the fix with Boost 1.62 soon.

Update of bug #25132 (project wesnoth):

  Status:None => Upstream Problem   

___

Follow-up Comment #5:

We reported this on boost https://svn.boost.org/trac/boost/ticket/12397 and it
will be fixed on next boost version (1.62 i think that is).

Until then the only known way to solve this issue is to eigher use another
boost version (boost 1.59 or eariler) or edit the boost files eigher by
removing 'BOOST_CONSTEXPR' or by applying the fix linked in the boost
bugreport.

Marking this as upstream problem which doesn't means that you shouldn't commit
a workaround if you find onw.

Follow-up Comment #4, bug #25132 (project wesnoth):

It still happens with gcc sometimes. One can simply remove the
'BOOST_CONSTEXPR' statement from the line above the static_assert and it works
fine.

Follow-up Comment #3, bug #25132 (project wesnoth):

In your ticket you wrote you have "boost 1.16.1", are you sure about that?
Boost 1.16 is from 2000, wesnoth requires boost 1.48.0 as can be read in the
INSTALL file.

I had similar problem with boost 1.60.0 though.

As you can see from the output you posted, the compilation failure happens in
boost and not wesnoth itself so this is actually a boost bug which happens to
affect wesnoth.

There were some changes made here:
https://github.com/boostorg/bind/commit/3c56630b5400c43d1a4393d685a407e68a69ce9e

Laster boost version might have this fixed.

The easiest solution might be to just compile with gcc or upgrade/downgrade
boost.

Update:

Forcing clang to use libc++ as stdlib also fails, but on a different file,
however.

Others have the same problem.

They solved this problem by hacking. Do we have a better solution?
