Package: libboost1.61-dev
Version: 1.61.0+dfsg-2.1
Severity: important
Dear Maintainer,
here is the simplest failing example I could create:
#include <boost/optional/optional_fwd.hpp>
#include <boost/optional.hpp>
int main() { return ; }
Compile like this:
clang++ -std=c++11 test.c
# OR
g++ -std=c++11 test.c
Expected behavior:
Compiles without error.
Actual behavior:
Does not compile.
First error from clang++:
In file included from test.cpp:2:

Apparently, the OpenBSD people have/had the same issue [1], which goes like
this:
(summary of link)
boost does not like mixing different compilers at build and run time.
Building boost with some gcc that doesn't support __int128 results in a
boost/config/user.hpp missing the "BOOST_HAS_INT128" define.
Then, boost/config/compiler/*.hpp re-enables it, but boost/config/suffix.hpp
doesn't catch wind of this.
Quick and dirty manual workaround:
echo '#undef __SIZEOF_INT128__' | sudo tee -a
/usr/include/boost/config/user.hpp
to enable it permanently.
I mark this as 'important', because this disrupts compilation for anyone using
forward-declarations, anywhere. Feel free to downgrade this report if it
doesn't.
Cheers,
Ben Wiederhake
