Basically, boost does not like mixing different compilers at build
and run time.
We build boost with gcc-4.2.1, which doesn't support __int128.
$ /usr/local/bin/egcc -dM -E - < /dev/null | grep SIZEOF_INT128
#define __SIZEOF_INT128__ 16
$ /usr/bin/cc -dM -E - < /dev/null | grep SIZEOF_INT128
$
This results in a /usr/local/include/boost/config/user.hpp missing
the "BOOST_HAS_INT128" define.
When building something which depends on boost using a newer compiler
(gcc-4.9, clang), the following happens:
the code snippet from /usr/local/include/boost/config/compiler/{clang,gcc}.hpp
---8<---
#if defined(__SIZEOF_INT128__) && !defined(__CUDACC__)
# define BOOST_HAS_INT128
#endif
---8<---
reactivates __int128 support.
But the code into /usr/local/include/boost/config/suffix.hpp:
---8<---
#if defined(BOOST_HAS_INT128) && defined(__cplusplus)
namespace boost{
# ifdef __GNUC__
__extension__ typedef __int128 int128_type;
__extension__ typedef unsigned __int128 uint128_type;
# else
typedef __int128 int128_type;
typedef unsigned __int128 uint128_type;
# endif
}
#endif
---8<---
is never reached, because /usr/local/include/boost/config/user.hpp
lacks "#define BOOST_HAS_INT128".
And thus the big boom below:
