Here are couple more errors when parsing boost headers:
/opt/local/include/boost/unordered/detail/allocate.hpp:223: sorry,
unimplemented: call_expr cannot be mangled due to a defect in the C++ ABI
/opt/local/include/boost/unordered/detail/allocate.hpp:223: sorry,
unimplemented: call_expr cannot be mangled due to a defect in the C++ ABI
/opt/local/include/boost/math/constants/constants.hpp:90: sorry, unimplemented:
call_expr cannot be mangled due to a defect in the C++ ABI
This is Boost 1.56 on OS X 10.10. The first error corresponds to this code:
template <typename T, T Value>
struct integral_constant { enum { value = Value }; };
which looks pretty harmless to me. I keep hoping that there is some magic
combination of compile flags that will make everything just work. On OS X 10.9
I used llvm-gcc-4.2 to compile gccxml and as the compiler that gccxml would
simulate. This all worked with the latest clang and boost on 10.9.
Unfortunately, llvm-gcc-4.2 doesn’t compile on 10.10.
