Bug 520182 – >=dev-libs/boost-1.55 with sys-devel/clang-3.4 - ./boost/atomic/detail/gcc-atomic.hpp:961:64: error: no matching constructor for initialization of 'storage_type' (aka 'boost::atomics::detail::storage128_type')

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Fabio Scaccabarozzi 2014-08-18 14:49:32 UTC]

Boost library >=1.55 fails to build with clang-3.4.2 with the following error: no matching constructor for initialization of 'storage_type' (aka
      'boost::atomics::detail::storage128_type'), as reported in the upstream bug in the URL field.

Reproducible: Always

Steps to Reproduce:
1. CC="clang" CXX="clang++" emerge -1 =dev-libs/boost:1.55.0 (both -r1 and -r2)
2.
3.
Actual Results:  
Compilation fails.

Expected Results:  
Compilation should succeed.

Applying the two patches from URL comment#8 makes the compilation succeed.
The issue has already been marked "resolved" upstream.
Backporting the patches to previous versions is unnecessary, as they all compile fine without them.
Compilation correctly succeeds with GCC 4.8.3 as well.
The error is due to clang not supporting 128 bit integers.
As stated in the upstream bug, the issue should NOT be visibile on x86, but only on amd64.

[Comment 1 Sergey Popov 2014-12-17 11:26:01 UTC]

Can not reproduce this with sys-devel/clang-3.4.2 and dev-libs/boost-1.55.0-r2 in clean chroot on stable amd64

As there was no attached build.log, i will close this as WORKSFORME
