Hi, The problem is with --std=c++11. I posted similar problem several years ago and kindly asked to state that asio builds with and without cxxflags="-std=c++11" create classes with different ABI. Add cxxflags="-std=c++11" to boost build. Enjoy, Slavek 2016-10-03 21:27 GMT+02:00 Stanley Friesen :

I managed to get the compiler options from the two builds. Other than -I options, there are few differences. None of them directly control structure packing. The PCL build has -fPIE (and also a matching -fPIC) and -DBOOST_DISABLE_ASSERTS. Our compile options include -mtune=<arch> (along with a matching -march), --std=c++11, -Dx86_64, and -g (though both have -O3 as well).

In typing this, it occurs to me the issue may be the --std=c++11. I will test that ASAP. (I already tested the -DBOOST_DISABLE_ASSERT to no effect).

Sigh. I thought so. I am having a dickens of a time getting libpcl to compile with the --std=c++11 flag. It seems that libvtk, used heavily by PCL, doesn't like C++11. (We can't compile our library without the flag since we actually use many C++11 features). I will continue to work on this.

Thanks, this discussion has at least pointed me in the direction I need to go.

​I have no problem compiling PCL 1.8.0 and VTK 7.0.0 with C++11 support . In the past VTK 6 (not sure on the exact version) and PCL 1.7.2 also worked fine. The VTK wiki seems to indicate VTK 6.1 is compatible with C++11 [1]. Maybe it is an issue with the compiler you're using. Some GCC versions had incomplete C++11 support iirc.

Hi, As far as I can remember, the complete problem with asio ABI compatibility sits in the asio/detail/atomic_count.hpp and the problem is different size of std::atomic<long> and boost::detail::atomic_count. You may probably use BOOST_ASIO_DISABLE_STD_ATOMIC option to make non c++11 ASIO and c++11 ASIO ABI compatible but I never tested it. We strictly use c++11.

-------------------- Quite right, as soon as I got VTK 7.0, the PCL library compiled fine (we only had 5.8 and 6.0 until earlier today). Now my problem is purely with our own library.

VTK 6.0 still had the issue in vtkMath.h where it used 'using namespace std' and then tried to call isinf or isnan. VTK7.0 correctly omits the using directive and calls std::isinf and std::isnan. It is possible this was actually fixed in 6.2 or 6.3.
