[Nfd-dev] trouble building ndn-cxx on Raspberry Pi

[Junxiao Shi]

Hi Anthony

This may have something to do with the changed std::string ABI in GCC5.
When Boost is compiled with GCC and ndn-cxx is compiled with Clang, there
is an ABI mismatch, causing the linker error.
The standard solution would be recompiling Boost with Clang. But compiling
Boost on a Pi would take very long time.

I've CC'ed Davide our compiler expert, to see if he knows something about
this ABI problem.

Yours, Junxiao
