Building on i686 (nao vm 2.1.12) using boost-1.58 | segfaults in qi

[warp1337]

Hi,

I assume this is a special use case, however, maybe someone can give me a hint.

I successfully build libqi and libqi-python on Ubuntu 16.04 using qibuild and boost 1.58 (used @severin-lemaignan 's fork of libqi). I can do a

import qi

With no problem at all.

However, built on i686 (in the nao vm version 2.1.12) --- even after successful compilation of both libs, also using qibuild --- I get the following when trying the same in the VM...

I could spent another day on this, but maybe someone has an idea? Maybe @suryaambrose ?

Okay turns out it was the python version which has to be compiled using:

--enable-unicode=ucs4
