Hello Gregor, I am not sure if my last mail reached you. [1] There I did not notice a line for libboost_nowide in ldd output.
Also I tested by the last two modifications which made XS.so to be linked to libboost_nowide and made slic3r not fail with the unknown symbol error. Kind regards, Bernhard [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985473#20
