Compilation error 1.2 on Ubuntu 14.04

Hi,

Using gcc 4.8.2 I first ran

cmake -DPYTHON_LIBRARY=/usr/lib/python2.7/config-x86_64-linux-gnu/libpython2.7.so ../src_triqs1.2

without problems. Subsequently, however, "make" stopped with the following error:

Anyone seen this before?

Cheers,

Strange. Are you on 32 bits machine by any chance ? size_t is unsigned int ?
