Dear Matthew,
It's definitely a linker problem.
Is it possible that you have different versions of compiler, linker and
FLUKA?
In different versions i mean 64 bit compiler and 32 bit linker or
something like multilib version.
Because in log file there are lines:
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-unknown-linux-gnu/4.9.2/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with:/build/gcc/src/gcc-4.9-20150304/configure --prefix=/usr --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man --infodir=/usr/share/info
and /usr/lib directory is usually for 32 bits version.
Best regards,
Mikhail
