 This is LuaTeX, Version 1.0.4 (TeX Live 2017/dev)
hm why luatex 1.0.4 ?
I expected that mtxrun installed luatex 1.0.3

ok, now if you call one function you should see

The ffi module is available for:\n"

    archictures       : ARCH_X86 and ARCH_X64,\n"
    operating systems : OS_CE, OS_WIN, OS_LINUX, OS_BSD and OS_POSIX

The ARM processor is currently not supported. There are subtle
differences between this module and the one in luajitTeX
and we hope to be in sync around TeXLive 2018.
Different OS can have different interfaces,
for instance OS_WIN has not 'complex.h'. If you want portable
code, stick to the most common concepts.
