Need help in installation

[Fyphia]

Hi,
I'm tring to run "make" command in /nim-falcon/repos/msgpack4nim/
But I get this error:

make: *** [fc_rr_hctg_track2.exe] Error 1

My python version is python/2.7.13-venv.

What should I do to solve this issue?
Thanks a lot!

looks like nim-falcon use outdated msgpack4nim. both Nim and msgpack4nim undergo many changes recently.
didn't the nim-falcon specifically says you should run git submodule update --init --recursive?
you can also download latest msgpack4nim from github and manually copy msgpack4nim.nim to your project subdir.
