Error compiling from source

I checked out from Github and my current revision is
4bab7afaa4943bb627c25ec4e55e383c39dd14bd

I'm on Ubuntu 16.04 and make stops with the following error:

g++ -DHAVE_CONFIG_H -I.    -include ./config.h -I./src -I./src -I./src/FbTk
-I./nls -std=c++0x  -g -O2  -MT src/fluxbox-cli_cfiles.o -MD -MP -MF
src/.deps/fluxbox-cli_cfiles.Tpo -c -o src/fluxbox-cli_cfiles.o `test -f
'src/cli_cfiles.cc' || echo './'`src/cli_cfiles.cc

$ git status shows the repo up to date. Am I missing some dependency or is
this dependent on some compiler version?
