I am trying to run the available C code at GitHub for bloom filter (<https://github.com/jvirkki/libbloom>). When I try to compile I get an error: fcntl.h No such file or directory. I am using Ubuntu 16.04. I also check the path to locate fcntl.h, it's already there in the system (/usr/include/x86\_64-linux-gnu/bits/fcntl.h). So I do not know what can be the issue. I try to install essential packages too but it's not solving the problem.
