Really? Change the host's header files? Sounds crude.

sorry, I don't get past this error on my system:

  Build dependency: Please install the GNU C Compiler (gcc) 4.8 or later \
    gcc -dumpversion | grep -E '^(4\.[8-9]|[5-9]\.?)'
  Build dependency: Please install the GNU C++ Compiler (g++) 4.8 or later \
    gcc -dumpversion | grep -E '^(4\.[8-9]|[5-9]\.?)'

  Prerequisite check failed. Use FORCE=1 to override.

Passing the suggested FORCE=1 doesn't help either.

Looking at the 'README.md' file, it seems that compiling on any arbitrary
Linux system is not the preferred way:

  There are two preferred ways to use the buildsystem:

  1. Using the `onion/omega2-source` Docker image **Recommended method**
  2. Running the build system on a Linux system

Compiling via docker as described in that README.md works here as expected.

The terminal output of the failed build doesn't tell us too much.
Please look into 'config.log'.

I didn't look deeper in the scripting around the plain findutils build,
but as I can't reproduce the error, and given that the building is not quite
standard, I guess you could get better help from the people/distribution
who maintain OnionIoT.

Finally, findutils-4.6.0 is from Dec 2015.  I suggest updating to 4.8.0 instead.

Have a nice day,
