Fetch and install dependencies? [Yn] Y
* running mix deps.get
Your Nerves project was created successfully.

You should now pick a target. See https://hexdocs.pm/nerves/targets.html#content
for supported targets. If your target is on the list, set `MIX_TARGET`
to its tag name:

For example, for the Raspberry Pi 3 you can either
  $ export MIX_TARGET=rpi3
Or prefix `mix` commands like the following:
  $ MIX_TARGET=rpi3 mix firmware

If you will be using a custom system, update the `mix.exs`
dependencies to point to desired system's package.

Now download the dependencies and build a firmware archive:
  $ cd dht_test
  $ mix deps.get
  $ mix firmware

If your target boots up using an SDCard (like the Raspberry Pi 3),
then insert an SDCard into a reader on your computer and run:
  $ mix firmware.burn

Plug the SDCard into the target and power it up. See target documentation
above for more information and other targets.

This file was compiled for the host or a different target and probably
will not work.

Check the following:

1. Are you using a path dependency in your mix deps? If so, run
   'mix clean' in that directory to avoid pulling in any of its
   build products.

2. Did you recently upgrade to Elixir 1.9 or Nerves 1.5?
   Nerves 1.5 adds support for Elixir 1.9 Releases and requires
   you to either add an Elixir 1.9 Release configuration or add
   Distillery as a dependency. Without this, the OTP binaries
   for your build machine will get included incorrectly and cause
   this error. See
   https://hexdocs.pm/nerves/updating-projects.html#updating-from-v1-4-to-v1-5

3. Did you recently upgrade or change your Nerves system? If so,
   try cleaning and rebuilding this project and its deps.

4. Are you building outside of Nerves' mix integration? If so,
   make sure that you've sourced 'nerves-env.sh'.

If you're still having trouble, please file an issue on Github
at https://github.com/nerves-project/nerves_system_br/issues.

I had a similar error on an existing project where I was trying to rebuild using your release instead of jjcarsten's fork. I got this:

** (Mix) Could not compile with "make" (exit status: 2).
You need to have gcc and make installed. Try running the
commands "gcc --version" and / or "make --version". If these programs
are not installed, you will be prompted to install them.

let me know if you have any questions. one of the core nerves guys told me this on slack FWIW:

It looks like nerves_dht leaves its output in the main source directory (not under _build). This has started causing a lot of issues and we’ve been fixing projects over the past year to avoid this. Building clean is somewhat of a workaround

Apparently this is an issue for elixir-ls in vscode. jjcarlsen helped me:

Then I shutdown vscode.

then I did this:

rm -Rf .elixir-ls/ _build/ deps/
mix deps.get
mix deps.compile
mix mix firmware

All was right in the world. However, the nerves community recommends you build the C binaries in the _build directory as that is what is adding to the issue.

I have this same bug when I compile for different devices, I am not sure why deps doesn't recompile well, I have same issue with sqlite_ecto2 lib when change my MIX_TARGET.

You need remove the deps and recompile again
