Failed to build: error: ‘uint64_t’ was not declared in this scope

[knewter]

Not really sure the culprit, felt obligated to report the build failure. happy to help sort it out if i can, i'm sure it's just something janky on my end

# mix.exs
  defp deps do
    [
      {:hnswlib, github: "elixir-nx/hnswlib"},
    ]
  end

Error happened while installing hnswlib from precompiled binary: "missing checksum.exs file".

You need to have gcc and make installed. If you are using
Ubuntu or any other Debian-based system, install the packages
"build-essential". Also install "erlang-dev" package if not
included in your Erlang/OTP version. If you're on Fedora, run
"dnf group install 'Development Tools'".

From the initial config messages it seems that the C/C++ compilers aren't set properly. Did you ensure gcc/g++ are properly installed and set as the default compilers?

Hi @knewter, I've push a commit that includes the stdint.h header to fix this issue. It should work now, please let me know if it doesn't!

v0.1.5 is shipped!
