NIF compilation error on FreeBSD

[nicocaille]

When trying to compile this package (as a dependency) getting the following error:

==> siphash
could not compile dependency :siphash, "mix compile" failed. You can recompile this dependency with "mix deps.compile siphash", update it with "mix deps.update siphash" or clean it with "mix deps.clean siphash"
** (MatchError) no match of right hand side value: {"make: \"/usr/local/xiloc/analytics/deps/siphash/Makefile\" line 5: Missing dependency operator\nmake: \"/usr/local/xiloc/analytics/deps/siphash/Makefile\" line 11: Need an operator\nmake: Fatal errors encountered -- cannot continue\nmake: stopped in /usr/local/xiloc/analytics/deps/siphash\n", 1}

I managed to get rid of the error by disabling the NIF via putting the following lines in my config.exs:

config :siphash,
  disable_nifs: true

The server is running: FreeBSD 12.2-RELEASE-p6 GENERIC amd64 with the following Elixir/Erlang versions:

elixir          1.11.4-otp-23
erlang          23.3.1

Thanks for your help

Correct solution is to modify mix.exs to have it call gmake instead of make:

diff --git a/mix.exs b/mix.exs
index b19cdef..4df56e7 100644

the patch @feld suggests works for me and solves a compile problem i have on FreeBSD. This is used as a dependency in https://github.com/plausible/analytics and stops it from compiling on FreeBSD
