Getting `erl_nif_api_funcs.h: error: undeclared here (not in a function)` when compiling in MinGW #233

Closed hochata closed 1 year ago

Hi!

I've been trying to compile under Windows using MinGW, but I can't get past this error.

$ MAKE=make mix compile

** (Mix) Could not compile with "make" (exit status: 2).

All the errors complain about undeclared objects in erl_nif_api_funcs.h.

This is my current installation

$ elixir --version
Erlang/OTP 25 [erts-13.1.4] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [jit:ns]

Elixir 1.14.3 (compiled with Erlang/OTP 25)

I'm not sure if it is a bug in Exqlite or I just haven't installed the right environment. I followed the instructions from Elixir Make to install an appropirate C toolchain.

Any idea about how to fix it? Or how could I debug it?

This sounds like an issue with your toolchain setup. @voltagex may be able to help out here.

Sorry, I used MSVC, not MinGW.

voltagex commented 1 year ago

Agree it seems like a toolchain problem, though.

hochata commented 1 year ago

Ok, I'll check my installation. Thanks for the tips!

warmwaffles commented 1 year ago

@hochata we added pre-compilation support now. You may not even need the full toolchain.

hochata commented 1 year ago

Mmm, it very likely will solve my problem. I will check it out. Thanks!

warmwaffles commented 1 year ago

No problem, feel free to comment if it does not.
