Can't get cImport to work at all

[inner sluice]

i have a really simple pair of files, main.zig and something.h w/ a single struct definition in the .h file and then trying to use that struct in .zig but the compiler keeps telling me "file not found" even though when i look in zig-out i can clearly see that it's compiling the .h file.

both files are in src/ and i don't know if that's a problem.
don't know if it's relevant, but i'm using windows -- for all i know it doesn't work on windows yet, but i didn't see anything in the docs saying so it's probably something i'm doing wrong

main.zig

const std = @import("std");
const something = @cImport({ @cInclude("src/something.h"); });

pub fn main() !void {
    var s: something.something = .{ .a = 1, .b = 2, .c = 3, };
    _ = s.a + s.b;
}

something.h

struct something {
    int a;
    int b;
    int c;
};

i have also added the following to build.zig

    exe.addIncludePath("src");
    exe.addCSourceFile("src/something.h", &[_][]const u8 {});
    exe.linkLibC();

so far i can only get it to give me 2 errors

1. error: C import failed with no other details
2. if i remove the src/ from the @cInclude statement, it tells me file not found

probably worth mentioning i'm using the master build of the compiler (installed today) after trying it on 0.10. results not different on either

try removing the addCSourceFile call

(probably shouldn't be trying to compile a header file in the first place regardless of if that fixes it)

In theory the second solution you mentioned should work

[noble loom]

isn't addCSourceFile for .c files?

ye

'course, some C compilers can emit Pre-Compiled Headers (PCHs), but I don't think that's a first class citizen of the build system

welp, when i pulled that line from google, it sounded sus because what if you need to include like a thousand of them lol

anyway that worked thank you gents

i really just thought... actuially i don't even know what i thought now that i'm looking at it again w/out that line. it seems so obvious that all i'd need is addIncludePath

aye, sometimes all it takes is another brain or two

reasoning and logic is a social skill, in a weird way

it very much is

i'm using words to talk to a computer lol it must be
