I’m trying to learn zig and I wanted to test a single function for learning purposes even though it’s not really required I wanted to know that its doing what I expected
const std = @import("std");
const c = @cImport(@cInclude("include/miniaudio.h"));
const Playlist = struct {
songs: std.ArrayList([]const u8), // Dynamic array for song file paths
current_index: usize, // Current song index
paused: bool, // Flag to check if the song is paused
context: c.ma_context, // Miniaudio context
device: c.ma_device, // Miniaudio device for audio playback
sound: c.ma_sound, // Miniaudio sound
};
// Initialise the playlist with default values
fn initPlaylist() Playlist {
return Playlist{
.song = std.ArrayList([]const u8).init(std.heap.page_allocator),
.current_index = 0,
.paused = false,
.context = undefined,
.device = undefined,
.sound = undefined,
};
}
test "test initPlaylist" {
var playlist = initPlaylist();
const expect = std.testing.expect;
// Check that the songs array is initialised and empty
try expect(playlist.songs.items.len == 0);
// Check the current index is initialised and 0
try expect(playlist.current_index == 0);
// Check the paused flag is initialised and false
try expect(playlist.paused == false);
// Check that the context is initialized to undefined
try expect(playlist.context == undefined);
// Check that the device is initialized to undefined
try expect(playlist.device == undefined);
// Check that the sound is initialized to undefined
try expect(playlist.sound == undefined);
// Clean up to prevent a memory leak
playlist.songs.deinit();
}
Note I’ve tried the following
const c = @cImport({
@cInclude("include/miniaudio.h");
});
And
const c = @cImport({
@cInclude("miniaudio.h");
});
I keep getting the same error

zig env

"zig_exe": "/usr/bin/zig",
"lib_dir": "/usr/lib/zig",

"global_cache_dir": "~/.cache/zig",
"version": "0.10.1",
"target": "x86_64-linux.6.6.31...6.6.31-gnu.2.39"
After actually looking at the output of zig env I’m wondering is this because of the version of zig installed?
I am happy to grab the latest version and try again, but that isn’t going to help my understanding of why this error is happening.
Thank you.
