Function run [src]

This is a helper function to be called from build.zig scripts, not from inside step make() functions. If any errors occur, it fails the build with a helpful message.

Prototype

pub fn run(b: *Build, argv: []const []const u8) []u8

Parameters

b: *Buildargv: []const []const u8

Source

  pub fn run(b: *Build, argv: []const []const u8) []u8 {
    if (!process.can_spawn) {
        std.debug.print("unable to spawn the following command: cannot spawn child process\n{s}\n", .{
            try allocPrintCmd(b.allocator, null, argv),
        });
        process.exit(1);
    }

    var code: u8 = undefined;
    return b.runAllowFail(argv, &code, .Inherit) catch |err| {
        const printed_cmd = allocPrintCmd(b.allocator, null, argv) catch @panic("OOM");
        std.debug.print("unable to spawn the following command: {s}\n{s}\n", .{
            @errorName(err), printed_cmd,
        });
        process.exit(1);
    };
