zig build with c library cannot reference windows api in target i386-windows-gnu

[codehz]

(and works in x86_64-windows-gnu/msvc)

the error is

(and more)

basically all windows apis referenced in c are failed to link...

but once I put my own testing c code, everything is working, so I can only repro this issue with iup library

background

I want to use iup library with zig, but I cannot use it binary release, due to some compatibility problems(yes, it doesn't even works in any windows target), so I decided to use source.

it is my build.zig
make sure iup's (3.30) source has been extracted in vendor/iup folder

const std = @import("std");
const Builder = std.build.Builder;

const IUPConfig = struct {
    target: std.zig.CrossTarget,
    name: []const u8,
    source: []const []const u8,
    includes: []const []const u8,
    defines: []const []const u8,

    fn getLibName(comptime self: @This()) []const u8 {
        return "iup" ++ self.name;
    }

    fn getBasePath(comptime self: @This()) []const u8 {
        return "vendor/iup/src" ++ self.name;
    }

    fn getArgs(comptime self: @This()) [self.defines.len + 1][]const u8 {
        var ret: [self.defines.len + 1][]const u8 = undefined;
        ret[0] = "-Wno-everything";
        inline for (self.defines) |def, i| {
            ret[i + 1] = "-D" ++ def;
        }
        return ret;
    }
};

fn buildIUPLib(b: *Builder, comptime info: IUPConfig) !*std.build.LibExeObjStep {
    const ret = b.addStaticLibrary(info.getLibName(), null);
    ret.setTarget(info.target);
    ret.addIncludeDir("vendor/iup/include");
    ret.linkLibC();
    comptime const basepath = info.getBasePath();
    ret.addIncludeDir(basepath);
    inline for (info.source) |rel| {
        const args = info.getArgs();
        ret.addCSourceFile(basepath ++ "/" ++ rel, &args);
    }
    inline for (info.includes) |rel| {
        ret.addIncludeDir(basepath ++ "/" ++ rel);
    }
    return ret;
}

This should be easy to fix, drop this file in lib/libc/mingw/lib32/ and it should compile just fine (send a PR if it does).

yes, it fix most of error...

but

lld: error: <root>: undefined symbol: _DllMainCRTStartup
lld: error: undefined symbol: __stack_chk_fail
lld: error: undefined symbol: __stack_chk_guard
lld: error: undefined symbol: sin
...

seems like crt symbols?

PS: there no dynamic library in the build script..

(maybe related to #6250

yes, I back to 58ee5f4 now it is working

@alexnask now the problem is related to stage-2 it break again in latest zig...
