Android link error when linking PIC compiled static zig library into shared library

[Beyley]

Zig Version

0.14.0-dev.2050+4adf63aef

Steps to Reproduce and Observed Behavior

Clone libsce on commit b7e30492a934cb390743fd5e3b286a903caae352

Run zig build publish_libsce -Doptimize=Debug with android NDK 21 installed (if you can't install that specific version, you can override the version using -Dndk_version=XX)
All builds will succeed except for the Android builds, which fail in Debug or ReleaseSafe configurations.

This failure is linked to my libc polyfill library, which is a Zig static library I link into the final executable. These polyfills aren't distinctly required on android, only on platforms like Linux where I do not link libc. However, this should still work nonetheless.

This issue seems to have been talked about in the past here, however no dedicated issue for -fPIC not taking effect was ever opened tmk.

Expected Behavior

Compilation succeeds, as the static zig library is compiled with -fPIC (if you run zig build publish_libsce -Doptimize=Debug --verbose, you'll see that they are compiled with -fPIC, but that doesn't seem to work correctly in this case for some reason.)

readelf.txt

[alexrp]

Yeah, the relocations in libc_polyfill.a look distinctly non-dynamic. Just to rule out the obvious, have you verified that -fPIC actually gets passed by the build system to the compiler when creating it?

recompiling like mentioned in this other thread #17575 (comment) got me unblocked on this same issue

[alexrp]

I did some digging into PIC/PIE; the error here actually totally makes sense. When you build a static library for Android, it gets built as PIE by default due to:

zig/src/target.zig

Lines 46 to 48 in e28b402

	pub fn requiresPIE(target: std.Target) bool {
	return target.abi.isAndroid() or target.os.tag.isDarwin() or target.os.tag == .openbsd;
	}

zig/src/Compilation/Config.zig

Lines 417 to 435 in e28b402

	const pie: bool = b: {
	switch (options.output_mode) {
	.Obj, .Exe => {},
	.Lib => if (link_mode == .dynamic) {
	if (options.pie == true) return error.DynamicLibraryPrecludesPie;
	break :b false;
	},
	}
	if (target_util.requiresPIE(target)) {
	if (options.pie == false) return error.TargetRequiresPie;
	break :b true;
	}
	if (options.any_sanitize_thread) {
	if (options.pie == false) return error.SanitizeThreadRequiresPie;
	break :b true;
	}
	if (options.pie) |pie| break :b pie;
	break :b false;
	};

But you cannot put PIE objects into a shared library! It may happen to work when no thread-local variables are in play, but it's still basically UB.

The important thing here is that Android 5.0+ requires PIE for dynamically-linked executables. However, that does not necessarily mean that we need to build objects or static libraries as PIE. And it certainly does not mean that we should outright block building them as non-PIE. You can link PIC-but-not-PIE objects into a PIE executable just fine.

@Beyley @nuxusr @silbinarywolf can you test this compiler patch in your projects?
