both builds to work

Diff permalink nektro/zigmod@9d8f820...829e469

[alexrp]

Just to be clear, the correct triple is mips64-linux-muslabi64 (this changed in 0.14.0 to make clear the distinction between muslabi64 and muslabin32). Do you hit the same issues with that as well?

[nektro]

muslabi64 succeeds

[alexrp]

Ok, then I think there's no bug here, at least as far as actual compilation goes.

It is fairly odd that the compiler didn't fail with:

zig/src/main.zig

Lines 3616 to 3618 in 9a3540d

	error.LibCUnavailable => {
	const triple_name = try target.zigTriple(arena);
	std.log.err("unable to find or provide libc for target '{s}'", .{triple_name});

Need to see what's up with that.

Anyway:

It is fairly odd that the compiler didn't fail with:

This is because a static library is being built, so libc isn't actually being linked. I don't think there's anything particularly great we can do to diagnose this situation right now. #20690 will improve the situation significantly.

That being said, the error about -fno-PIC and -mabicalls does actually indicate a bug in zig cc that will mainly affect compilation for freestanding.

Building the branch you indicated with just zig build and Zig 0.14.0 gets me:

if you cherry-pick nektro/zigmod@71a068a it should reproduce again, apologies

Fixing this is blocked by llvm/llvm-project#142060.
