Force all native libraries to be statically linked when linking a static binary #111698

Amanieu · 2023-05-17T21:58:32Z

Previously, #[link] without an explicit kind = "static" would confuse the linker and end up producing a dynamically linked library because of the -Bdynamic flag. However this binary would not work correctly anyways since it was linked with startup code for a static binary.

This PR solves this by forcing all native libraries to be statically linked when the output is a static binary that cannot link to dynamic libraries anyways.

Fixes #108878
Fixes #102993

I'm not entirely sure how to test this.

Given the original issue at hand here, I don't expect that I'll be able to use the nightly compiler to compile this branch.

I tried anyway, but:

This makes me wonder: how are official binaries produced if the upstream binaries aren't linking libraries properly? Is some non-default flag used when building these?

I guess I need to explicitly tell the nightly compiler to dynamically link to libc, right? Or statically link all external libraries?

nekopsykose · 2023-05-18T11:50:15Z

@WhyNotHugo that looks unrelated, i would assume you get that issue building the compiler without these changes. you'll have to figure out how to do that first

after:

first, building without a .a available fails (good):

adding the .a:

I need to look at what this PR does in detail, probably next week.
There's some history behind these issues #71647, #39998, maybe #71651.

Amanieu · 2023-05-18T21:50:27Z

A static binary literally cannot link to dynamic libraries. The only sane behavior here is to force all external libraries to also be statically linked or to emit an error.

petrochenkov · 2023-05-29T19:18:53Z

A static binary ...

First, -C target-feature=+crt-static is more like "link libc statically" which is very similar to "make a static binary" on Unix-like targets, but e.g. on Windows you can link libc statically and still link to other DLLs because dynamic linker is an OS component and not libc component in that case.

... literally cannot link to dynamic libraries

Second, this is true for ELFs loaded by standard dynamic linker, but not necessarily true for ELF plugins loaded by something else.

For example, unix style linkers not being opinionated in this regard make it very convenient to make statically linked DynamoRIO plugins (with which you are probably familiar due to your work on MAMBO) that still link to libdynamorio.so dynamically at static link time and are loaded by that same libdynamorio.so instead of a standard ld.so.

petrochenkov · 2023-05-29T19:24:41Z

Sorry, no conclusion so far, I still didn't have time to devote to this PR properly.
But I wrote a very pedantic overview of linking libc and dynamic libraries on various targets a couple of years ago, which I need to re-read myself and which had some conclusions, possibly slightly over-engineered.

petrochenkov · 2023-05-30T15:03:34Z

I think we can try flipping the default for NativeLibKind::Unspecified libs only, while still respecting explicit dylib kinds to cover rare cases.

And land this on nightly only to see what breaks on targets that are more similar to Windows than to Linux.

petrochenkov · 2023-05-30T15:04:31Z

And run crater, although I don't expect it showing anything on Linux.
Too bad there's no Windows-based infra for crater.

The previous wording was right in the sense that -Bdynamic with ld-like linkers is only a preference for a dynamic library, not a requirement, so a static library can be linked even despite kind=dylib if there's no dynamic version of it.

That's what I called "too platform specific" above.
That's why I also suggested to document things in terms of the inferred kind and not in terms of actually linked libraries.

Based on my experiments, this isn't actually a preference: the linker will not search for static libraries if -Bdynamic is specified.
