Can this script provide non-unwind libstd?

Question

Can this script provide non-unwind libstd?

vi opened this issue 8 years ago · comments

As far as I know, removing unwinding (including from stdlib) and not use jemalloc is a way to make Rust static binaries small.

Can rust-cross-libs be used to build libstd like i686-unknown-linux-musl, but without unwinding (i.e. for -C panic=abort)? If yes, what cfg json there shall be?

I tried some weeks ago and it did not work. Tried today and it breaks with:

rustc: /buildslave/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/llvm/lib/IR/Instructions.cpp:1436: void llvm::StoreInst::AssertOK(): Assertion `getOperand(0)->getType() == cast<PointerType>(getOperand(1)->getType())->getElementType() && "Ptr must be a pointer to Val type!"' failed.

I will try again...

Note that this script build shared binaries for the musl target.

Can it also work for static?

Can rust-cross-libs turn into a sort of rustup.rs addon that automatically builds targets if they are not avaliable for usual download? I.e. you specify settings (allocator, unwinding, cpu features, platform, object format, static or not) and it either downloads such things (if it happens to be provided officially) or builds it.

Probably, yes. You need to remove the patch for libc (which forces libc to link dynamically) and adjust the JSON file so the necessary libraries and object files are found by Rust.

I haven't looked at rustup.rs yet, so I cannot say.

I was able to build a cargo-based libstd with the abort panic-strategy for the ARMv5TE targets today 😄.

You're welcome to try the latest rust-cross-libs build script!

How does this project compare or relate to xargo?

Jörg Krause · Answer 7 · Wed Jan 11 2017 15:47:55 GMT+0800 (China Standard Time)

Both do pretty much the same nowadays, I guess. However, I was not able to get xargo to work for me.

Probably, yes. You need to remove the patch for libc (which forces libc to link dynamically) and adjust the JSON file so the necessary libraries and object files are found by Rust.

Could you please specify how can I exactly specify rust to search libc.a in a specific folder.
I can't find a way in the parameters list.

That's what I've got when trying to build the statically linked musl rust toolchain.

error: could not find native static library `c`, perhaps an -L flag is missing?
