Unable to `-Zbuild-std` for `mips-unknown-linux-musl` #1416

Open wcampbell0x2a opened 6 months ago

wcampbell0x2a commented 6 months ago

Checklist

Describe your issue

The following MR adds statically included libc for several architectures. However, mips-unknown-linux-musl fails. https://github.com/wcampbell0x2a/mempeek/actions/runs/7520357008/job/20469941084?pr=2

Since mips-unknown-linux-musl is target tier 3 now, I need to build-std.

Version: cross v0.2.5

Command: cross build --bin mempeek --locked --release --target mips-unknown-linux-musl -Zbuild-std

error: linking with `mips-linux-muslsf-gcc` failed: exit status: 1

Can you try using a new image for mips? Either update cross to the lastest version on main cargo install cross --git https://github.com/cross-rs/cross or set in Cross.toml

[target.mips-unknown-linux-musl]
image = "ghcr.io/cross-rs/mips-unknown-linux-musl:main"

I know though there's still problems with this target, see https://github.com/cross-rs/cross/actions/runs/7471174056/job/20331075105#step:12:1937

wcampbell0x2a commented 6 months ago

I tried both of those solutions, same results of failure.

Emilgardis commented 6 months ago

Same result as in mips-linux-muslsf-gcc: error: crt1.o: No such file or directory or same error as in ci?

Looks like the same as my CI:

@Emilgardis would there be any WA available to get this built for now ?

Emilgardis commented 5 months ago

Im not sure. Im trying to find a way to solve it with https://github.com/cross-rs/cross/issues/1422 and https://github.com/cross-rs/cross/pull/1432

For now I've just disabled it, but I want a real solution. A possibility would be to use a older rustc, just invoke cross like cross +1.65

wcampbell0x2a commented 5 months ago

Would this be something the rust-lang compiler guys would look into? I assume it's lower priority for them.

Emilgardis commented 5 months ago

I dont know yet if this is something we do or rustc does wrongly yet.

wcampbell0x2a commented 5 months ago

I tried yesterday to use https://github.com/richfelker/musl-cross-make and had the same issues with CRT.

Emilgardis commented 5 months ago

Which makes sense, thats what cross uses ;)

Emilgardis commented 5 months ago

Here's where its installed/setup

wcampbell0x2a commented 5 months ago

So with my local musl-cross-make, I can get the linking further by adding the location of the sysroot to -L:

> fd crt
lib/gcc/mips-linux-musl/9.4.0/crtbegin.o
lib/gcc/mips-linux-musl/9.4.0/crtbeginS.o

rustflags = [
    "-C", "target-feature=+crt-static",
    "-L", "musl-cross-make/output/mips-linux-musl/lib",
    "-L", "musl-cross-make/output/lib/gcc/mips-linux-musl/9.4.0/"
]
target = "x86_64-unknown-linux-musl"

[target.mips-unknown-linux-musl]
linker = "musl-cross-make/output/bin/mips-linux-musl-gcc"

I don't know if this is a rustc issue or not? Anyway, the linker now gives:

  = note: musl-cross-make/output/bin/../lib/gcc/mips-linux-musl/9.4.0/../../../../mips-linux-musl/bin/ld: cannot find -lunwind
          collect2: error: ld returned 1 exit status
wcampbell0x2a commented 5 months ago

Maybe this will work? I don't have time to check: https://github.com/rust-lang/wg-cargo-std-aware/issues/81 / https://stackoverflow.com/a/74060091.

wcampbell0x2a commented 5 months ago

I opened https://github.com/rust-lang/rust/issues/120655, just in case this is an rustc bug.

arun11299 commented 5 months ago

Just as an update, I am now able to build it using the nightly, which is 1.77.

What does your buildchain/config/cmd look like?

Ragnt commented 5 months ago

I'm having this same issue, and came to the same conclusion as you thus far. Can't figure out a way around this.

wcampbell0x2a commented 4 months ago

A solution to this is just to create a symbolic link the libgcc.a into libuwind.a:

ln -s musl-cross-make/output/lib/gcc/mips-linux-musl/11.2.0/libgcc.a /musl-cross-make/output/lib/gcc/mips-linux-musl/11.2.0/libunwind.a

A better solution could be found within rustc, but that will take more effort and investigation.

Im not sure. Im trying to find a way to solve it with #1422 and #1432

For now I've just disabled it, but I want a real solution. A possibility would be to use a older rustc, just invoke cross like cross +1.65

I'm trying to build like this:

cross +nightly build --release --target=mipsel-unknown-linux-musl --no-default-features --features="doh" -Zbuild-std="core,std,alloc,proc_macro"

But I get error:

    = note: this error originates in the macro `include` (in Nightly builds, run with -Z macro-backtrace for more info)

I wanted to try your recipe "cross +1.70 build ..." (trying old versions), but it says:

[cross] warning: unable to get metadata for package
[cross] note: Falling back to `cargo` on the host.
error: toolchain '1.70-x86_64-unknown-linux-gnu' is not installed

How does this thing with older versions work?

Emilgardis commented 2 days ago

1.70 is not old enough. Anyway, to use another toolchain you'll need to install it.

rustup install 1.70
