Using mrustc 0.9 to bootstrap rust 1.29.0 directly

[daym]

Hi,

so we are progressing nicely to update Rust bootstrapping packages in Guix.

Right now, I'm trying to switch from mrustc 0.9 bootstrapping rust 1.19.0 to mrustc 0.9 bootstrapping rust 1.29.0 directly.

With that, I get the following error messages when building rust 1.29.0's cargo (rust 1.29.0's rustc builds fine) [for comparison: using the same method, rust 1.19.0's rustc and cargo build fine]:

Have you seen that before?

[bjorn3]

What is the output of the following command:

$ ar t /tmp/guix-build-rust-1.29.0.drv-0/output-1.29.0/cargo-build/build_libgit2-sys/lib/libgit2.a

I once got a similar error with my rustc backend when that ar file was corrupted, so that only one object file was readable.

[bjorn3]

That doesn't seem to be the problem.

[thepowersgang]

Might be related to #138 - there's some funnies with library link order.

[daym]

Hmm, how could dtolnay see the linker command that is executed?

[thepowersgang]

The linker command comes from the gcc invocation, that should be in output-1.29.0/cargo-build/cargo_dbg.txt

[daym]

The linker command that fails is:

Moving "-l" "ssh2" to immediately after "-l" "git2" manually makes it work just fine.

This seems familiar; I encountered a similar issue here; my assumption, as noted in that comment, is this is due to a change in linker behavior:

It seems newer toolchains no longer resolve symbols when the library precedes the referencing object file. This has always been the case for static libraries, as far as I'm aware, but now seems to also be the case for shared libs.
