rust is broken

[crab2313]

rustc is broken and can't compile an empty program like this:

fn main() {}

$ rustc a.rs
error: linking with `gcc` failed: exit code: 1

Having the same issue when trying to build packages for this project -> https://github.com/jwilm/racerd with the additional linker error:

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.2.0/../../../../x86_64-w64-mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-gccmain.o):gccmain.c:(.data+0x0): undefined reference to __CTOR_END__

Found a relevant issue in the rust repo -> rust-lang/rust#48272

Also, it would be nice to have a newer version of rustc, 1.15 is relatively old now.

Rust 1.29.2 in repo now

@Zapeth @Alexpux @crab2313 did you find a solution for this issue?

I'm running the following and still getting this error - rustc 1.35.0 (3c235d560 2019-05-20)

>cargo build --target x86_64-pc-windows-gnu

@gkorland it's rust-lang/rust#47048 and it applies only to Rust installed using official packages so you are asking in wrong repo.

You will have to find crt2.o, dllcrt2.o, libmingwex.a and libmsvcrt.a from your MinGW toolchain and copy those libs to ~/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu/lib every time you update Rust.

@mati865 thanks!
