This is a dup of

#32859

[Kimundi]

Actually, looking at #32859 in more detail this might be a different issue?

[alexcrichton]

Looks like the wrong linker is being used? The compiler is using "gcc"

[nagisa]

~/.cargo/bin/rustup run nightly cargo rustc --release --target=x86_64-pc-windows-gnu -- -C linker=x86_64-w64-mingw32-gcc works, so we are invoking the wrong linker indeed.

[alexcrichton]

Closing as I believe this was just the wrong linker being used.

[alexxroche]

I tried cross compile today with rustc 1.33.0 (2aa4c46cf 2019-02-28) and cargo 1.33.0 (f099fe94b 2019-02-12) on debian 9. After rustup target add x86_64-pc-windows-gnu ; sudo apt-get install -y mingw-w64 the error that I got lead me straight here. Jorge Aparicio's rust-cross and Screwtape had the clue that solved it for me:

cat >>~/.cargo/config <<EOF
[target.x86_64-pc-windows-gnu]
linker = "/usr/bin/x86_64-w64-mingw32-gcc"
EOF

Then cargo build --release --target=x86_64-pc-windows-gnu worked. (cargo rustc --release --target=x86_64-pc-windows-gnu -- -C linker=x86_64-w64-mingw32-gcc also worked, but that doesn't seem like the more intuitive of the two options.)
[Sorry to necro this issue, but it doesn't feel closed. Maybe rustup target add ... should append to ~/.cargo/config ?]

[thmo]

Should this work out of the box? It does not for me, I had to change ~/.cargo/config as described in the previous comment.

Therefore I think the issue should be reopened.

[elichai]

Agree. shouldn't rustc or whatever be able to find the correct linker itself?

[nagisa]

rustc has the logic for finding a correct host toolchain, however the cross-toolchains can be present in varying forms, shapes and locations, making finding them automagically not very feasible.

[thmo]

But wouldn't it already help to default the linker to at least a possible toolchain-specific linker (say x86_64-w64-mingw32-gcc in that case) instead of gcc, as the latter will be wrong for most if not all cross toolchains?
