Cross compiling from Linux to Windows with disabled default features for std is giving error about xargo

[RalfJung]

The error is caused here:

xargo/src/sysroot.rs

Line 67 in 23c6fd2

for file in ["rsbegin.o", "rsend.o", "crt2.o", "dllcrt2.o"].iter() {

You need to install the x86_64-pc-windows-gnu target, I think, to get those files? I am not an expert in Windows matters but I assume that xargo code was added for a reason.^^

I can compile just fine using normal cargo.

How are you building the standard library using normal cargo?

I'm not building the standard library using normal cargo and I've x86_64-pc-windows-gnu installed, otherwise I wouldn't be able to compile it using standard cargo.

Then what do you mean by "I can compile just fine using normal cargo"? I thought you meant building the standard library, now I am not sure.

Hm, can you check if the file "crt2.o" exists anywhere in /home/user/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu? It used to be at /home/user/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu/lib/crt2.o but maybe it moved...

Looks like these days the files reside at

~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu/lib/self-contained/crt2.o
~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu/lib/self-contained/dllcrt2.o
~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu/lib/rsbegin.o
~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu/lib/rsend.o

FWIW, the PR that broke this is probably rust-lang/rust#72999.

The pull request works. Thanks for your help.
