can not build Windows 32-bit executable with Cargo 1.32.0 on Windows 10 x64

[62mkv]

Problem
Trying to build simple Rust (v. 1.32.0) executable for Windows 32 (i686-pc-windows-gnu) and process fails with error: linking with gcc failed: exit code: 1

Steps

1. src/main.rs:

fn main() {
   println!("Hello world");
}

2. .cargo/config:

[build]
target = "i686-pc-windows-gnu"

3. Cargo.toml:

[package]
name = "rust-est"
version = "0.1.0"
edition = "2018"

[dependencies]

4. cargo build --verbose brings this:

>cargo clean

>cargo build --verbose
   Compiling rust-est v0.1.0 (C:\Develop\Rust\rust-est)

error: aborting due to previous error

error: Could not compile 'rust-est'.

Caused by:

Possible Solution(s)

If I comment out the [build]\target line in .cargo/config file, .exe file builds and runs fine. But I need to link it as a Win32-executable, because I need to call Win32-library from it. And if you call it from x64-executable, it throws a %1 is not a Win32 application error. :(

NB: by looking at

  = note: ld: cannot find Files: No such file or directory
          ld: cannot find (x86)\ImageMagick-6.9.8-Q16-HDRI\lib: No such file or directory

it feels as if a path to ImageMagick library folder is incorrectly parsed (or provided) without escaped spaces, but I have no slightest idea as to which tool might be the culprit here :(

It looks like there may be some environment variables in play here or perhaps a shell script along the way injecting arguments, but this unfortunately doesn't look like a cargo/rustc bug

[62mkv]

ok @alexcrichton I understand it perfectly fine but how (as a cargo user) do I go about resolving it ? I can provide any information that's missing, so that we could decide which part of the toolset (if any) should this be raised for

[62mkv]

first question - is this (i686-pc-windows-gnu) even legit toolchain to build Win32-application

[alexcrichton]

Unfortunately this isn't the best venue to debug toolchain issues, but perhaps users.rust-lang.org can help?

[62mkv]

Well, the idea was that here I could find people who at least understand how it works and provide some guidance as to how to localize the root cause. Another point of posting it here is that people with similar problem might later find it here as well. But I understand your point. Will ask on the forum.

It seems I have it resolved:

1. installed toolchain "stable-i686-pc-windows-msvc" (mentioned here as the toolchain for 32-bit Windows apps with MSVC)
2. changed target in .cargo/config to target = "i686-pc-windows-msvc"
3. added +stable-i686-pc-windows-msvc into cargo run command (I compile and run from IntelliJ)

So, thanks for suggestions, I think we may close this one!
