So I was trying to migrate the ctest crate [0] from appveyor to travis and the following targets pretty much worked out-of-the-box:
x86_64-pc-windows-gnux86_64-pc-windows-msvci686-pc-windows-msvc
but I am running into linker errors with the i686-pc-windows-gnu target. My .travis.yml (ctest windows branch) file is pretty much just (you can check out the branch for all the details):
- name: "x86_64-pc-windows-gnu"
env: TARGET=x86_64-pc-windows-gnu
os: windows
- name: "i686-pc-windows-gnu"
# Try hard to get the right gcc / ld versions used:
env: TARGET=i686-pc-windows-gnu PATH=$PATH:/c/Program\ Files\ (x86)/Rust/bin:/c/msys64/mingw32/bin
os: windows
- name: "x86_64-pc-windows-msvc"
env: TARGET=x86_64-pc-windows-msvc
install: true
os: windows
- name: "i686-pc-windows-msvc"
env: TARGET=i686-pc-windows-msvc
os: windows
install: rustup target add ${TARGET}
script: cargo test --all --target=${TARGET}
produces this error:
error: linking with `gcc` failed: exit code: 1

I’d guess that’s because an incorrect mingw version is being picked up (I tried jugling with PATH without much luck). Am I doing something wrong? (is this working as intended?) Is there a better way to configure which mingw version is used?
[0] the ctest crate is used to verify the ABI of Rust C FFI library wrappers like the libc wrapper which is used by the std library.
