Looks like the PATH / LD_LIBRARY_PATH issue is back, that used to happen here: #402
If you run clippy with the latest rustup, you get this:
C:/Users/Christopher/.cargo/bin/cargo-clippy.exe: error while loading shared libraries: rustc_driver-36e125fb8252217f.dll: cannot open shared object file: No such file or directory
rustc 1.15.0-nightly (8f02c429a 2016-12-15)
rustup 1.0.0 (17b6d21 2016-12-15)
Could be caused by the .multirust -> .rustup change. If you put the full sysroot/bin path into your PATH, everything seems to work.
Clippy issue is over here: Manishearth/rust-clippy#1395
This is rust-lang/cargo#3394
For anyone like me who is wondering which path is missing from PATH:
Thats for my windows toolchain but the idea should be similar for any other windows toolchains or affected platforms.
