error: could not compile `proc-macro2` #768

Closed evandrocoan closed 4 years ago

evandrocoan commented 4 years ago

I am not trying to either use or build this. I am trying to run:

  1. https://github.com/ankitects/anki
  2. Which uses python envs
  3. Which uses qt
  4. Which seems to be using cargo
  5. Which seems to be depending on syn
  6. Which is failing to be built.

I am tried to build this with cargo build --verbose but it is not working.

I tried with both version 1.0.8 and 1.0.15 and the error is the same in both:

$ pwd
/c/Users/Professional/.cargo/registry/src/github.com-1ecc6299db9ec823/syn-1.0.8

$ cargo --version
cargo 1.41.0 (626f0f40e 2019-12-03)

$ rustc --version
rustc 1.41.0 (5e1a79984 2020-01-27)

$ link --version

Running $ rustc --edition=2018 ... gives back:

So the *** is not interpreting the slashes on the path. Why it is using link.exe (from cygwin) if it cannot interpret correctly the paths?

How can I make it stop using cygwins link.exe? What it should be using instead of link.exe?

This sounds like a rustc bug if it is passing wrong arguments to the linker, or a linker bug if the linker isn't interpreting its arguments correctly. I don't think there is any change in Syn that would be involved in this.
