Thanks to MSYS2 guys' work, I have successfully built LLVM package with Polly, Clang, compiler-rt, and libunwind packages version 20.1.2. I still trying built libc++ and libc++abi, but it is not going smoothly. Is there any other blocker to build Rust for cygwin? -- Takashi Yano <takashi.y...@nifty.ne.jp> -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
