It looks like cargo is passing gcc linker flags, im not 100% sure how to tell it to pass lld ones but i have found rust-lang/rust#40018 which might let you do it. |
|
LLD supports these arguments just fine, although I'm not sure why it's telling you they were unsupported. |
I see. Do you know how I can fix this? |

Hi @philipahlberg there are two workarounds I am aware of:
The second option is much better but requires nightly. |

I try to use zig as the linker of cargo,but I got the same output like you ,I wonder how you solve it? [...]

error: static library 'unwind' not found. search paths:

H:\RustTools\rustup\toolchains\nightly-x86_64-pc-windows-msvc\lib\rustlib\x86_64-unknown-linux-musl\lib\libunwind.a
suggestion: use full paths to static libraries on the command line rather than using -l and -L arguments
[...]if i try to force zig cc to include the rust libunwind.a in rust's self-contained folder,I receive this is my rustflag in my cargo config |
sorry,i solved it , I found the all the duplicate symbol are in the same rlib file ,and i remove them by hand in build script,now it works fine , just a little trouble |
Could we do that? It seems fairly reasonable for The workarounds suggested here work fine, but those are all one-offs, and don't help to fulfill |

Done in 2836cd5. |

Awesome, thank you! |

Since libgcc_s also includes the exception handling functions, I think |
