Keep getting linker errors

help
1

I used rust fine for the first week or so, but when I got to the socket part of the second edition book, I started getting linker errors. (error: linking with link.exe failed: exit code: 1120).

I have no stray link.exe in my path since calling link.exe from the command line doesn't run anything.
It seems to be calling MSVC, which is weird considering I've read that rust comes bundled with the required MinGW stuff.

I'm on the latest nightly and each time I do cargo build I get this output:

error: linking with link.exe failed: exit code: 1120

Are you using incremental compilation (i.e. set CARGO_INCREMENTAL=1) on nightly?

At work I was using nightly for a while to take advantage of incremental compilation (a full compile is usually 10+ minutes) but found that sometimes incremental compilation will result in incorrect symbols and a bunch of "unresolved external symbol" errors. A cargo clean whenever it happened was usually enough to fix the issue, but that defeated the entire reason I was using nightly.

Thanks!

I still got this problem in 2019-09-20!!

It occurs in cross compile from macOS to Windows with x86_64-pc-windows-gnu.

I cross compile for Linux with CARGO_INCREMENTAL=1 it's OK. But for Windows, I need to set it to 0.

You've got to love stumbling on old threads which solve your exact problem! :stuck_out_tongue_winking_eye:

If you've got time, you may want to make an issue in the Rust repo for this. I'm not able to reproduce it any more (Linux is my main OS), but the compiler team will probably want to figure out why linking isn't working properly.
