Q: How to report build issues? #56

Closed dvdplm closed 4 years ago

dvdplm commented 4 years ago

This is a meta issue. I have a rust project that fails to build when using zld but builds fine otherwise. Should I just open an issue with the info I have (almost none, other than the rustc error) or do you have a set of troubleshooting steps I can follow to provide more useful issue reports?

Thanks! :)

michaeleisel commented 4 years ago

the best thing would be a way for me to reproduce it, along with the rustc error you're seeing

bjorn3 commented 4 years ago

Rustc will write the compiled object files to the output directory (usually target/debug/deps or target/release/deps). If there was a linker error then the object files are not removed afterwards. You can force it to never remove the object files using -Csave-temps.

Does running the linker invocation shown in the error message give a more descriptive error message? It is possible that rustc accidentally swallows part of the error message shown by the linker. Also does it say that the linker exited with a signal or with a non-zero exit code?

This is the repository where i encountered the error: substrate-telemetry. My RUSTFLAGS were set to: -C target-cpu=native -C lto=off -C link-arg=-fuse-ld=/usr/local/bin/zld.

This is the full error:

telemetry enables LTO.

telemetry enables LTO.

Aha, indeed. Thank you so much. 👍

Closing as invalid.

michaeleisel commented 4 years ago

is this really invalid? there's still a difference in behavior between ld and zld, no?

dvdplm commented 4 years ago

I believe it is. Here's what I did: With RUSTFLAGS set to -C target-cpu=native -C lto=off -C link-arg=-fuse-ld=/usr/local/bin/zld the build fails, and I erroneously assumed zld was the problem; to verify I unset RUSTFLAGS and recompiled (which works). The real culprit is the lto setting.

Sorry for the noise!

michaeleisel commented 4 years ago

no worries
