Incremental compilation failed

[waghanza]

Hi,

With rust 1.34.0-nightly (2019-01-29), I have the following message :

error: can't perform LTO when compiling incrementally

error: aborting due to previous error

error: Could not compile `server`.

To learn more, run the command again with --verbose.

on compilation

 RUSTFLAGS="-C target-cpu=native" cargo build --release

I have not knowledge in rust, so I just want to report bug

The source code is https://github.com/the-benchmarker/web-frameworks/tree/master/rust/rocket

Regards,

This is caused by the settings in Cargo.toml in conjunction with rust-lang/cargo#6564 , nothing actually related to Rocket afaik. I will take a closer look later and see what is the best way to get it running again.

It looks like adding incremental = false in Cargo.toml (in the same section as lto = true) would fix the compilation error. The error should also go away on its own once it's reverted and later re-introduced in a non-breaking way.
