Failure to compile frame with nightly compiler

[ocrickard]

Hello! Exciting framework, I'm trying to do some performance work on Paillier encryption, but I can't seem to compile this framework with the nightly Rust compiler. I followed the steps in the readme, and attempted to compile the framework using cargo build.

I see that there was one prior issue that was opened and closed related to frame build support (#26 I believe), however I am uncertain if this is the same underlying issue.

Here's my setup:

Default host: x86_64-apple-darwin

installed toolchains
--------------------

stable-x86_64-apple-darwin
nightly-x86_64-apple-darwin (default)

active toolchain
----------------

nightly-x86_64-apple-darwin (default)
rustc 1.35.0-nightly (8159f389f 2019-04-06)

And here's the output of the build command:

$ cargo build
warning: An explicit [[bench]] section is specified in Cargo.toml which currently
disables Cargo from automatically inferring other benchmark targets.
This inference behavior will change in the Rust 2018 edition and the following
files will be included as a benchmark target:

* /Users/ocrickard/src/rust-paillier/benches/helpers.rs
* /Users/ocrickard/src/rust-paillier/benches/macros.rs

This is likely to break cargo build or cargo test as these files may not be
ready to be compiled as a benchmark target today. You can future-proof yourself
and disable this warning by adding `autobenches = false` to your [package]
section. You may also move the files to a location where Cargo would not
automatically infer them to be a target, such as in subfolders.

Hi @eNipu !
I am using nightly-x86_64-apple-darwin unchanged - rustc 1.44.0-nightly (94d346360 2020-04-09) and cargo build works fine. Can you help me to reproduce please ?

Hi @omershlo
Please check my settings and cargo build log

This is my setting:

error: could not compile `framp`

@omershlo I also tried with stable version in Ubuntu 18.04. But similar error log is given.
I guess the framp compilation is causing the problem.

[omershlo]

what OS are you using ?

[eNipu]

Distributor ID: Ubuntu
Description:    Ubuntu 18.04.5 LTS
Release:        18.04
Codename:       bionic

[omershlo]

I am using MacOS.
Can you try running on Mac ?

[eNipu]

@omershlo ,
Here are the build error logs for MacOS.

warning: An explicit [[bench]] section is specified in Cargo.toml which currently
disables Cargo from automatically inferring other benchmark targets.
This inference behavior will change in the Rust 2018 edition and the following
files will be included as a benchmark target:

* /Users/al-amin/Development/Playground/Rust/rust-paillier/benches/helpers.rs
* /Users/al-amin/Development/Playground/Rust/rust-paillier/benches/macros.rs

This is likely to break cargo build or cargo test as these files may not be
ready to be compiled as a benchmark target today. You can future-proof yourself
and disable this warning by adding `autobenches = false` to your [package]
section. You may also move the files to a location where Cargo would not
automatically infer them to be a target, such as in subfolders.
