link_dead_code flag breaks sodiumoxide build

0067223
Opened by Andrey Snow at 2021-10-06 03:45:54

When trying to disable dead code elimination project fails to build.

To be clear, this works: cargo test --no-run this doesn't: RUSTFLAGS=-Clink_dead_code cargo test --no-run

Build log:

error: linking with `cc` failed: exit code: 1

  4. @andoriyu & @sreekanthn, can you tell us why you are compiling with -Clink-dead-code? That would help us in determining the priority of investigating this issue.

  5. Hi Micheal

    For me, the error appears when I tried to build the SDK of the project : https://github.com/hyperledger/indy-sdk

    So I am unable to answer why this flag has been turned on by the build script in this SDK

    thanks Sreekanth

  6. In my car it's just to get better test coverage information.

  7. Thanks for the feedback. We'll discuss it in the next @rust-lang/compiler meeting.

    Michael Woerister at 2017-11-14 09:21:15

  8. @sreekanthn I've got the same problem. Any luck solving it so far?

    Southern-j at 2017-11-16 08:00:43

  9. Can one of you two try to go back in time and see if your project works with an older release? It'd be good to try and get an idea if this is a long-standing bug or a recent regression. Also, any attempt to minimize the test case that is broken would be most welcome. =)

  11. Hi Jonathan

    Sorry, I did not check for a few days. If your intention is to run the Hyperledger Indy demo code and try your clients (which is what I was trying to do), you can follow this link to setup a working environment. I have not tried to recompile the source beyond this.

  12. Hi Sreekanth,

    For indy project you need to downgrade libsodium version from 1.0.15 to 1.0.14

    JFYI brew rm libsodium brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/cc97dea94e2b9daf01823df81b171e1bcdc4b272/Formula/libsodium.rb brew info libsodium

  13. Is https://github.com/alexcrichton/futures-timer/issues/2 the same issue? I get this triggered when running https://github.com/xd009642/tarpaulin on my project, which uses futures-timer.

    The futures-timer#2 issue shows a pretty minimal example of this happening. (compile with RUSTFLAGS="-C link-dead-code")

    tarpaulin indeed uses this flag for better coverage analysis.

    Ruben De Smet at 2018-02-26 08:40:21

  14. I've found another instance if this happening: https://dev.azure.com/andoriyu/libpandemonium/_build/results?buildId=32

    Only affects stable, but works on Beta and nightly. However, for some reason, it works just fine on stable under FreeBSD. Insert visible confusion here.
