Solana: Linker error when trying to run cargo test for the CLI in agave repository

The error message you are encountering indicates a linker problem with the Solana project. In particular, it warns against the use of bind_at_load, which has been deprecated since macOS 10.15.

To fix this, we will need to update the flags and linker configuration in your environment. Load testing. Here’s an article that walks you through the steps:

Prerequisites

  • Install the latest version of Solana CLI (0.51.x or later) by running cargo install solana-cli

  • Clone the Agave repository: git clone

1. step: update flags and linker configuration

In your Cargo.toml file, update the following sections:

[link]
ldflags = ["--no-add-linker-flag"]

This flag tells Cargo not to link the bind_at_loadindicator.

Alternatively, you can add the following command to your file. "Cargo.toml":

[build system]
env = "path/to/macOS"

Replace /path/to/macos with the actual path to macOS on your system. (for example, /Library/Developer/CommandLineTools).

Step 2: Run Cargo test for CLI

Try running the following command:

cargo test --bin agave --link-flags=-bind_at_load

This should resolve any linker errors you are experiencing.

If you encounter any problems or errors, please provide more information about your environment. and version of Solana. I will be happy to help you further.

Additional Tips

  • Make sure you have macOS 10.15 or later installed on your system.

  • If you are running the Cargo test for the CLI in a Docker container, make sure the bind_at_load flag is not bound due to the Docker build process.

  • Note that updating flags and linker configuration may affect other dependencies or libraries in your project.

I hope this helps to solve the problem! Let me know if you have any more questions.
