04 Feb Solana: Linker error when trying to run load test for CLI in agave repository
Solana: Connection error when running Cargo CLI test against Agave repository
The error message you see indicates a linker issue in the Solana project. Specifically, it warns against using the bind_at_load function, which has been deprecated in macOS 10.15.
To fix this issue, we need to update the linker flags and configuration in the Cargo test environment. Here is an article that will walk you through these 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
Step 1: Update linker flags and configuration
In the Cargo.toml file, update the following sections:
[link]
ldflags = ["--no-add-linker-flag"]
This flag tells Cargo not to bind the bind_at_loadflag.
Alternatively, you can also add the following command to yourCargo.tomlfile:
[build system]
env = "path/to/macOS"
Replace /path/to/macoswith the actual path to your macOS system (e.g./Library/Developer/CommandLineTools).
Step 2: Run Cargo CLI test
Try running the following command:
load test --bin agave --link-flags=-bind_at_load
This should resolve any linker errors you encounter.
If you encounter any issues or errors, please provide more information about your environment and Solana version. I will be happy to help you further.
Additional tips
- Make sure your computer is running macOS 10.15 or later.
- If you are running the Cargo CLI test in a Docker container, make sure the bind_at_load` flag is not bound due to the Docker build process.
- Please note that updating linker flags and configurations may affect other dependencies or libraries in your project.
I hope this helps to solve the problem! Let me know if you have more questions.
