Critical problem with anchor to Solana: Unable to rusty
As a developer with Solana Blockchain, you are unlikely to be a stranger to the importance and maintenance of a reliable and efficient system. There was a critical problem in the structure of the Solana anchor program. In this article, we are immersed in the error message, which prevents developers from successful.
The error: The Solana program v2.1.9 package cannot be built
When you run the “Cargo Build” or similar commands to compile a Solana project, you experience a mistake that points to the rust (rustc"). Specifically, the "Solana program" package seems to be incompatible with the current version of the rust translator.
The question arises from the fact that Rust 1.75.0-Dev (currently active version) does not support building packages, such as the "Solana program" using the Rustc translator. Instead, you need to use another version of the Rust Compiler, for example 1.79.0 or newer version.
Why does this matter
It is impossible that the use of packages with Rustc is a known question that has been reported by developers and maintainers. It is essential to keep the rust translator up to date to ensure compatibility with the Solana luggage manager.
Solve the problem
You have some options to solve this error:
- Refresh the rust translator
: Make sure you use the latest version of the Rust Compiler (1.79.0 or above). You can do this by running the Rustup Update and then updating to the desired version.
- Use a load version : Instead of entering a particular rust version, use the Cargo version mechanism to ensure compatibility. You can set thecargo.toml
file to the latest version:
Toml
[package]
NAME = “Solana Program”
Version = “2.1.9”
[addictions]
Tokio = {version = “1.19”, properties = [“complete”]}
`
- Use another translator : In some cases, you may need to use another translator for construction packages such as the “Solana program”. For example, if you use “Cargo Build” with the “release” flag, you can try to make it with Rust 1.78.0.
Conclusion
There was a critical problem in the structure of the Solana’s anchor program, and it is essential to quickly address this issue. By updating the rust translator or using the cargo version, you must be able to solve the error and to successfully develop projects. Remember to keep the devices up to date to ensure compatibility with the latest versions of Solana and its package manager.
