Compile problem with Solana anchor
The Solana anchor build process encountered an error that prevented the installation of the latest version of the Solana program package. The error message indicates a compatibility issue with the Rust language used to build and compile Solana.
Error message:
error: solana-program v2.1.10 cannot be built because
it requires rustc 1.79.0 or later, and the target is stable-nightly-2023
Explanation of the problem:
The error message indicates that the Solana program package (“solana-program”) requires Rust 1.79.0 or later to build, but the target configuration used to build the anchor uses an older version of Rust (1.78.x).
To fix this issue, we need to update the Rust version used in the anchor build process to match the required version (1.79.x). Here is a step-by-step guide to fix the issue:
Step 1: Update Rust Version
Update the Rust version used in the Solana package to 1.79.x:
,,beating
rustup update –default stable-nightly
This command updates the default Rust version to the latest stable Nightly version.
Step 2: Rebuild the Solana package
Rebuild the Solana package using the updated version of Rust:
,,beat
payload build --target wasm32-unknown-unknown --release
This command builds the Solana package using the updated version of Rust and targets the wasm32-unknown-unknown configuration that is compatible with the anchor build process.
Step 3: Run the anchor build
Run the anchor build command again to install the rebuilt Solana package:
,,beat
anchor build –target wasm32-unknown-unknown
This command builds the Solana package using the updated version of Rust and targets the wasm32-unknown-unknown configuration that is compatible with the anchor build process.
After the anchor build has been run:
After the anchor build has completed successfully, you should be able to run the Solana package without encountering any issues:
,,beating
freight run – no run
This command runs the Solana package using Rust and should work as expected.
Troubleshooting tips:
- Make sure the Rust version used to build the anchor is updated to 1.79.x or later.
- Before rebuilding, check that the Solana package does not report any dependencies or errors.
- If the problem persists after updating Rust and rebuilding the Solana package, try clearing the cache and rebuilding from the anchor command line:
anchor build --clear-cache
Conclusion:
The Solana anchor build process encountered an error that required you to update the Rust version used in the Solana package to version 1.79.x or later. By following the steps outlined above, you should be able to resolve the issue and successfully install the rebuilt Solana package.
