Error: Unable to create a solana program due to the requirement of rust compiler version
As a developer working with Solana Blockchain, you may face a mistake trying to create your own Solana program. Special error message “Error: Package” Solana Program v1.18.26cannot be built because it requires RustC 1.75.0 or younger "is quite informative but also frustrating.
In this article, we will look at what causes the problem and give action to solve it.
Question
The error message indicates that “Solana-program v1.18.26 package is not compatible with the rust compiler version 1.75.0 or younger. To create your own programs, Solana requires at least a rust version of 1.73.0 (especially RustC 1.74.0).
Why does it matter?
The Solana program requires rust because it is designed using rust compiler program for the program and tying. However, if you are trying to use a package that depends on another package that only works with the parent rust version, you will face this error.
Solution of the question
To resolve this issue, follow these steps:
- Update your rust compiler
: Make sure you have the latest rust installed. You can check the current version by launching the RustC -Reverersion terminal. If it is an older version (for example, 1.74.0), update to a newer version (for example, 1.75.0).
- Check Addictions : Check that all packages of your Solana program are compatible with the updated rust compiler. You can use tools such as checking the “Rustup tool” or “freight check” to identify all incompatible addictions.

Update Solana-Program Pack
: If you use a package such as Solana Program v1.18.26, update it to the latest version that supports the minimum required rust compiler version (for example,` Solanaprogram Solana Program v1.20.0 ‘ ).
- Try to build again : After updating your addiction and solving any incompatibility problems, try to restore the program using cargo or RustC.
Additional tips
- Make sure your system has a compatible rust environment installed.
- If you are working on a large project, consider improving all packages on their latest versions at the same time. This can help reduce the number of compatibility problems and facilitate solving them later.
- Always check each package documentation you use in your projects to make sure they are compatible with the latest rust version.
When performing these steps and tips, you should be able to solve the error and successfully create your own Solana programs using the desired rust compiler version.
