Solving anchor problems on Solana

As a developer who builds up and used decentralized applications (DAPPS) on the Solana blockchain, it is not unusual to arise problems with anchor building. In this article we will deal with some frequent problems and offer solutions to fix them.

What are anchor buildings?

Anchor is a popular framework for the construction of Dapps on Solana. It offers a number of tools and libraries that simplify the creation and provision of applications. As with any other framework, anchor builds require configuration and optimization to ensure smooth provision.

frequent problems with anchor buildings

Here are some common problems that you could encounter when creating an anchor application:

1. Unexpected cfg conditional value:anchor-debug

When creating an anchor project, it is important to specify the correct value for the configuration flag CFG. If this is not correct, the build process can fail.

`Rost

#[Program]

// …

#! [CFG (target_arch = “x64”)]

`

In this example, we state that our program should be compiled on 64-bit X64 architectures. However, if you forget to specify the parameter target_arch, your build fails with an unexpected error.

2. Missing dependencies

Anker -Builds require certain dependencies to work properly. If these dependencies are missing or are not properly installed, your project can encounter problems during the compilation and provision.

`Rost

// missing dependence: Solana program.

// add it to your file cargo.toml:

Solana-Program = “1.9.0”

`

Make sure you added the necessary dependency to your file “cargo.toml” before creating your anchor project.

3 .. False Compiler flags

Anker -Builds use certain compiler flags to optimize and compile your code. If these flags are not set correctly, your build can fail or create unexpected errors.

`Rost

// Set the flag: – -Config = debugg

// add it to your file cargo.toml:

Solana-Program = “1.9.0”

Compiler_flags = [“–Config = debug”]]

`

In this example, we set the compiler flags so that the debug configuration is used.

solutions

Here are some solutions for frequently occurring problems with anchor construction:

1. Check your file cargo.toml

• Make sure you added all the necessary dependencies and specified the correct target architecture.

• Make sure that the dependencies with cargo installed are properly installed.

`Toml

Solana-Program = “1.9.0”

`

2. Use the right compiler flags

• Check your compiler flags to ensure that you match the anchor provided by the anchor.

• You can specify user -defined flags in the Build command, e.g. B. Cargo Build --Config = debug.

`Bash

3 .. Check your dependencies

• Make sure that all dependencies with cargo installed are properly installed.

• Check whether missing or outdated dependencies in your project directory `cargo dependency” are executed.

Best Practices

To avoid common problems, follow these best practices when creating anchor projects:

* Check the dependencies : Always check whether all the necessary dependencies are installed and up -to -date.

* Enter the right compiler flags : Use the specified compiler flags to optimize and compile your code.

* Test thoroughly : Test your build process thoroughly before you provide it for production.

If you follow these guidelines and observe problems with the establishment of anchors, you can ensure smooth provision and a successful execution of your DAPPS based on Solana.
