golang plugin failed

Preface

With the popularity of golang language, more and more developers are trying to use golang to write plug-ins to extend the functionality of applications. However, in actual development, golang plug-ins may encounter some problems. This article will discuss some common golang plug-in failure problems and give corresponding solutions.

Problem 1: Plug-in compilation failure

When writing golang plug-ins, sometimes you will encounter compilation failures. Generally speaking, there are many reasons for plug-in compilation failure, such as:

1. Lack of necessary dependent libraries
2. Incorrect compilation environment configuration
3. Syntax exists in plug-in code Error

For these problems, we can adopt the following solutions to troubleshoot one by one:

1. Confirm whether the dependent environment meets the requirements

When the golang plug-in is compiled It may depend on some external libraries, and we need to check whether these dependency environments are normal. You can use the command line tool to check whether the relevant dependent libraries are installed. If they are missing, they need to be installed.

2. Check whether the compilation environment configuration is correct

Golang plug-in compilation needs to ensure that the compilation environment configuration is correct. We need to check and ensure that related environment variables such as GOPATH and GOBIN are set correctly.

3. Check whether there are syntax errors in the plug-in code

If there are syntax errors in the plug-in code, compilation will fail. We need to check and fix grammatical errors in the code to ensure that the code conforms to golang grammar specifications.

Problem 2: Plug-in loading failure

Even if the plug-in is compiled successfully, there may be a problem of plug-in loading failure. Generally speaking, the main reasons for plug-in loading failure are as follows:

1. Architecture error during plug-in compilation
2. Plug-in name or path error
3. Plug-in dependent library loading Failure

For these problems, we can take the following solutions to check them one by one:

1. Confirm whether the plug-in architecture is correct

The plug-in needs to be compiled according to Different operating systems and CPU architectures select different compilation parameters to ensure that the compiled plug-in matches the operating system and CPU architecture. If the architecture selected when the plug-in is compiled is incorrect, the plug-in will fail to load.

2. Confirm whether the plug-in name and path are correct

When loading the plug-in, you need to use the correct plug-in name and path. If the plug-in name or path is incorrect, plug-in loading will fail.

3. Confirm whether the plug-in dependent libraries are loaded correctly

The plug-in may depend on some external libraries, and we need to ensure that these external libraries are loaded correctly. You can specify the library directory that the plug-in depends on through golang's LD_LIBRARY_PATH environment variable.

Conclusion

Although you may encounter some problems when writing plug-ins in golang, as long as we adopt the correct troubleshooting methods, we can effectively solve these problems. In addition to the problems listed above, there are also some problems that may affect the performance and stability of the golang plug-in, such as memory leaks and concurrency issues. We need to investigate and repair them in more detail during the actual development process to ensure the performance of the golang plug-in. quality.
