analyze
In the project, I used Alibaba Cloud's storage and Amazon's storage, which are divided into domestic and foreign versions. The docking SDK is the Go version SDK, so I packaged Alibaba Cloud's Go SDK into a c static library, and packaged the AWS SDK Create a static library, and then call these two static libraries in the business program, and then report the error as above.
Guess, it is because the SDK of Alibaba Cloud and the SDK of AWS use the same underlying content in go, and after loading two static libraries, a duplicate definition error is caused.
Solution
Based on the above guesses, the Go SDK of Alibaba Cloud and the Go SDK of AWS are packaged in a unified way, and it is a static library everywhere outside, so that there will be no problem of multiple definitions.
After testing, the problem is solved.
