When I run one of the test file in Ethereum on mac (10.13.4)
I came across this mistakes

ld: 33 duplicate symbols for architecture x86_64
clang-4.0: error: linker command failed with exit code 1 (use -v to see invocation)

Compilation finished with exit code 2

Can anyone tell me what happened to my link and how should I do?

[ianlancetaylor]

Those look like C symbols, not Go symbols. My first guess would be that some cgo comments need to declare functions as static. Or perhaps a #cgo LDFLAGS line is causing the same code to be linked in twice. Or there are various other possibilities. You didn't say what exactly you were building (there is a lot of Ethereum code) so I don't know where the problem is.

We don't normally use the issue tracker for questions about how to build or write things in Go. Please see https://golang.org/wiki/Questions . Thanks.

I don't think there is anything to fix in the Go project here, so closing this issue. Please comment if you disagree.

Thank you for your suggestion !
I will close this issue and move to golang wiki

@dylanpoe have you solved this issue?

@weijinxy This issue is closed, so this is not a good place to look for an answer. And, as noted above, please see https://golang.org/wiki/Questions. Thanks.

[lucas7788]

@dylanpoe how you solved the issue?

[Timmy-Cai]

just add CGO_ENABLED=0, and it works, if build or run with goland, you need set it on goland setting
