I get the error "linking with cc failed"

[cryp2one]

warning: function is never used: sma_helper

error: linking with cc failed: exit status: 1

[gregyjames]

That's a function I defined for later Bollinger Band calculations. You could try deleting the sma_helper function from lib.rs before running cargo build

[Franky1]

No i don't think that is the reason.
The build failed with a linker error.

@cryp2one

• which platform are you using?
• are there more messages above the warning?

@Franky1 I'm getting the same error:
