Isn't this exactly the same as issue #6731, which you filed, and which was closed as working as intended? |
Short description: As issue #6731, Package and import the package is mixed, ie, the golang program direct call cgo! As this issue, Package and import the package separatel, this package uses cgo way! Describe the problem differences: As issue #6731, 'test.go' is the main entrance of the program, not a golang package; I am currently on golang learning to know is that a program with a main entrance, Compile with program names, such as 'go build test.go' should be passed, but the windows platform is not compiled; while the Linux platform is good! (Package and import the package separatel, this package uses cgo way!) As this issue, build package is ok; but import this package, links can not pass! (Package and import the package separatel, this package uses cgo way ) |
This issue appears identical to 6731. In both issues you are using go build incorrectly. There may be a separate issue for the go tool producing a binary even when compilation is aborted. If this is the case please open a new issue stating this clearly. Status changed to WorkingAsIntended. |
