func GetClangVersion

func GetClangVersion() (string, error)

GetClangVersion returns the version string of clang as semver-formant This string format can be compared by semver buitin package. ref: // https://pkg.go.dev/golang.org/x/mod/semver#Major clang may not work well because version output results may differ depending on the platform.
