我是 go lang 開發的初學者，我嘗試從 go 服務器連接云 oracle 數據庫（使用 'github.com/godror/godror' 包）。我安裝了 Oracle 即時客戶端并設置了環境路徑。Go 服務器正在運行并且能夠建立連接和查詢。但是當我構建一個生產應用程序時出現了這些錯誤。命令：env GOOS=linux GOARCH=amd64 go build -o odb db_main.go../github.com/godror/godror/orahlp.go:452:53: undefined: VersionInfo../github.com/godror/godror/orahlp.go:461:53: undefined: VersionInfo../github.com/godror/godror/orahlp.go:479:19: undefined: VersionInfo../github.com/godror/godror/orahlp.go:480:19: undefined: VersionInfo../github.com/godror/godror/orahlp.go:481:30: undefined: ObjectType../github.com/godror/godror/orahlp.go:482:31: undefined: Event../github.com/godror/godror/orahlp.go:482:42: undefined: SubscriptionOption../github.com/godror/godror/orahlp.go:482:64: undefined: Subscription../github.com/godror/godror/orahlp.go:483:10: undefined: StartupMode../github.com/godror/godror/orahlp.go:484:11: undefined: ShutdownMode../github.com/godror/godror/orahlp.go:484:11: too many errors```My server code(db_main.go)```package mainimport ( "database/sql" "encoding/json" "fmt" "log" "net/http" "time"_ "github.com/godror/godror")// VersionInfo,ObjectType,Event,SubscriptionOption,Subscription,StartupMode,ShutdownModevar db *sql.DBfunc main() { var err error db, err = sql.Open("godror", "xyz/[email protected]:1521/sampledb") if err != nil { log.Println("Error") fmt.Println(err) return } defer db.Close() port := ":8000" http.HandleFunc("/insert", InsertData) http.HandleFunc("/list", GetList) log.Println("Tranzo-Shahi Oracle DB running in ", port) httpErr := http.ListenAndServe(port, nil) if httpErr != nil { log.Println("Tranzo-Shahi Oracle DB Error: ", httpErr.Error()) }}

不幸的是，原始問題沒有提到構建運行的位置。知道這一點很重要。
當您嘗試交叉編譯代碼時，godror文檔指出了可能出現的問題。在他們的文檔中：Cgo is required, so cross-compilation is hard, and you cannot set CGO_ENABLED=0!
我建議在 Linux 機器上運行你的構建。（驗證它是否安裝了gcc。）
運行您的構建env CGO_ENABLED=1 go build -o odb

運行env GOOS=linux GOARCH=amd64 go build -o odb并且不指定任何文件。如果您確實指定了一個，db_main.go那么您需要指定必須包含在構建中的包中的所有文件。
