如何解决 github.com/godror/godror 的 go 构建错误？

Question

在 Mac OS 上，我正在尝试构建以下文件以在 Linux 计算机上运行。

package main

import (
    "context"
    "database/sql"
    _ "github.com/godror/godror"
)

func main() {
    dsn := "user/password@host:port/sid"

    // Open a connection to the Oracle database
    db, err := sql.Open("godror", dsn)
    if err != nil {
        panic(err.Error())
    }
    defer db.Close()

    // Test the database connection
    ctx := context.Background()
    err = db.PingContext(ctx)
    if err != nil {
        panic(err.Error())
    }

    query := "SELECT * FROM table"
    rows, err := db.QueryContext(ctx, query)
    if err != nil {
        panic(err.Error())
    }
    defer rows.Close()

    if err := rows.Err(); err != nil {
        panic(err.Error())
    }
}

我使用以下命令来构建：

env GOOS=linux GOARCH=amd64 go build db.go

错误：

我能够针对 Mac OS 进行构建，但针对 Linux 进行构建时遇到问题。你能帮我解决这些错误吗？

此交叉编译错误是由于

github.com/godror/godror

包使用了 CGO 造成的。要编译应用程序，您需要有效的 gcc 安装和 CGO_ENABLED=1，如软件包的 readme 中所述。 您可以尝试使用 docker 编译 linux/amd64。

示例：

DOCKER_DEFAULT_PLATFORM=linux/amd64 docker run --rm -v "$PWD":/app -w /app golang:1.21 go build -v db.go

这将在 Docker 容器中构建应用程序并将可执行文件保存在当前目录中。
