在Linux Mint上安装SDL2和Raylib的步骤

1. 安装系统依赖

首先安装必要的系统库：

# 更新包管理器
sudo apt update

# 安装SDL2开发库
sudo apt install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev

# 安装Raylib开发库
sudo apt install libasound2-dev libx11-dev libxrandr-dev libxi-dev libgl1-mesa-dev libglu1-mesa-dev libxcursor-dev libxinerama-dev

2. 初始化Go模块

从你的错误信息看，你需要在项目目录中初始化Go模块：

# 创建项目目录
mkdir my-game-project
cd my-game-project

# 初始化Go模块
go mod init mygame

# 这将创建go.mod文件

3. 安装Go绑定库

对于Raylib：

# 安装raylib-go
go get github.com/gen2brain/raylib-go/raylib

# 或者使用go install安装示例程序
go install github.com/gen2brain/raylib-go/raylib/examples/core/2d_camera@latest

对于SDL2：

# 安装go-sdl2
go get github.com/veandco/go-sdl2/sdl
go get github.com/veandco/go-sdl2/img
go get github.com/veandco/go-sdl2/mix
go get github.com/veandco/go-sdl2/ttf

4. 验证安装

创建测试文件验证安装是否成功：

Raylib测试 (main.go)：

package main

import rl "github.com/gen2brain/raylib-go/raylib"

func main() {
    rl.InitWindow(800, 450, "Raylib Go Test")
    defer rl.CloseWindow()

    rl.SetTargetFPS(60)

    for !rl.WindowShouldClose() {
        rl.BeginDrawing()
        rl.ClearBackground(rl.RayWhite)
        rl.DrawText("Raylib Go Works!", 190, 200, 20, rl.LightGray)
        rl.EndDrawing()
    }
}

运行测试：

go run main.go

SDL2测试 (sdl_test.go)：

package main

import (
    "fmt"
    "github.com/veandco/go-sdl2/sdl"
)

func main() {
    if err := sdl.Init(sdl.INIT_EVERYTHING); err != nil {
        fmt.Printf("Failed to initialize SDL: %v\n", err)
        return
    }
    defer sdl.Quit()

    window, err := sdl.CreateWindow("SDL2 Test", 
        sdl.WINDOWPOS_UNDEFINED, sdl.WINDOWPOS_UNDEFINED,
        800, 600, sdl.WINDOW_SHOWN)
    if err != nil {
        fmt.Printf("Failed to create window: %v\n", err)
        return
    }
    defer window.Destroy()

    fmt.Println("SDL2 initialized successfully!")
    sdl.Delay(2000)
}

运行测试：

go run sdl_test.go

5. VS Code配置

确保VS Code的Go扩展已安装并正确配置。如果仍有导入错误，尝试：

# 在项目目录中整理依赖
go mod tidy

# 或者清除模块缓存
go clean -modcache

6. 常见问题解决

如果遇到CGO链接问题，设置环境变量：

# 在~/.bashrc或~/.zshrc中添加
export CGO_ENABLED=1
export CC=gcc

# 然后重新加载
source ~/.bashrc

对于权限问题：

# 确保go路径在PATH中
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin

7. 完整安装脚本

创建安装脚本 setup.sh：

#!/bin/bash

echo "Installing system dependencies..."
sudo apt update
sudo apt install -y libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev
sudo apt install -y libasound2-dev libx11-dev libxrandr-dev libxi-dev libgl1-mesa-dev

echo "Setting up Go project..."
mkdir -p ~/go-projects/game-learning
cd ~/go-projects/game-learning
go mod init game-learning

echo "Installing Go libraries..."
go get github.com/gen2brain/raylib-go/raylib
go get github.com/veandco/go-sdl2/sdl

echo "Installation complete!"

给脚本执行权限并运行：

chmod +x setup.sh
./setup.sh

这些步骤应该能解决你在Linux Mint上安装SDL2和Raylib的问题。如果遇到特定错误，请提供具体的错误信息以便进一步诊断。
