Cmake：Win10 如何编译 midifile C++应用程序

先从 Microsoft C++ Build Tools - Visual Studio

下载 1.73GB 安装 "Microsoft C++ Build Tools“

下载：midifile 项目 , 将 midifile-master.zip 解压到 D:\Music-soft

CMake是一个跨平台的自动化建构系统,它使用一个名为 CMakeLists.txt 的文件来描述构建过程。CMake可以运行在Windows和Linux环境下，根据配置的编译器不同，生成符合所在操作系统的 Makefile 文件，在Windows下可以生成VS的工程文件系统。
将 CMake/bin 目录加入到系统环境变量Path 中

这是一个将开放式基金数据转换为 MIDI音乐的 C++ 程序示例。该程序将基金净值映射为 MIDI音符的音高

/funds/data/660008.csv 文件开头：
date,jz,ljjz
2016-01-04,1.1141,1.1141
2016-01-05,1.1161,1.1161

2.编写 tools/fund2mid.cpp 程序，如下

#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <cstring>
#include <algorithm>
#include <sstream>
#include "MidiFile.h"

using namespace std;
using namespace smf;

// CSV 数据结构/
struct FundData {
    string date;
    double jz;
};

// 解析 CSV 文件（适配三列格式）
vector<FundData> readCSV(const string& filename) {
    vector<FundData> data;
    ifstream file(filename);
    string line;
    
    // 跳过标题行
    getline(file, line);
    
    while (getline(file, line)) {
        // 使用字符串流分割三列
        stringstream ss(line);
        string date, jzStr, ljjzStr;
        
        // 按逗号分割字段
        getline(ss, date, ',');
        getline(ss, jzStr, ',');
        getline(ss, ljjzStr); // 第三列不需要使用
        
        if (date > "2024-01-01") {
            try {
                double jz = stod(jzStr);
                data.push_back({date, jz});
            } catch (const exception& e) {
                cerr << "解析错误: " << line << endl;
            }
        }
    }
    return data;
}

// 生成 MIDI 文件
void generateMIDI(const vector<double>& prices, const string& fcode) {
    MidiFile midiFile;
    midiFile.addTrack();
    midiFile.setTicksPerQuarterNote(480);// PPQ 需与 addNoteOff 参数一致
    
    // 计算价格范围
    auto [minIt, maxIt] = minmax_element(prices.begin(), prices.end());
    double minPrice = *minIt;
    double maxPrice = *maxIt;
    double priceRange = maxPrice - minPrice;
    
    // 音符范围配置
    int minNote = 48; // C3
    int maxNote = 84; // C5
    if (maxPrice / minPrice < 84.0/48.0) {
        maxNote = static_cast<int>(50 * (maxPrice / minPrice));
    }
    if (maxNote % 2 != 0) maxNote++;
    
    // 添加音符事件
    int track = 0;
    int channel = 0;
    int velocity = 80;
    int timeCounter = 0;
    int PPQ = 480; // 音符持续时间为 1个四分音符（480 ticks）
    
    for (double price : prices) {
        int pitch = (priceRange < 0.001) 
            ? (maxNote + minNote) / 2 
            : minNote + static_cast<int>((price - minPrice) / priceRange * (maxNote - minNote));
        
        midiFile.addNoteOn(track, timeCounter, channel, pitch, velocity);
        midiFile.addNoteOff(track, timeCounter + PPQ, channel, pitch);
        timeCounter += PPQ; // ms 间隔1拍, 单位：毫秒 
    }
    
    // 保存文件
    string outputFile = "melo_" + fcode + ".mid";
    midiFile.write(outputFile);
    cout << "生成成功: " << outputFile << endl;
}

int main(int argc, char** argv) {
    if (argc != 2 || strlen(argv[1]) != 6) {
        cerr << "用法: " << argv[0] << " <6位基金代码>" << endl;
        return 1;
    }
    
    string fcode = argv[1];
    string csvFile = "/funds/data/" + fcode + ".csv";
    
    try {
        auto data = readCSV(csvFile);
        if (data.size() < 20) {
            cerr << "数据不足: " << data.size() << " < 20" << endl;
            return 2;
        }
        
        vector<double> prices;
        for (auto& entry : data) {
            prices.push_back(entry.jz);
        }
        
        generateMIDI(prices, fcode);
    } catch (const exception& e) {
        cerr << "错误: " << e.what() << endl;
        return 3;
    }
    
    return 0;
}

3.修改后的 CMakeLists.txt 关键部分

# 在 "Programs:" 部分添加你的可执行文件（大约第 66 行附近）
if(NOT BUILD_MIDILIBRARY_ONLY)

  # 已有的工具列表...
  add_executable(textmidi tools/textmidi.cpp)
  add_executable(toascii tools/toascii.cpp)
  add_executable(tobin tools/tobin.cpp)
  
  # 添加你的自定义程序
  add_executable(fund2mid tools/fund2mid.cpp)  # 新增行

  # 继续原有工具列表...
  add_executable(tobinary tools/tobinary.cpp)
  add_executable(todec tools/todec.cpp)

# ...

# 在链接库部分添加（大约第 136 行附近）
  target_link_libraries(textmidi midifile)
  target_link_libraries(toascii midifile)
  target_link_libraries(tobin midifile)
  
  target_link_libraries(fund2mid midifile)  # 新增行

  target_link_libraries(tobinary midifile)
  target_link_libraries(todec midifile)

4.完整修改说明

文件结构要求：

midifile/
├── CMakeLists.txt
├── include/
├── src/
└── tools/
    ├── fund2mid.cpp      # 你的程序源码
    ├── createmidifile.cpp
    └── ...其他工具源码

必要修改点：

在 add_executable 列表中添加：
add_executable(fund2mid tools/fund2mid.cpp)
在 target_link_libraries 部分添加：
target_link_libraries(fund2mid midifile)

编译验证：

# 生成构建系统
mkdir build
cd build
cmake ..

# 编译项目（Windows）
cmake --build . --config Release

适配注意事项

C++ 标准要求：
# 建议升级到 C++17（修改第 4 行）
set(CMAKE_CXX_STANDARD 17)
