在 Windows 下使用 CMake + Visual Studio 2022 构建。
|
在 Windows 下使用 CMake + Visual Studio 2022 构建。
|
||||||
|
|
||||||
第一次构建前请到 `third-party/sqlite3` 目录下执行 `fetch_sqlite3.sh`，或手动下载源码放置到对应的位置。
|
|
||||||
|
|
||||||
然后就可以利用 CMake 构建了：
|
|
||||||
|
|
||||||
```cmd
|
```cmd
|
||||||
cmake --preset vs -DCMAKE_BUILD_TYPE=Release
|
cmake --preset vs -DCMAKE_BUILD_TYPE=Release
|
||||||
cmake --build --preset vs-release --config Release
|
cmake --build --preset vs-release --config Release

|
copy /y README.MD .\\build\\vs2022\\
|

```
|
```
|
||||||
|
|
||||||
### CMake 参数
|
|
||||||
|
|
||||||
CMake 支持以下参数：
|
|
||||||
|
|
||||||
- `USE_WIN_SQLITE3` - 使用 Windows 内置的 SQLite3 链接库（仅限 Windows + MSVC 编译环境）。
|
|
||||||
- `USE_WIN_CRYPTO` - 使用 Windows 内置的加密/哈希实现，而非软件实现（仅限 Windows 目标）。
|
|
||||||
- `USE_SYSTEM_SQLITE3` - 使用外部的 SQLite3 实现 (Debian: `libsqlite3-dev`)，找不到时会报错。
|
|
||||||
- `USE_OpenSSL` - 使用 OpenSSL 的加密/哈希实现 (Debian: `libssl-dev`)，找不到时会报错。
|
|
||||||
|
|
||||||
Ubuntu 下编译发布版，不使用外部库：
|
|
||||||
|
|
||||||
```sh
|
|
||||||
cmake -G "Ninja Multi-Config" -B build/linux-all -DUSE_SYSTEM_SQLITE3=0 -DUSE_OPENSSL=0
|
|
||||||
cmake --build build/linux-all --config Release -j
|
|
||||||
```
|
|
||||||
|
|
||||||
Ubuntu 下编译发布版，链接到现有的库：
|
|
||||||
|
|
||||||
```sh
|
|
||||||
cmake -G "Ninja Multi-Config" -B build/linux-ext -DUSE_SYSTEM_SQLITE3=1 -DUSE_OPENSSL=1
|
|
||||||
cmake --build build/linux-ext --config Release -j
|
|
||||||
```
|
|
||||||
|
|
||||||
### 第三方软件
|
|
||||||
|
|
||||||
该程序用到了以下第三方软件：
|
|
||||||
|
|
||||||
- [SQLite3](https://www.sqlite.org/) (Public Domain)
|
|
||||||
- [Tiny AES in C](https://github.com/kokke/tiny-AES-c) (Public Domain)
|
|
||||||
- [MD5.c](https://github.com/freebsd/freebsd-src/blob/release/14.2.0/sys/kern/md5c.c) (from FreeBSD)
|
|
||||||
- Derived from the "RSA Data Security, Inc. MD5 Message-Digest Algorithm".
|
|
||||||
|
|
||||||
### Windows 7 用户注意
|
|
||||||
|
|
||||||
请从 SQLite 官网下载 [`sqlite-dll-win-x64-*.zip`](https://www.sqlite.org/download.html#win32)
|
|
||||||
并将压缩包内的 `sqlite3.dll` 放置到 `kgg-dec.exe` 同目录下，并更名为 `winsqlite3.dll`。
|
|
||||||
|
|
||||||
Windows 10 或更新版本不需要此操作，因为 Windows 10 或以上的版本内置该文件。
