 # Linux

 - Install gcc and qt5
- - Use qtcreator to open Red_Panda_CPP.pro
+ - Open `Red_Panda_CPP.pro` with Qt Creator
+
+qmake variables:
+- `PREFIX`: default to `/usr/local`. It should be set to `/usr` or `/opt/redpanda-cpp` when packaging.
+- `LIBEXECDIR`: directory for auxiliary executables, default to `$PREFIX/libexec`. Arch Linux uses `/usr/lib`.
+
+## Ubuntu
+
+### 1. Install Compiler
+
+```bash
+apt install gcc g++ make gdb gdbserver
+```
+
+### 2. Install Qt 5 and Other Dependencies
+
+```bash
+apt install qtbase5-dev qttools5-dev-tools libicu-dev libqt5svg5-dev git qterminal
+```
+
+### 3. Fetch Source Code
+
+```bash
+git clone https://github.com/royqh1979/RedPanda-CPP.git
+```
+
+### 4. Build
+
+```bash
+cd RedPanda-CPP/
+qmake Red_Panda_CPP.pro
+make -j$(nproc)
+sudo make install
+```
+
+### 5. Run
+
+```bash
+RedPandaIDE
+```
+
+## Arch Linux
+
+A reference PKGBUILD is available at `packages/archlinux`. Build RedPanda C++ with [makepkg](https://wiki.archlinux.org/title/Makepkg) and then install.
+
+Enter `RedPandaIDE` to launch RedPanda C++.
+
+Note that makepkg checks out HEAD of the repo, so any change should be committed before building.
+
+## AppImage
+
+1. Install dependency: cURL, Docker.
+
+   Extra requirements for Windows host:
+   - Docker uses WSL 2 based engine, or enable file sharing on the project folder (Settings > Resources > File sharing);
+   - PowerShell (previously “PowerShell Core”, not “Windows PowerShell”).
+2. Prepare build environment. Linux host:
+   ```bash
+   arch=x86_64 # or aarch64
+   curl -L -o packages/appimage/dockerfile-$arch/appimagetool-$arch.AppImage https://github.com/AppImage/AppImageKit/releases/download/13/appimagetool-$arch.AppImage
+   docker build -t redpanda-builder-$arch packages/appimage/dockerfile-$arch
+   ```
+   Windows host:
+   ```ps1
+   $arch = "x86_64" # or "aarch64" someday Docker is available on WoA
+   Invoke-WebRequest -OutFile packages/appimage/dockerfile-$arch/appimagetool-$arch.AppImage -Uri https://github.com/AppImage/AppImageKit/releases/download/13/appimagetool-$arch.AppImage
+   docker build -t redpanda-builder-$arch packages/appimage/dockerfile-$arch
+   ```
+3. Build AppImage. Linux host:
+   ```bash
+   ./packages/appimage/build-x86_64.sh # or *-aarch64.sh
+   ```
+   Windows host:
+   ```ps1
+   ./packages/appimage/build-x86_64.ps1 # or *-aarch64.ps1 someday Docker is available on WoA
+   ```
+4. Run Red Panda C++.
+   ```bash
+   ./dist/RedPandaIDE-x86_64.AppImage # or *-aarch64.AppImage
+   ```
+
+Note: AppImage, in which format AppImageKit is shipped, is incompatable with QEMU user space emulator, so you cannot build AArch64 AppImage on x86-64, and vice versa.

+## Arch Linux 及衍生版本
+
+`packages/archlinux` 目录下提供了一个参考 PKGBUILD，使用 [makepkg](https://wiki.archlinuxcn.org/wiki/Makepkg) 构建小熊猫 C++ 并安装。
+
+小熊猫 C++ 可以通过 `RedPandaIDE` 命令启动。
+
+注意：makepkg 签出此存储库的 HEAD，因此构建之前务必提交所有变更。
+
+## AppImage
+
+1. 安装依赖包：cURL、Docker。
+
+   Windows 宿主的额外要求：
+   - Docker 使用基于 WSL 2 的引擎，或者对此项目文件夹启用文件共享（Settings > Resources > File sharing）；
+   - PowerShell（曾用名 “PowerShell Core”，不是 “Windows PowerShell”）。
+2. 准备构建环境。Linux 宿主：
+   ```bash
+   arch=x86_64 # 或 aarch64
+   curl -L -o packages/appimage/dockerfile-$arch/appimagetool-$arch.AppImage https://github.com/AppImage/AppImageKit/releases/download/13/appimagetool-$arch.AppImage
+   docker build -t redpanda-builder-$arch packages/appimage/dockerfile-$arch
+   ```
+   Windows 宿主：
+   ```ps1
+   $arch = "x86_64" # 或 "aarch64"（如果将来 Docker 支持 WoA）
+   Invoke-WebRequest -OutFile packages/appimage/dockerfile-$arch/appimagetool-$arch.AppImage -Uri https://github.com/AppImage/AppImageKit/releases/download/13/appimagetool-$arch.AppImage
+   docker build -t redpanda-builder-$arch packages/appimage/dockerfile-$arch
+   ```
+3. 构建 AppImage。Linux 宿主：
+   ```bash
+   ./packages/appimage/build-x86_64.sh # 或 *-aarch64.sh
+   ```
+   Windows 宿主：
+   ```ps1
+   ./packages/appimage/build-x86_64.ps1 # 或 *-aarch64.ps1（如果将来 Docker 支持 WoA）
+   ```
+4. 运行小熊猫 C++.
+   ```bash
+   ./dist/RedPandaIDE-x86_64.AppImage # 或 *-aarch64.AppImage
+   ```
+
+注意：AppImage 与 QEMU 用户态模拟不兼容，使用此格式的 AppImageKit 工具自然不能用 QEMU 用户态模拟来运行。因此不能在 x86-64 系统上构建 AArch64 AppImage，反之亦然。
