ubuntu 安装 g++

---

前提

安装 tflite_support 报错

error: subprocess-exited-with-error
RuntimeError: Unsupported compiler -- at least C++11 support is needed!

一、安装 g++

1.1 安装

# 安装编译工具链（如g++）和依赖库
sudo apt-get update
sudo apt-get install -y build-essential libstdc++6 g++-9  # 安装g++9或更高版本

• gcc（GNU C编译器）：用于编译C语言程序。
• g++（GNU C++编译器）：用于编译C++语言程序。
• make：用于构建程序，通过读取Makefile文件来自动化编译过程。

1.2 验证

安装 g++ 会自动安装 gcc，因为 g++ 依赖于 gcc 的核心功能
