如何在Linux Ubuntu上安装Flatc和FlatBuffers

Question

如果我们在Linux Ubuntu上安装平面缓冲区，将无法从任何地方使用shortc flatc命令进行编译，我们该怎么做？

例如：我想在package.json中使用一些命令 “ flatc -o path / src / app / core / providers / flatbuffers .....”

为了做到这一点还不足以安装平面缓冲区，我们还需要执行许多其他操作-添加符号链接等。

Answer 1

Olexandr的答案仅适用于Flatc二进制文件。

要使用cmake从源代码构建和安装所有平面缓冲区，请按照说明here：

• 克隆repo和cd flatbuffers
• 为linux ubuntu生成构建文件

cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release

• 编译

make

• 安装

sudo make install

Answer 2

在Ubuntu 20.04（重点）中，它已经在apt储存库中（https://packages.ubuntu.com/focal/flatbuffers-compiler），因此您可以直接安装它：

sudo apt update
sudo apt install -y flatbuffers-compiler

对于Ubuntu 18.04（仿生），您可以使用PPA（https://launchpad.net/~hnakamur/+archive/ubuntu/flatbuffers）：

sudo apt-add-repository ppa:hnakamur/flatbuffers
sudo apt update
sudo apt install -y flatbuffers-compiler

两者都比较老（1.11），但是如果您不使用最新功能，则应该非常可靠。

用于Linux ubuntu的flatc和flatbuffers的解决方案：

1. 选择“安装文件夹”
2. cd“安装文件夹”
3. git clone https://github.com/google/flatbuffers.git
4. cd平面缓冲区
5. cmake -G“ Unix Makefiles”（如果需要，请安装cmake）
6. 制作
7. sudo ln -s /全路径到flatbuffer / flatbuffers / flatc / usr / local / bin / flatc
8. chmod + x / full-path-to-flatbuffer / flatbuffers / flatc
9. 在任何地方以“ flatc”运行

Answer 4

这是使生活变得轻松的 CMake 文件。这些 cmake 命令将从 git repo 下载 flatbuffer 并安装在 linux 系统范围内访问。要在构建后安装，请运行“sudo make install”。
