从零开始设置 Linux 环境下的工具链
******************************************
:link_to_translation:`en:[English]`
除了从乐鑫官网直接下载已编译好的二进制工具链外,您还可以按照本文介绍,从头开始设置自己的工具链。如需快速使用已编译好的二进制工具链,可回到 :doc:`linux-setup` 章节。
安装准备
=====================
编译 ESP-IDF 需要以下软件包:
- CentOS 7::
sudo yum install git wget ncurses-devel flex bison gperf python pyserial python-pyelftools cmake ninja-build ccache dfu-util
- Ubuntu 和 Debian::
sudo apt-get install git wget libncurses-dev flex bison gperf python python-pip python-setuptools python-serial python-click python-cryptography python-future python-pyparsing python-pyelftools cmake ninja-build ccache libffi-dev libssl-dev dfu-util
- Arch::
sudo pacman -S --needed gcc git make ncurses flex bison gperf python-pyserial python-click python-cryptography python-future python-pyparsing python-pyelftools cmake ninja ccache dfu-util
.. note::
使用 ESP-IDF 需要 CMake 3.5 或以上版本。较早版本的 Linux 可能需要升级才能向后移植仓库,或安装 "cmake3" 软件包,而不是安装 "cmake"。
从源代码编译工具链
=================================
安装依赖项:
- CentOS 7::
sudo yum install gawk gperf grep gettext ncurses-devel python python-devel automake bison flex texinfo help2man libtool make
- Ubuntu pre-16.04::
sudo apt-get install gawk gperf grep gettext libncurses-dev python python-dev automake bison flex texinfo help2man libtool make
- Ubuntu 16.04 或以上 ::
sudo apt-get install gawk gperf grep gettext python python-dev automake bison flex texinfo help2man libtool libtool-bin make
- Debian 9::
sudo apt-get install gawk gperf grep gettext libncurses-dev python python-dev automake bison flex texinfo help2man libtool libtool-bin make
- Arch::
TODO
创建工作目录,并进入该目录::
mkdir -p ~/esp
cd ~/esp
下载并编译 ``crosstool-NG``
.. include-build-file:: inc/scratch-build-code.inc
编译工具链::
./ct-ng xtensa-{IDF_TARGET_TOOLCHAIN_NAME}-elf
./ct-ng build
chmod -R u+w builds/xtensa-{IDF_TARGET_TOOLCHAIN_NAME}-elf
.. only:: esp32
编译得到的工具链会被保存到 ``~/esp/crosstool-NG/builds/xtensa-{IDF_TARGET_TOOLCHAIN_NAME}-elf``。请按照 :ref:`标准设置指南 <setup-linux-toolchain-add-it-to-path-legacy>` 的介绍,将工具链添加到 ``PATH``
