安装工具链的标准流程可以通过阅读文档 :doc:`Linux 平台工具链的标准设置 <linux-setup>` 来获得，:ref:`工具链的自定义设置 <get-started-customized-setup>` 章节会介绍哪些情况下我们必须要重新定义工具链。

安装必要的工具

==============

要想使用 ESP-IDF 进行编译，您需要获取以下软件包：
|
|
|
|
|
|
|
|
|
|
|
|
- Ubuntu 和 Debian::
|
|
|
|
|
|
|
2019-12-16 05:41:28 -05:00
|
|
|
|
sudo apt-get install gcc git wget make libncurses-dev flex bison gperf python python-pip python-setuptools python-serial python-cryptography python-future python-pyparsing libffi-dev libssl-dev
|
2018-08-15 22:31:04 -04:00
|
|
|
|
|
|
|
|
|
|
- Arch::
|
|
|
|
|
|
|
2019-03-01 04:50:16 -05:00
|
|
|
|
sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pyserial python2-cryptography python2-future python2-pyparsing
|
2018-08-15 22:31:04 -04:00
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
|
|
|
|
|
|
|
一些旧的（2014年之前）Linux 发行版中使用的 ``pyserial`` 版本可能是 2.x ， ESP-IDF并不支持。
|
|
|
|
|
|
在这种情况下，请参考 :ref:`安装依赖的 Python 软件包 <get-started-get-packages>` 章节，通过 ``pip`` 工具来安装支持的版本。
|
|
|
|
|
|
|
|
|
|
|
|
从源代码编译工具链
|
|
|
|
|
|
==================
|
|
|
|
|
|
|
|
|
|
|
|
- 安装依赖:
|
|
|
|
|
|
|
|
|
|
|
|
- CentOS 7::
|
|
|
|
|
|
|
|
|
|
|
|
sudo yum install gawk gperf grep gettext ncurses-devel python python-devel automake bison flex texinfo help2man libtool
|
|
|
|
|
|
|
|
|
|
|
|
- Ubuntu pre-16.04::
|
|
|
|
|
|
|
|
|
|
|
|
sudo apt-get install gawk gperf grep gettext libncurses-dev python python-dev automake bison flex texinfo help2man libtool
|
|
|
|
|
|
|
|
|
|
|
|
- Ubuntu 16.04::
|
|
|
|
|
|
|
|
|
|
|
|
sudo apt-get install gawk gperf grep gettext python python-dev automake bison flex texinfo help2man libtool libtool-bin
|
|
|
|
|
|
|
|
|
|
|
|
- Debian 9::
|
|
|
|
|
|
|
|
|
|
|
|
sudo apt-get install gawk gperf grep gettext libncurses-dev python python-dev automake bison flex texinfo help2man libtool libtool-bin
|
|
|
|
|
|
|
|
|
|
|
|
- Arch::

|
|
|
|
新建工作目录，然后进入::
|
|
|
|
|
|
|
|
|
|
|
|
mkdir -p ~/esp
|
|
|
|
|
|
cd ~/esp
|
|
|
|
|
|
|
|
|
|
|
|
|
2018-08-29 09:30:03 -04:00
|
|
|
|
下载 ``crosstool-NG`` 然后编译:
|
2018-08-15 22:31:04 -04:00
|
|
|
|
|
2018-08-29 09:30:03 -04:00
|
|
|
|
.. include:: /_build/inc/scratch-build-code.inc
|
2018-08-15 22:31:04 -04:00
|
|
|
|
|
|
|
|
|
|
编译工具链::
|
|
|
|
|
|
|
|
|
|
|
|
./ct-ng xtensa-esp32-elf
|
|
|
|
|
|
./ct-ng build
|
|
|
|
|
|
chmod -R u+w builds/xtensa-esp32-elf
|
|
|
|
|
|
|
|
|
|
|
|
编译得到的工具链会被保存到 ``~/esp/crosstool-NG/builds/xtensa-esp32-elf``。根据 :ref:`Linux 下设置环境变量的标准方法 <setup-linux-toolchain-add-it-to-path>` 中的介绍，将工具链添加到 ``PATH`` 中。
