Setup Linux Toolchain from Scratch¶
The following instructions are alternative to downloading binary toolchain from Espressif website. To quickly setup the binary toolchain, instead of compiling it yourself, backup and proceed to section Linux 平台工具链的标准设置.
Install Prerequisites¶
To compile with ESP-IDF you need to get the following packages:
Ubuntu and Debian:
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
Arch:
sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pyserial python2-cryptography python2-future python2-pyparsing
Compile the Toolchain from Source¶
Install dependencies:
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 or newer:
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:
TODO
Download crosstool-NG
and build it:
cd ~/esp
git clone -b xtensa-1.22.x https://github.com/espressif/crosstool-NG.git
cd crosstool-NG
./bootstrap && ./configure --enable-local && make install
Build the toolchain:
./ct-ng xtensa-esp32-elf
./ct-ng build
chmod -R u+w builds/xtensa-esp32-elf
Toolchain will be built in ~/esp/crosstool-NG/builds/xtensa-esp32-elf
. Follow instructions for standard setup to add the toolchain to your PATH
.
Next Steps¶
To carry on with development environment setup, proceed to section 获取 ESP-IDF.
