We suggest to choose Crosstool-ng as the compiler toolchain. Follow the instructions below to install Crosstool-ng.

Step 1. Install the required toolchain packages.

sudo apt-get install git autoconf build-essential gperf bison flex texinfo libtool libncurses5-dev wget gawk libc6-dev-i386 python-serial libexpat-dev

Step 2. Create a directory (e.g./opt/Espressif) to store the toolchain.

sudo mkdir /opt/Espressif

Step 3. Make the current user the owner.

sudo chown $USER /opt/Espressif/

Step 4. Download the latest toolchain installation file to the directory created in Step 2.

cd /opt/Espressif/git clone -b esp108-1.21.0 git://github.com/jcmvbkbc/crosstool-NG.git

Step 5. Install toolchain.

cd crosstool-NG./bootstrap && ./configure --prefix=`pwd` && make && make install ./ct-ng xtensa-esp108-elf ./ct-ng build

Step 6. Set the PATH variable to point to the newly compiled toolchain.

export PATH=/opt/Espressif/crosstool-NG/builds/xtensa-esp108-elf/bin:$PATH

Note： You need to do Step 6 once you open a new shell, or you can put it inside your .bashrc file

Project template Compile

Step 1. Create a directory (e.g.~/Workspace) to store a new project.

mkdir ~/Workspace

Step 2. Clone ESP32 RTOS SDK.

cd ~/Workspacegit clone https://github.com/espressif/ESP32_RTOS_SDK.git

Step 3. Copy ESP32_RTOS_SDK/examples/project_template to Workspace directory created in Step 1.

cp ~/Workspace/ESP32_RTOS_SDK/examples/project_template ~/Workspace/ -r

Step 4. Create a directory (e.g.~/Workspace/ESP32_BIN) to store the bin files compiled.

mkdir –p ~/Workspace/ESP32_BIN

Step 5. Set SDK_PATH as the path of SDK files and BIN_PATH as the path of .bin files compiled.

export SDK_PATH=~/Workspace/ESP32_RTOS_SDK export BIN_PATH=~/Workspace/ESP32_BIN

Notice： Make sure you set the correct paths, or it will occur a compile error.

Step 6. Start to compile files

cd ~/Workspace/project_templatemake cleanmake

Note： You need to do Step 3 every time you open a new shell, or you can put it inside your .bashrc file.

If your project is successfully compiled, the irom1.bin, irom0_flash.bin, and user.ota files will be generated in ~/Workspace/ESP32_BIN directory.
