Installing Eclipse IDE
|
|
======================
|
|
|
|
The Eclipse IDE gives you a graphical integrated development environment for writing, compiling and debugging ESP-IDF projects.
|
|
|
|
* Start by installing the esp-idf for your platform (see files in this directory with steps for Windows, OS X, Linux).
|
|
|
|
* We suggest building a project from the command line first, to get a feel for how that process works. You also need to use the command line to configure your esp-idf project (via ``make menuconfig``), this is not currently supported inside Eclipse.
|
|
|
|
* Download the Eclipse Installer for your platform from eclipse.org_.
|
|
|
|
* When running the Eclipse Installer, choose "Eclipse for C/C++ Development" (in other places you'll see this referred to as CDT.)
|
|
|
|
Windows Users
|
|
=============
|
|
|
|
Using ESP-IDF with Eclipse on Windows requires different configuration steps. :ref:`See the Eclipse IDE on Windows guide <eclipse-windows-setup>`.
|
|
|
|
Setting up Eclipse
|
|
==================
|
|
|
|
Once your new Eclipse installation launches, follow these steps:
|
|
|
|
Import New Project
|
|
------------------
|
|
|
|
* Eclipse makes use of the Makefile support in ESP-IDF. This means you need to start by creating an ESP-IDF project. You can use the idf-template project from github, or open one of the examples in the esp-idf examples subdirectory.
|
|
|
|
* Once Eclipse is running, choose File -> Import...
|
|
|
|
* In the dialog that pops up, choose "C/C++" -> "Existing Code as Makefile Project" and click Next.
|
|
|
|
* On the next page, enter "Existing Code Location" to be the directory of your IDF project. Don't specify the path to the ESP-IDF directory itself (that comes later). The directory you specify should contain a file named "Makefile" (the project Makefile).
|
|
|
|
* On the same page, under "Toolchain for Indexer Settings" choose "Cross GCC". Then click Finish.
|
|
|
|
|
|
Project Properties
|
|
------------------
|
|
|
|
* The new project will appear under Project Explorer. Right-click the project and choose Properties from the context menu.
|
|
|
|
* Click on the "Environment" properties page under "C/C++ Build". Click "Add..." and enter name ``BATCH_BUILD`` and value ``1``.
|
|
|
|
* Click "Add..." again, and enter name ``IDF_PATH``. The value should be the full path where ESP-IDF is installed.
|
|
|
|
* Edit the ``PATH`` environment variable. Keep the current value, and append the path to the Xtensa toolchain installed as part of IDF setup, if this is not already listed on the PATH. A typical path to the toolchain looks like ``/home/user-name/esp/xtensa-esp32-elf/bin``. Note that you need to add a colon ``:`` before the appended path.
|
|
|
|
* On macOS, add a ``PYTHONPATH`` environment variable and set it to ``/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages``. This is so that the system Python, which has pyserial installed as part of the setup steps, overrides any built-in Eclipse Python.
|
|
|
|
Navigate to "C/C++ General" -> "Preprocessor Include Paths" property page:
|
|
|
|
* Click the "Providers" tab
|
|
|
|
* In the list of providers, click "CDT Cross GCC Built-in Compiler Settings". Under "Command to get compiler specs", replace the text ``${COMMAND}`` at the beginning of the line with ``xtensa-esp32-elf-gcc``. This means the full "Command to get compiler specs" should be ``xtensa-esp32-elf-gcc ${FLAGS} -E -P -v -dD "${INPUTS}"``.
|
|
|
|
* In the list of providers, click "CDT GCC Build Output Parser" and type ``xtensa-esp32-elf-`` at the beginning of the Compiler command pattern. This means the full Compiler command pattern should be ``xtensa-esp32-elf-(g?cc)|([gc]\+\+)|(clang)``
|

.. _eclipse-build-project:
|
|
|
|
Building in Eclipse
|
|
-------------------
|
|
|
|
Before your project is first built, Eclipse may show a lot of errors and warnings about undefined values. This is because some source files are automatically generated as part of the esp-idf build process. These errors and warnings will go away after you build the project.
|
|
|
|
* Click OK to close the Properties dialog in Eclipse.
|
|
|
|
* Outside Eclipse, open a command line prompt. Navigate to your project directory, and run ``make menuconfig`` to configure your project's esp-idf settings. This step currently has to be run outside Eclipse.
|
|
|
|
*If you try to build without running a configuration step first, esp-idf will prompt for configuration on the command line - but Eclipse is not able to deal with this, so the build will hang or fail.*
|
|
|
|
* Back in Eclipse, choose Project -> Build to build your project.
|
|
|
|
**TIP**: If your project had already been built outside Eclipse, you may need to do a Project -> Clean before choosing Project -> Build. This is so Eclipse can see the compiler arguments for all source files. It uses these to determine the header include paths.
|
|
|
|
Flash from Eclipse
|
|
------------------
|
|
|
|
You can integrate the "make flash" target into your Eclipse project to flash using esptool.py from the Eclipse UI:
|
|
|
|
* Right-click your project in Project Explorer (important to make sure you select the project, not a directory in the project, or Eclipse may find the wrong Makefile.)
|
|
|
|
* Select Build Targets -> Create... from the context menu.
|
|
|
|
* Type "flash" as the target name. Leave the other options as their defaults.
|
|
|
|
* Now you can use Project -> Build Target -> Build (Shift+F9) to build the custom flash target, which will compile and flash the project.
|
|
|
|
Note that you will need to use "make menuconfig" to set the serial port and other config options for flashing. "make menuconfig" still requires a command line terminal (see the instructions for your platform.)
|
|
|
|
Follow the same steps to add ``bootloader`` and ``partition_table`` targets, if necessary.
