Error Build All - 5.1 LCD RGB Example - using 2.9.1 Eclipse IDF IDE (IEP-1013)

[marcusobrien]

Describe the bug
The Build All of the RGB LCD exmaple fails when building inside the IDE, it fails after compiling the RGB LCD example.

The error looks like one of the arguments to the size checker has been set to null, and therefore it fails.

I am running the IDE from In Windows 10, but if I run an esp-idf terminal and then cd into the project folder

cd D:\workspaces2022\Espressif_IDE2.9.1\rgb_panel
then run
idf.py build
It builds perfectly.

To Reproduce
Steps to reproduce the behavior:

1. Run an ESP-IDF 5.1 command shell
2. Run the IDE exe eg. espressif-ide.exe
3. Import the example folder from the Espressif 5.1 examples \Espressif\frameworks\esp-idf-v5.1\examples\peripherals\lcd\rgb_panel
4. Build All fails
5. Errors shown in Problem Occured Dialog

Errors occurred during the build.
Errors running builder 'CDT Core Builder' on project 'rgb_panel'.
Building rgb_panel
java.lang.NullPointerException
Building rgb_panel
java.lang.NullPointerException

8. Error is shown in Console

I can see this problematic line

null U:\Tools\Espressif\frameworks\esp-idf-v5.1\tools\idf_size.py

Note if I do the following it works fine in the same folder, with the same project - just from running the idf.py build from the command line

1. Run an ESP-IDF 5.1 command shell
2. Change to the project folder
   cd U:\Tools\Espressif\frameworks\esp-idf-v5.1\examples\peripherals\lcd\rgb_panel
3. run idf.py build

Expected behavior
Build All should work with no failures

Hi @marcusobrien,

thank you for reporting this. Have you installed the Espressif IDE from the Windows offline installer? In that case, tools should be picked up automatically, but otherwise, tools have to be installed via IDE like this https://github.com/espressif/idf-eclipse-plugin#installing-esp-idf-tools.

ESP-IDF version cannot be checked. IDF_PATH or IDF_PYTHON_ENV_PATH are not set.
Python set for IDF_PYTHON_ENV:

It looks like environment variables inside the IDE are not set. They should be set after tools installation from the IDE. You can check them by clicking:
Window -> Preferences -> C/C++ -> Environment
Let me know if that helps
