Something prepends /usr/bin to PATH (IEP-255)

When I try to run the build I get this error:

As you can see, the problem is that something prepends /usr/bin to PATH. This is not coming from my project environment settings, it starts with the second entry of the above.

Anybody seen this before? I spent hours looking through project settings and eclipse preferences, haven’t found anything. A grep -r in the project folder didn’t reveal any file containing /usr/bin apart from the project environment settings file.

HI @szekelyisz For unresolved errors, I would request you to create a new issue with the following logs.

Before you capture the logs, please create a new project from the templates and build the project.

1. Error log: https://github.com/espressif/idf-eclipse-plugin#error-log
2. Parser log: Project > C/C++ Index > Create Parser Log
3. Eclipse Environment info: https://github.com/espressif/idf-eclipse-plugin/blob/master/FAQ.md#how-do-i-provide-eclipse-envrionment-and-plugins-information

The cmake4eclipse project has very nice features like providers for automatic include directory discovery based on the CMakeLists.txt files and compiler built-in options. The latter will tell Eclipse about system header files that are not seen by the idf-eclipse-plugin for now.

@szekelyisz theoretically, same should be the case with this plugin, as it obtains information about include paths and preprocessor flags from compile_commands.json, generated by CMake. If for some reason indexing is not working for you, we can try to investigate.
