Eclipse installation under linux not working

[dawime]

Following the plugin installation instructions under:
https://github.com/espressif/idf-eclips ... /README.md

I get to creating a project using the template (hello_world), but the project won't build due to unresolved symbols related to the esp chip:
esp_chip_info_t chip_info; for example (can't find esp_chip_info_t)

I can access the header files (esp_system.h), but diving into it and trying to for example open esp_mac.h doesn't seem to find it.

Here is the output when I list the installed tools:
