of course, you can use Eclipse as IDE to compile the GUI examples of the Build Environments that we have provided for i.MX 6/7/8. However, for all Linux based Build Environments we only provide ready-to-use GCC/makefile projects - only in case of MCUs we support different IDEs. The reason is simple, because typically on Linux systems GCC/makefile is commonly used, whereas you will find different toolchains for MCUs (e.g. KEIL, IAR and Eclipse based IDEs).
You have to create your own Eclipse project, using GCC compiler/linker with the particular settings for your target. The project templates within our Build Environments are based on GCC/makefile - you can find all necessary settings within the makefile.
