I'm trying port ugfx on nrf52840 nrf5_SDK 17.0.1 but only i added the make file getting lots for error.

[Ashwani Kesharwani]

I'm first time using this library not have much idea how can i port this because there is not a single example for that board. i'm adding my project here if you can check please go through it.

Hello!

Can you provide a bit more information regarding your environment? The errors you're getting certainly indicate that you didn't enable a GOS port (the main system abstraction layer). You can read more about that here: https://wiki.ugfx.io/index.php/GOS
If you're using zephyr there is an existing port:  https://wiki.ugfx.io/index.php/Zephyr
If you're using another underlying operating system such as FreeRTOS there are also existing ports for those.
If instead you're not using any underlying operating system (baremetal) you can use the Raw32 port: https://wiki.ugfx.io/index.php/BareMetal

Also, which build system are you using?

Hey,

It seems like you just copied the same compiler output as in your initial post. Please provide a bit more information as requested in my first post.
