Dwm-simple.c in Ubuntu Decawave VM Not Working

Hi there,

I launched the Decawave-DWM1001_Virtualbox_Image in Oracle VM Virtualbox as it is stated in https://www.decawave.com/wp-content/uploads/2018/08/dwm1001_firmware_user_guide.pdf.

Nevertheless, when i tried to compile the dwm-simple.c program, there are some errors in default Eclipse IDE which comes in the Ubuntu system :

-Program -E not found in PATH (C/C++ Scanner Discovery Problem)
-Symbol ‘NULL’ COULD NOT BE RESOLVED
-Type ‘uint32_t’ could not be resolved
-Type uint8_t could not be resolved

I tried every possible solution but could not manage to work with the sample code.
It would be great if anyone in here can help me.

I haven’t met the same problem, but maybe try the suggestions from:
