Compiling the rtdoa_node and rtdoa_tag examples fails

[seijikun]

When compiling the rtdoa_node or the rtdoa_tag example, I get compile errors.

Software-Versions:

• uwb-apps: master
• gcc: 9.2.1 & 10.2.1
• mynewt: 1.8.0

Hardware: DWM1001

Error:

Adding "-Wno-error=address-of-packed-member" to the cflags of the two examples makes them compile, and it seems to work, at least.

Where exactly do you go to do this?
