test_txrx_hwloop.c / bladeRF build error on Raspberry Pi 4 B (bullseye 32bit)

I have the following error during the build:

Code: Select all

A year ago it was building just fine...

Why don't you contact support directly. Any problemsbasketball stars will be resolved faster.

The error you get while building the code is due to a change in the way the compiler handles warnings. Specifically, the current compiler is warning that the comparison >= 0 with variable c will always be true due to the data type of variable c. This error is raised to an error because the -Werror option is enabled, which turns all warnings into errors. slice master
