I am trying to get cmocka unit testing to work but for some reason the linker does not accept multiple --wrap linker flags. I have seen people doing it this way at another post in stackoverflow. I am using gcc version 10.3.0 built by MSYS2 project on win10.
Just use:
add_executable(beTheLight-unit-tests main.c)
target_link_options(beTheLight-unit-tests PUBLIC
-Wl,--wrap=get_rx_dali_flag
-Wl,--wrap=set_led_frequency
-Wl,--wrap=application_process
)
on older cmake use target_link_libraries
. No need for set_target_properties
.
