Reinette reported following compilation issue on Fedora 32, gcc version 10.1.1 /usr/bin/ld: cqm_test.o:<src_dir>/cqm_test.c:22: multiple definition of `cache_size'; cat_test.o:<src_dir>/cat_test.c:23: first defined here The same issue is reported for long_mask, cbm_mask, count_of_bits etc variables as well. Compiler isn't happy because these variables are defined globally in two .c files namely cqm_test.c and cat_test.c and the compiler during compilation finds that the variable is already defined (multiple definition error). Taking a closer look at the usage of these variables reveals that these variables are used only locally in functions such as cqm_resctrl_val() (defined in cqm_test.c) and cat_perf_miss_val() (defined in cat_test.c). These variables are not shared between those functions. So, there is no need for these variables to be global. Hence, fix this issue by making them static variables.
