While cross compiling on ARM32 , the casting from pointer to __u64 will cause warnings: samples/bpf/task_fd_query_user.c: In function 'main': samples/bpf/task_fd_query_user.c:399:23: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] 399 | uprobe_file_offset = (__u64)main - (__u64)&__executable_start; | ^ samples/bpf/task_fd_query_user.c:399:37: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] 399 | uprobe_file_offset = (__u64)main - (__u64)&__executable_start; Workaround this by using "unsigned long" to adapt to different ARCHs.
