Hi Deb, After switching over to meson the __FILE__macro adds '../utils/v4l2-tracer/' to the filename (since it is compiling from a relative path). It is nicer to use __FILE_NAME__ instead of __FILE__, but that is not available for every compiler. See https://git.linuxtv.org/v4l-utils.git/commit/?id=de7b731c4d4a191a530322d7c6dc42ba9c7c16d8 v4l2-tracer uses __FILE__ a lot, but that really should be modified to use a macro, just like v4l2-compliance etc. do. It's generally one of these two variants: utils/v4l2-tracer/trace-helper.cpp: fprintf(stderr, "%s:%s:%d: ", __FILE__, __func__, __LINE__); utils/v4l2-tracer/trace-helper.cpp: fprintf(stderr, "%s:%s:%d\n", __FILE__, __func__, __LINE__); It's rather ugly to see that duplicated some 60+ times. Can you replace it with a macro or something? And use __FILE_NAME__ in the macro? No hurry, but this definitely can be improved. Regards, Hans
