dh_dwz is not being helpful here. I managed to get this output with DH_VERBOSE=1: | dh_dwz -Nlibglib2.0-udeb | install -d debian/libglib2.0-0/usr/lib/debug/.dwz/aarch64-linux-gnu | dwz -q -mdebian/libglib2.0-0/usr/lib/debug/.dwz/aarch64-linux-gnu/libglib2.0-0.debug -M/usr/lib/debug/.dwz/aarch64-linux-gnu/libglib2.0-0.debug -- debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/glib-2.0/gio-launch-desktop debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/glib-2.0/gio-querymodules debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/glib-2.0/glib-compile-schemas debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/libgio-2.0.so.0.6000.6 debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/libglib-2.0.so.0.6000.6 debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/libgmodule-2.0.so.0.6000.6 debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/libgobject-2.0.so.0.6000.6 debian/libglib2.0-0/usr/lib/aarch64-linux-gnu/libgthread-2.0.so.0.6000.6 | dwz: Too few files for multifile optimization | aarch64-linux-gnu-objcopy --compress-debug-sections debian/libglib2.0-0/usr/lib/debug/.dwz/aarch64-linux-gnu/libglib2.0-0.debug | aarch64-linux-gnu-objcopy: 'debian/libglib2.0-0/usr/lib/debug/.dwz/aarch64-linux-gnu/libglib2.0-0.debug': No such file | dh_dwz: aarch64-linux-gnu-objcopy --compress-debug-sections debian/libglib2.0-0/usr/lib/debug/.dwz/aarch64-linux-gnu/libglib2.0-0.debug returned exit code 1 What is dh_dwz trying to tell me here? Kindly, dh_dwz passes -q. Doing so an important aspect. For each file passed, dwz without -q says ".debug_info section not present". What it is trying to convey here is that the build was performed without the "-g" option to gcc and no debug symbols were generated. Obvious, isn't it? I propose that after running dwz, the destination file is checked for existence. If it is missing, dh_dwz aborts rather than running objcopy. Before exiting with a failure dh_dwz should do one of two possible things: a) Run the same dwz invocation again. This time dropping -q. b) Check the passed objects for debug symbols and emit an appropriate message if they go missing. Helmut
