clang complains: debuginfod.cxx:354:1: error: unused variable 'apba__' [-Werror,-Wunused-const-variable] ARGP_PROGRAM_BUG_ADDRESS_DEF = PACKAGE_BUGREPORT; ^ ../lib/printversion.h:47:21: note: expanded from macro 'ARGP_PROGRAM_BUG_ADDRESS_DEF' const char *const apba__ __asm ("argp_program_bug_address") ^
This is as expected: it's used by argp via the "argp_program_bug_address" name, which is not visible on the C level. Add __attribute__ ((used)) to make sure that the compiler emits it.
