Hi, libgcrypt20 fails to build from source with gcc-15 for some architectures. The cause may be found in mpi/longlong.h. In several lines such as 193, 499 and 1409, there are function prototypes without arguments. This trips up the updated language standard by gcc-15 and building libcrypt20 now complains about excess arguments. For example: | In file included from ../../mpi/mpih-div.c:32: | ../../mpi/mpih-div.c: In function ‘_gcry_mpih_mod_1’: | ../../mpi/longlong.h:190:11: error: too many arguments to function ‘__udiv_qrnnd’; expected 0, have 4 | 190 | (q) = __udiv_qrnnd (&__r, (n1), (n0), (d)); \ | | ^~~~~~~~~~~~ ~~~~ | ../../mpi/mpih-div.c:84:17: note: in expansion of macro ‘udiv_qrnnd’ | 84 | udiv_qrnnd(divisor_limb_inverted, dummy, | | ^~~~~~~~~~ | ../../mpi/longlong.h:193:16: note: declared here This does not seem to affect amd64 as Matthias would have otherwise reported this problem already. It does affect at least alpha. Remember that this problem does not affect trixie and that it can be worked around by exporting DEB_CFLAGS_APPEND=-std=gnu17. Hence, I recommend not fixing this before trixie is released. Helmut
