[This bug is NOT targeted to the upcoming trixie release] Please keep this issue open in the bug tracker for the package it was filed for. If a fix in another package is required, please file a bug for the other package (or clone), and add a block in this package. Please keep the issue open until the package can be built in a follow-up test rebuild. The package fails to build in a test rebuild on at least amd64 with gcc-15/g++-15, but succeeds to build with gcc-14/g++-14. The severity of this report will be raised before the forky release. The full build log can be found at: http://qa-logs.debian.net/2025/02/16/amd64exp/slrn_1.0.3+dfsg-8_unstable_gccexp.log.gz The last lines of the build log are at the end of this report. To build with GCC 15, either set CC=gcc-15 CXX=g++-15 explicitly, or install the gcc, g++, gfortran, ... packages from experimental. apt-get -t=experimental install g++ GCC 15 now defaults to the C23/C++23 standards, exposing many FTBFS. Other Common build failures are new warnings resulting in build failures with -Werror turned on, or new/dropped symbols in Debian symbols files. For other C/C++ related build failures see the porting guide at http://gcc.gnu.org/gcc-15/porting_to.html [...] /usr/include/uudeview.h:191:18: note: declared here 191 | int UUEXPORT UUSetOption _ANSI_ARGS_((int, int, char *)); | ^~~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:4587:27: error: too many arguments to function ‘UULoadFile’; expected 0, have 3 4587 | if (UURET_OK != (ret = UULoadFile (file, NULL, 0))) | ^~~~~~~~~~ ~~~~ /usr/include/uudeview.h:208:18: note: declared here 208 | int UUEXPORT UULoadFile _ANSI_ARGS_((char *, char *, int)); | ^~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:4592:29: error: too many arguments to function ‘UUGetOption’; expected 0, have 4 4592 | file, UUGetOption (UUOPT_ERRNO, NULL, NULL, 0)); | ^~~~~~~~~~~ ~~~~~~~~~~~ /usr/include/uudeview.h:190:18: note: declared here 190 | int UUEXPORT UUGetOption _ANSI_ARGS_((int, int *, char *, int)); | ^~~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:4594:58: error: too many arguments to function ‘UUstrerror’; expected 0, have 1 4594 | slrn_error (_("could not load %s: %s"), file, UUstrerror (ret)); | ^~~~~~~~~~ ~~~ /usr/include/uudeview.h:192:18: note: declared here 192 | char * UUEXPORT UUstrerror _ANSI_ARGS_((int)); | ^~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:4598:27: error: too many arguments to function ‘UUGetFileListItem’; expected 0, have 1 4598 | while (NULL != (item = UUGetFileListItem (i))) | ^~~~~~~~~~~~~~~~~ ~ /usr/include/uudeview.h:210:18: note: declared here 210 | uulist *UUEXPORT UUGetFileListItem _ANSI_ARGS_((int)); | ^~~~~~~~~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:4605:15: error: too many arguments to function ‘UUDecodeFile’; expected 0, have 2 4605 | ret = UUDecodeFile (item, NULL); | ^~~~~~~~~~~~ ~~~~ /usr/include/uudeview.h:214:18: note: declared here 214 | int UUEXPORT UUDecodeFile _ANSI_ARGS_((uulist *, char *)); | ^~~~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:4614:25: error: too many arguments to function ‘UUstrerror’; expected 0, have 1 4614 | else err = UUstrerror (ret); | ^~~~~~~~~~ ~~~ /usr/include/uudeview.h:192:18: note: declared here 192 | char * UUEXPORT UUstrerror _ANSI_ARGS_((int)); | ^~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:4621:1: warning: no return statement in function returning non-void [-Wreturn-type] 4621 | } | ^ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c: In function ‘view_scores’: /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:5574:48: warning: cast discards ‘const’ qualifier from pointer target type [-Wcast-qual] 5574 | if (slrn_edit_file (Slrn_Editor_Score, (char *) hlp->filename, | ^ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c: In function ‘find_children_headers’: /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:5978:4: warning: format not a string literal, argument types not checked [-Wformat-nonliteral] 5978 | slrn_message_now (fmt, meter_chars[last_meter_char]); | ^~~~~~~~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:5997:9: warning: format not a string literal, argument types not checked [-Wformat-nonliteral] 5997 | slrn_message_now (fmt, meter_chars[last_meter_char]); | ^~~~~~~~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c: In function ‘gen_cancel_key’: /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:3688:11: warning: ignoring return value of ‘fread’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 3688 | (void) fread (buf, filelen, 1, cansecret); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c: In function ‘display_article_line’: /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:8991:12: warning: this statement may fall through [-Wimplicit-fallthrough=] 8991 | if (Slrn_Verbatim_Marks_Hidden) | ^ /build/reproducible-path/slrn-1.0.3+dfsg/src/art.c:8994:7: note: here 8994 | case VERBATIM_LINE: | ^~~~ make[2]: *** [Makefile:225: /build/reproducible-path/slrn-1.0.3+dfsg/src/objs/art.o] Error 1 make[2]: Leaving directory '/build/reproducible-path/slrn-1.0.3+dfsg/src' make[1]: *** [debian/rules:12: override_dh_auto_build] Error 2 make[1]: Leaving directory '/build/reproducible-path/slrn-1.0.3+dfsg' make: *** [debian/rules:8: build] Error 2 dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2
