[Bug bootstrap/25502] Werror problem in build
--- Comment #13 from aaronavay62 at aaronwl dot com 2008-05-11 03:04 --- What would be an acceptable solution other than having bootstrap perpetually broken, and other than --disable-werror? 1) We could only enable this warning when in strict mode, eg -std=c99 -pedantic. -std=gnu99 -pedantic would not warn. This seems like it might be best. 2) Adding __extension__ will silence this warning. Should we make a macro to decorate these uses of HOST_WIDEST_INT_PRINT_DEC? 3) Worse case, can we just HOST_WIDEST_INT long? -- aaronavay62 at aaronwl dot com changed: What|Removed |Added CC||aaronavay62 at aaronwl dot ||com Last reconfirmed|2005-12-23 05:44:30 |2008-05-11 03:04:43 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25502

IMO, that warning is valid and useful and should not be fixed. Danny -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25502

--- Comment #6 from rmathew at gcc dot gnu dot org 2006-06-04 09:47 --- By the way, x-mingw32 contains: # On MinGW, we use %IA64d to print 64-bit integers, and the format-checking # code does not handle that, so we have to disable checking here. WERROR_FLAGS += -Wno-format This should have fixed the problem, but it doesn't for some reason. See also: http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02223.html (and the follow-up messages). -- rmathew at gcc dot gnu dot org changed: What|Removed |Added CC||rmathew at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25502

--- Comment #7 from dannysmith at users dot sourceforge dot net 2006-06-04 11:02 --- In my local tree (and in the 3.4.x mingw tree), I have added a modification and extension of this patch: http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02296.html I plan to follow up in stage 1 of 4.3 This patch silences the worst of the warnings. However, because of the -pedantic switch, I still get warnings like ../../gcc/gcc/gcov-dump.c:408: warning: ISO C does not support the 'I64' printf length modifier -Wno-pedantic-errors doesn't work for me, so --disable-werror is still necessary. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25502

I can understand the why, but I don't think it should be required (because that means other warnings will not be spotted). There is no way around this; if you do not use the special Microsoft formats you will not get incorrect results; there are places where GCC must print a 64-bit integer, especially when configured with 64-bit HOST_WIDE_INTs, which is required for some targets. And anyway, it should at least be release-noted. Good idea! Care to submit a patch for the caveats page? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25502

--- Comment #3 from mmitchel at gcc dot gnu dot org 2005-12-20 16:44 --- This was discussed after I posted the patch. The GCC format-checking stuff does not know about the Windows extensions. So, on MinGW, you should --disable-werror. This bug should be reclassified as a diagnostic bug; it's a limitation in the format checkers, not a bug in the macros. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25502
