For 11.0 -r300904 using devel/powerpc64-gcc on powerpc64 (not building = clang) I get the failures: > --- all_subdir_usr.bin --- . . . (some warnings) . . . > stdarg.h(40): syntax error [249] > stdarg.h(98): syntax error [249] > llib-lposix(307): syntax error [249] > llib-lposix(308): syntax error [249] > llib-lposix(309): syntax error [249] > llib-lposix(309): cannot recover from previous errors [224] > *** [llib-lposix.ln] Error code 1 >=20 > make[5]: stopped in /usr/src/usr.bin/xlint/llib > 1 error The 3 llib-lposix lines happen to be the lines using va_list: > int (vfprintf)(FILE *stream, const char *format, va_list arg); > int (vprintf)(const char *format, va_list arg); > int (vsprintf)(char *s, const char *format, va_list arg); As for stdarg.h (va_list related text will end up being involved as = well): > # ls -l /usr/include/stdarg.h=20 > lrwxr-xr-x 1 root wheel 16 May 23 21:22 /usr/include/stdarg.h -> = machine/stdarg.h > # ls -l = /usr/obj/xtoolchain/powerpc.powerpc64/usr/src/tmp/usr/include/stdarg.h > lrwxr-xr-x 1 root wheel 16 May 27 16:59 = /usr/obj/xtoolchain/powerpc.powerpc64/usr/src/tmp/usr/include/stdarg.h = -> machine/stdarg.h There is also: /usr/local/lib/gcc/powerpc64-portbld-freebsd11.0/5.3.0/include/stdarg.h (which seems to be the one in use). The usr/include/stdarg.h line 40's in each case are the #endif in: > #ifndef _VA_LIST_DECLARED > #define _VA_LIST_DECLARED > typedef __va_list va_list; > #endif By contrast the 5.3.0/include/stdarg.h has the typedef below as line 40: > #ifndef __GNUC_VA_LIST > #define __GNUC_VA_LIST > typedef __builtin_va_list __gnuc_va_list; > #endif usr/include/stdarg.h line 98 in each case is the sizeof line in: > #define __va_longlong(type) = \ > (__builtin_classify_type(*(type *)0) =3D=3D = __INTEGER_TYPE_CLASS && \ > sizeof(type) =3D=3D 8) By contrast the 5.3.0/include/stdarg.h has the typedef below as line 98: > #ifndef __va_list__ > typedef __gnuc_va_list va_list; > #endif /* not __va_list__ */ It would appear that = /usr/local/lib/gcc/powerpc64-portbld-freebsd11.0/5.3.0/include/stdarg.h = is the one in use during the failure. =3D=3D=3D Mark Millard markmi at dsl-only.net
