Hi, Compiling a gnulib testdir on Solaris/x86 with Sun C, I get these errors:
cc -O -xc99=all -DHAVE_CONFIG_H -DEXEEXT=\"\" -DEXEEXT=\"\" -DNO_XMALLOC -DEXEEXT=\"\" -I. -I.. -I../intl -I/home/haible/prefix-x86/include -D_REENTRANT -g -c -o xstrtoll.o xstrtoll.c "xstrtol.c", line 49: undefined symbol: LONG_LONG_MIN "xstrtol.c", line 54: undefined symbol: LONG_LONG_MAX cc: acomp failed for xstrtoll.c *** Error code 2 cc -O -xc99=all -DHAVE_CONFIG_H -DEXEEXT=\"\" -DEXEEXT=\"\" -DNO_XMALLOC -DEXEEXT=\"\" -I. -I.. -I../intl -I/home/haible/prefix-x86/include -D_REENTRANT -g -c -o xstrtoull.o xstrtoull.c "xstrtol.c", line 54: undefined symbol: ULONG_LONG_MAX cc: acomp failed for xstrtoull.c *** Error code 2 The reason is that the files strtol.c, xstrtoll.c, lib/xstrtoull.c use the macros LONG_LONG_MIN, LONG_LONG_MAX, ULONG_LONG_MAX. But these macros are not standard. ISO C99 and POSIX specify that <limits.h> defines LLONG_MIN, LLONG_MAX, ULLONG_MAX. The macros LONG_LONG_MIN, LONG_LONG_MAX, ULONG_LONG_MAX come from gcc's <limits.h>: #if defined (__GNU_LIBRARY__) ? defined (__USE_GNU) : !defined (__STRICT_ANSI__) /* Minimum and maximum values a `signed long long int' can hold. */ # undef LONG_LONG_MIN # define LONG_LONG_MIN (-LONG_LONG_MAX - 1LL) # undef LONG_LONG_MAX # define LONG_LONG_MAX __LONG_LONG_MAX__ /* Maximum value an `unsigned long long int' can hold. (Minimum is 0). */ # undef ULONG_LONG_MAX # define ULONG_LONG_MAX (LONG_LONG_MAX * 2ULL + 1ULL) #endif As you can see, these are not even defined with "gcc -ansi". Suggestions? Should we use LLONG_MIN or better rely on the macros from <stdint.h>? Bruno
