hi, Spurious redefinition of _FILE_OFFSET_BITS trigger many warnings when using gcc in Solaris. Adding an undef before redefining would clear the problem.
It is initially defined in gcc/lib/gcc/i386-pc-solaris2.11/4.3.2/include-fixed/sys included by string.h. #if defined(_LP64) #ifndef _FILE_OFFSET_BITS #define _FILE_OFFSET_BITS 64 #endif #if _FILE_OFFSET_BITS - 0 != 64 #error "invalid _FILE_OFFSET_BITS value specified" #endif #else /* _LP64 */ #ifndef _FILE_OFFSET_BITS #define _FILE_OFFSET_BITS 32 #endif #if _FILE_OFFSET_BITS - 0 != 32 && _FILE_OFFSET_BITS - 0 != 64 #error "invalid _FILE_OFFSET_BITS value specified" #endif #endif /* _LP64 */ And here is the result of the configure script on the subject : configure:3376: checking for _FILE_OFFSET_BITS value needed for large files configure:3411: gcc -c -g -O2 conftest.c >&5 conftest.c:14: warning: left shift count >= width of type conftest.c:14: warning: left shift count >= width of type conftest.c:16: error: size of array 'off_t_is_large' is negative configure:3417: $? = 1 configure: failed program was: | /* confdefs.h. */ | #define PACKAGE_NAME "Scilab" | #define PACKAGE_TARNAME "scilab" | #define PACKAGE_VERSION "5" | #define PACKAGE_STRING "Scilab 5" | #define PACKAGE_BUGREPORT "http://bugzilla.scilab.org/"; | /* end confdefs.h. */ | #include <sys/types.h> | /* Check that off_t can represent 2**63 - 1 correctly. | We can't simply define LARGE_OFF_T to be 9223372036854775807, | since some C++ compilers masquerading as C compilers | incorrectly reject 9223372036854775807. */ | #define LARGE_OFF_T (((off_t) 1 << 62) - 1 + ((off_t) 1 << 62)) | int off_t_is_large[(LARGE_OFF_T % 2147483629 == 721 | && LARGE_OFF_T % 2147483647 == 1) | ? 1 : -1]; | int | main () | { | | ; | return 0; | } configure:3461: gcc -c -g -O2 conftest.c >&5 configure:3467: $? = 0 configure:3485: result: 64 Jonathan Blanchard
