[Clfs-support] issue about gcc and e2fsprogs

[Sela Selah]

In chapter 6.10, after modify the Makefile by sed:

If xxxLIBS & xxxINC = /tools/, make will results the header error.

If xxxLIBS & xxxINC = /cross-tools/, make will results the wrong lib format
error.

Only xxxLIBS = /tools/ && xxxINC=/cross-tools/, the compiling could
complete.

This issue I had meet ever. Now I do the compiling in a new platform
(hardware and os), the same issue remains.

 

In chapter 7.7

The compiling results error: conflict type.

in the build/lib/ext2fs/ext2_type.h, the _u64 typedef with unsigned long
long,

but in the kernel header, the _u64 typedef with unsigned long.

The type _s64 has similar comfliction

Maybe it's a e2fsprogs bug:

In file root/lib/ext2fs/ext2_types.h.in

Line 89, the comment about SIZEOF_LONG_LONG/SIZEOF_LONG is *NOT* consists
with the if-else branch:

#ifdef __U64_TYPEDEF

typedef __U64_TYPEDEF __u64;

#else

#if (@SIZEOF_INT@ == 8)

typedef unsigned int        __u64;

#else

#if (@SIZEOF_LONG_LONG@ == 8) // < ------- should long branch

typedef unsigned long long      __u64;

#else

#if (@SIZEOF_LONG@ == 8)

typedef unsigned long     __u64;  // < ------- should long long branch

#endif /* SIZEOF_LONG_LONG == 8 */

#endif /* SIZEOF_LONG == 8 */

#endif /* SIZEOF_INT == 8 */

#endif /* __U64_TYPEDEF */

 

#ifdef __S64_TYPEDEF

typedef __S64_TYPEDEF __s64;

#else

#if (@SIZEOF_INT@ == 8)

typedef int                 __s64;

#else

#if (@SIZEOF_LONG_LONG@ == 8)

#if defined(__GNUC__)    // < --------------- should long branch

typedef __signed__ long long __s64;

#else

typedef signed long long __s64;

#endif /* __GNUC__ */

#else

#if (@SIZEOF_LONG@ == 8)

typedef long              __s64; // < ------------ should long long branch

#endif /* SIZEOF_LONG_LONG == 8 */

#endif /* SIZEOF_LONG == 8 */

#endif /* SIZEOF_INT == 8 */

#endif /* __S64_TYPEDEF */

 

After I exchange the inconsist branches, all things work fine.
