Re: Building JFFS2 on net template fails


I faced same problem before, and I solved it by modify the CYGPKG_FS_JFFS2_CFLAGS_ADD option like below.

- default_value { "-D__ECOS -nostdinc -iwithprefix include" }
+ default_value { (CYGPKG_POSIX ? "-D_POSIX_SOURCE " : "") . "-D__ECOS -nostdinc -iwithprefix include" }


I have committed a patch servals days ago:
http://sourceware.org/ml/ecos-patches/2007-01/msg00070.html
That patch also fixed other spelling mistake and compiling warnings in JFFS2 package.

The problem is in

packages/compact/linux/current/include/linux/types.h

It has

#define uint8_t cyg_uint8
#define uint16_t cyg_uint16
#define uint32_t cyg_uint32

#define int8_t cyg_int8
#define int16_t cyg_int16
#define int32_t cyg_int32

So when bsdtypes.h is included afterward, which has....

typedef	__signed char		   int8_t;
typedef	short			  int16_t;

etc, the int8_t gets replaced with cyg_int8 and you end up with
redefining the type.

The #defines need replacing with something better.
