解决方法: (在对应的地方,将+后面的内容补充到ext3.h中
[root@localhost ext3grep-0.10.2]# vim src/ext3.h 可以参考@@后面的行号添加红色标出的内容差异(正式添加时去掉前边的加号): diff -ur ext3grep-0.10.1/src/ext3.h ext3grep-0.10.1.new/src/ext3.h --- ext3grep-0.10.1/src/ext3.h2008-04-09 11:20:31.000000000 +0000 +++ ext3grep-0.10.1.new/src/ext3.h2011-12-10 07:00:50.000000000 +0000 @@ -24,6 +24,17 @@ #ifndef EXT3_H #define EXT3_H +// this trickery needs to happen before ext2_fs is included so +// bail out if it has already been included by another path +#ifdef _LINUX_EXT2_FS_H + #error please include this file before any other includes of ext2fs/ext2_fs.h +#endif + +// some versions of the ext2 headers call this s_frags_per_group and some +// call it s_clusters_per_group, define one to the other so our code works +// with both +#define s_clusters_per_group s_frags_per_group + // Use the header files from e2progs (http://e2fsprogs.sourceforge.net) // We can use these headers and then everything named ext2 or ext3. #include <ext2fs/ext2_fs.h>// Definitions of ext2, ext3 and ext4. @@ -110,6 +121,12 @@ __u32 faddr(void) const { return i_faddr; } __u16 uid_high(void) const { return i_uid_high; } __u16 gid_high(void) const { return i_gid_high; } +#ifndef i_reseved2 + //i_reseved2 has been split into two fields in recent + //versions of the headers, luckilly we can still access + //it in one peice through the hurd side of the union + #define i_reserved2 osd2.hurd2.h_i_author +#endif __u32 reserved2(void) const { return i_reserved2; } void set_reserved2(__u32 val) { i_reserved2 = val; }
