[lustre-discuss] Compiling lustre-2.10.6

[Tung-Han Hsieh]

Dear All,

I am trying to compile lustre-2.10.6 from source code. During
compilation, there are undefined symbols:

I searched the source code, only find the definition of LDISKFS_HTREE_EOF
in ldiskfs/ldiskfs.h:

#define LDISKFS_HTREE_EOF       0x7fffffff

but cannot find the definition of LDISKFS_HTREE_EOF_32BIT and
LDISKFS_HTREE_EOF_64BIT. Could anyone tell me how to fix this problem ?

Thanks very much.
