link a new .so with an existing .so

I have an existing C module that already built libudf.so
Now I have modify this module to call a third party software function (which is new.so), and re build to target to libudf.so

I compiled that includes all header files of third party software.
Linking to new.so is also good,

But when I try to run some application to use libudf.so, It fails

Belew is my log:

Compiling ../src/udf.c on sunos5...
cc -DNNM6.2 -misalign -erroff=E_INIT_DOES_NOT_FIT -KPIC -mt -DSOLARIS -DYES_ARGS -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED=1 -D__EXTENSIONS__ -xO3 -DSOLARIS -I. -I../hdrs -I/vobs/com.pr/make.su/hdrs -I/vobs/pnm/thirdparty/ICU/unix/include -c ../src/udf.c

Linking
CC -G -misalign -L/vobs/mz.pr/libs/hp -L/vobs/new`lorder udf.o |tsort` -o libudf.so -lnew -h libudf.so
chmod 755 libudf.so

which /vobs/new stores new.so
I/vobs/pnm/thirdparty/ICU/unix/include stores header files of new

Would you help ?

lorder

LORDER(1)						      General Commands Manual							 LORDER(1)

NAME

       lorder - find ordering relation for an object library

SYNOPSIS

       lorder file ...

DESCRIPTION

       The input is one or more object or library archive (see ar(1)) files.  The standard output is a list of pairs of object file names, meaning
       that the first file of the pair refers to external identifiers defined in the second.  The output may be processed by tsort(1) to  find	an
       ordering of a library suitable for one-pass access by ld(1).

       This brash one-liner intends to build a new library from existing `.o' files.

	      ar cr library `lorder *.o | tsort`

FILES

       *symref, *symdef
       nm(1), sed(1), sort(1), join(1)

SEE ALSO

       tsort(1), ld(1), ar(1)

BUGS

       The names of object files, in and out of libraries, must end with `.o'; nonsense results otherwise.
