Thanks Friends who helped me,

I have successfully compiled and implemented
FreeUDFLibC UDF Lib on Suse Linux 8.2 Pro
for FB 1.5.

If anybody interested I can send binary as well as src.
the thing I changed is make file as follows

at line no 73 (approx)

FreeUDFLibC: $(UDF_OBJs)
$(LIB_LINK) $(UDF_OBJs) -o $@ $(LIB_LINK_FLAGS) -shared

the flag -shared was added and resulting FreeUDFLibC was just
copied to the /opt/Firebird/UDF directory.

Best Regards
