how to link without using ld -rpath

Hello,
I'm tryign to compile a sample code which uses OTL(Oracle, Odbc and DB2-CLI Template Library Programmer's Guide). I get this error while compiling the source file:

Code:

[hd@mahzen otl]$ g++ foo.cpp -o foo -I /tmp/  -I$ORACLE_HOME/rdbms/demo -I$ORACLE_HOME/rdbms/public -L$ORACLE_HOME/lib/ -lclntsh
/usr/bin/ld: warning: libnnz10.so, needed by /usr/lib/oracle/xe/app/oracle/product/10.2.0/server//lib//libclntsh.so, not found (try using -rpath or -rpath-link)

libnnz10.so exists in the -L path but it complains about it.
I can't understand how to use -rpath or -path-link. I do not link the files with ld, so how can I use these options? In man page of g++ there is not an option named 'rpath'. Is it possible to pass an option to g++ to do the same thing?

Thanks.

Hello,
I've solved the problem.
Adding -lnnz10 is needed to link correctly.

chrpath

CHRPATH(1)						 change rpath/runpath in binaries						CHRPATH(1)

NAME

       chrpath - change the rpath or runpath in binaries

SYNOPSIS

       chrpath [ -v | --version ] [ -d | --delete ] [ -r <path> |  --replace <path> ] [ -c | --convert ] [ -l | --list ] [ -h | --help ] <program>
       [ <program> ... ]

DESCRIPTION

       chrpath changes, lists or removes the rpath or runpath setting in a binary.  The rpath, or runpath if it is present, is where  the  runtime
       linker should look for the libraries needed for a program.

OPTIONS

       -v | --version
	      Display program version number

       -d | --delete
	      Delete current rpath or runpath setting

       -c | --convert
	      Convert the rpath setting into a runpath setting

       -r <path> | --replace <path>
	      Replace current rpath or runpath setting with the path given

       -k | --keepgoing
	      Do not fail on first error, but process all arguments before returning the error.

       -l | --list
	      List the current rpath or runpath (default)

       -h | --help
	      Show usage information.

EXIT STATUS

       0      If all operations were successful

       >0     if one of the operations failed.	A failing operation terminates the program unless -k is specified.
