求救：linux下通过OCCI连接oracle数据库报连接错误

[wrestler]

哪位高手对Linux下用OCCI连接数据库属性，我最近遇到问题，描述如下，请高手求救
1.IDE kedeveploer ,gcc++ 4.2 oracle 11g
1、我的makefile文件内容
# set the include path found by configure
INCLUDES= $(all_includes) -I/u01/app/oracle/product/11GR2/db_1/rdbms/public

# the library search path.
dbaccess_LDFLAGS = $(all_libraries) -L/u01/app/oracle/product/11GR2/db_1/lib -locci -lclntsh -L/usr/local/lib -lboost_date_time

2.当加载了lclntsh库，编译的时候就报如下错误
/home/tl/TimesTen/tt1/ttoracle_home/instantclient_11_1/libnnz11.so: undefined reference to `nzdacvalue'
/u01/app/oracle/product/11GR2/db_1/lib/libclntsh.so: undefined reference to `nzstrcpy'
/u01/app/oracle/product/11GR2/db_1/lib/libclntsh.so:
undefined reference to `nzcsf_AddtoCredStore'
/u01/app/oracle/product/11GR2/db_1/lib/libclntsh.so: undefined reference to `nzstrlen'
/u01/app/oracle/product/11GR2/db_1/lib/libclntsh.so: undefined reference to `nzu_exit_trace'
/u01/app/oracle/product/11GR2/db_1/lib/libclntsh.so: undefined reference to `nzu_init_trace'
/u01/app/oracle/product/11GR2/db_1/lib/libclntsh.so: undefined reference to `nzu_print_trace'

我百思不得期解，请高手指教 谢谢

你用的是instanceclient, 就应该reference到它的libclntsh.so，而不是你安装的11GR2中的同名库。
-L/u01/app/oracle/product/11GR2/db_1/lib这个search　path是不是应该改到instant client里的路径。

我的印象里：instantclient-basic-linux32-11.2.0.2.0.zip里头是带有这些so文件的。
