我使用本教程中的代码来试验OCCI:
http://oradim.blogspot.com.br/2009/08/getting-started-with-occi-linux-version_16.html当我尝试运行应用程序时，它给了我以下错误:

我在ubuntu机器上运行netbeans编译。编译过程如下:
g++ -c -g -I/u01/app/oracle/product/12/dbhome_1/rdbms/public -MMD -MP -MF "build/Debug/GNU-Linux/main.o.d" -o build/Debug/GNU-Linux/main.o main.cpp

调试后，我可以看到它在这里崩溃(用户，密码和ip提交，但我使用相同的用户和密码连接到sqlplus)，但我不知道为什么崩溃:

this->passwd = "pass";
this->db = "myip:1521/orcl";
