我正在尝试使用occi连接到oracle但没有成功。
我下载并解压缩了：
sqlplus连接好数据库。
我尝试用以下代码编译我的代码：
g++ -o target/benefits_select benefits_select.cpp -L/data/etc/oracle/instantclient_11_2 -I/data/etc/oracle/instantclient_11_2/sdk/include -locci
我得到以下结果：

如果我在最后没有-locci的情况下运行它，我会得到：
undefined reference to `typeinfo for oracle::occi::SQLException`
希望有人可以提供帮助

这个问题再次发生在我身上，但我已经解决了。 libocci.so是一个oracle库，所以你把它的目录添加到你的-I选项中，这是正确的，但libocci.so需要依赖libzzn11.so和libclntsh.so，所以你应该添加两个库RIGHT到libocci.so。 例如-locci -lzzn11 -lclntsh

我继承了一个项目并且最近遇到了同样的问题。以上回复都没有真正帮助我解决它。这是我的步骤：
g ++（Ubuntu 4.8.4-2ubuntu1~14.04.1）4.8.4
项目拒绝使用原始设置进行链接（请注意链接顺序，这很重要）＆＃34; -L $ ORACLE_HOME / lib -lclntsh -locci＆＃34;用：
/usr/lib/oracle/12.1/client64/lib/libocci.so: undefined reference to `OCILobGetLength' /usr/lib/oracle/12.1/client64/lib/libocci.so: undefined reference to `OCILobArrayWrite' /usr/lib/oracle/12.1/client64/lib/libocci.so: undefined reference to `OCIPAnyDataSetInd' ......
$ nm -C libocci.so | grep OCILobGetLength
U OCILobGetLength
U means symbol is used in libocci.so, but not undefined there.
$ nm -C libclntsh.so | grep OCILobGetLength
000000000052e610 T OCILobGetLength
00000000012120e0 T OCILobGetLength2
这里定义了它。
我只是切换了链接顺序，并将其与＆＃34; -L $ ORACLE_HOME / lib -locci -lclntsh＆＃34;

将-locci -lclntsh放在最后，并添加-m64 on g ++ 4.8 on 64位Ubuntu 14.04 LTS
g ++ 4.4并不关心你把-locci -lclntsh
放在哪里答案 3 :(得分：-1)
它看起来英文版Ubuntu 14.04 LTS不需要-lzzn11，至少在我的测试中，但你需要安装 apt-get install libaio1 ，因为64位 - oracle即时客户端11.1 .0.7.0依赖于异步IO lib
