libocci.so：未定义的引用

Question

我正在尝试使用 occi 连接到 oracle，但没有成功。

• 操作系统 = Ubuntu 14.04 LTS
• g++ = g++ (Ubuntu 4.8.2-19ubuntu1) 4.8.2
• Oracle 客户端 = 11.2.0.3

我下载并解压：

• Instantclient-basic-linux.x64-11.2.0.3.0.zip
• Instantclient-sdk-linux.x64-11.2.0.3.0.zip
• Instantclient-sqlplus-linux.x64-11.2.0.3.0.zip

sqlplus 可以很好地连接到数据库。

我尝试编译我的代码：

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：

我继承了一个项目，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

该项目拒绝使用原始设置链接（注意链接顺序，这很重要）“-L$ORACLE_HOME/lib -lclntsh -locci”：

/usr/lib/oracle/12.1/client64/lib/libocci.so：未定义对`OCILobGetLength'的引用
/usr/lib/oracle/12.1/client64/lib/libocci.so：对`OCILobArrayWrite'的未定义引用
/usr/lib/oracle/12.1/client64/lib/libocci.so：对`OCIPAnyDataSetInd'的未定义引用
......

$ nm -C libocci.so | grep OCILobGetLength
                 U OCILobGetLength


U 表示在 libocci.so 中使用了符号，但在那里不是未定义的。


$ nm -C libclntsh.so | grep OCILobGetLength
000000000052e610 T OCIlobGetLength
00000000012120e0 T OCIlobGetLength2

这是它定义的地方。

我只是切换了链接顺序，它与“-L$ORACLE_HOME/lib -locci -lclntsh”链接

由于这个https://wiki.ubuntu.com/NattyNarwhal/ToolchainTransition可能出现上述问题
