我在运行应用程序时收到消息
java: symbol lookup error: /usr/java/jdk1.7.0_09/jre/lib/amd64/libJdbcOdbc.so: undefined symbol: SQLAllocEnv
应用程序的目的是使用Pentaho kettle jar文件将数据从一个服务器迁移到另一个服务器。我在目标服务器上使用Jdbc-Odbc连接。我最近从Oracles网站安装了java(jre和jdk)。当我设置
export LD_DEBUG=all
我看到以下回复

我安装unixODBC显然这些函数的实现驻留在libodbc.so(符号链接到libodbc.so.2.0.0),
nm -a /usr/local/lib/libodbc.so | grep "SQLAllocEnv"
0000000000006f30 T SQLAllocEnv
0000000000000000 a SQLAllocEnv.c
我的LD_LIBRARY_PATH中有/ usr / local / lib(我确实导出了)。我还在/etc/ld.so.conf.d中放置了一个新的配置文件并运行了ldconfig。但由于某种原因,这个功能(可能是其他功能)不会加载。

任何人都可以给我任何建议,我该如何解决这个问题。据我所知,当链接器动态解析调用时,它将使用LD_LIBRARY_PATH来搜索elf文件。它是否正确?是否有某种索引可以用于查找具有所需功能的共享库?我知道创建的ld.so.cache,但必须有一些索引,即 SQLAllocEnv - > x.so,libodbc.so等。什么使链接器在这些特定文件中查找symobols?

答案 0 :(得分:0)
此错误仅表示在默认位置找不到很少的库文件。你可以像导出LD_LIBRARY_PATH = / usr / java / latest / jre / lib / amd64那样导出它。它应该解决问题。
