libJdbcOdbc SQLAllocEnv一般是未定义和动态链接

Question

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

该应用程序的目的是使用Pentaho水壶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

我安装了unixODBC,这些函数的实现明显存在于libodbc.so(libodbc.so.2.0.0的符号链接)中,

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.

也

ldd /usr/java/latest/jre/lib/amd64/libJdbcOdbc.so
        linux-vdso.so.1 =>  (0x00007fff09728000)
        libjava.so => /usr/java/latest/jre/lib/amd64/libjava.so (0x00007fb8d03ab000)
        libjvm.so => not found
        libc.so.6 => /lib64/libc.so.6 (0x00007fb8d000d000)
        libjvm.so => not found
        libverify.so => /usr/java/latest/jre/lib/amd64/libverify.so (0x00007fb8cfdfe000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007fb8cfbfa000)
        /lib64/ld-linux-x86-64.so.2 (0x000000368b000000)
        libjvm.so => not found

任何人都可以给我任何建议,我可以解决这个问题.这是我的理解是当链接器解析就可以动态地将使用LD_LIBRARY_PATH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？据我所知,被创建的ld.so.cache的,但必须有一些指标即SQLAllocEnv - > x.so,libodbc.so等.是什么让链接器在这些特定文件中查找symobols？

谢谢

此错误仅意味着在默认位置找不到几个库文件。您可以在您的情况下像导出 LD_LIBRARY_PATH=/usr/java/latest/jre/lib/amd64 一样导出它。它应该可以解决问题。
