oracle的sqlldr安装报错,oracle - oracle sqlldr->未定义符号：sldext - 堆栈内存溢出

安装的oracle_client

oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm

oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm

oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm

将sqlldr文件复制到/usr/lib/oracle/11.2/client64/bin

将rdbms和nls文件夹复制到/usr/lib/oracle/11.2/client64/

设置.bash_profileexport LANG=en_US.UTF-8 export ORACLE_HOME=/usr/lib/oracle/11.2/client64 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib export NLS_LANG=KOREAN_KOREA.KO16KSC5601 export TNS_ADMIN=$ORACLE_HOME/network/admin export ORA_NLS10=$ORACLE_HOME/nls/data export PATH=$ORACLE_HOME/bin:$PATH

但是，执行ldd -r sqlldr跟随下一行

libclntsh.so.11.1 => /usr/lib/oracle/11.2/client64/lib/libclntsh.so.11.1 (0x00007f6f036bb000)

undefined symbol: sldext (./sqlldr)

.bash_profile

export LANG=en_US.UTF-8

export ORACLE_HOME=/usr/lib/oracle/11.2/client64

如何删除undefined symbol ？
