Today is 2014-05-27, today encountered a Lib problem, record again. This is a case, but also a way to solve the problem of the process.

When we use Sqlplus to log in to a UNIX database, there is a possibility of a similar problem: xxxxxx bad ELF interpreter:no such file or directory. The solution to this problem is also the problem of Lib. The normal conditions are as follows:

[Email protected] ~]# su-oracle[[email protected] ~]$ ldd ' which sqlplus ' linux-vdso.so.1 = (0x00007fff2e5f f000) libsqlplus.so =/u01/app/oracle/product/11.2.0/dbhome_1/lib/libsqlplus.so (0x00007fba1fef6000) Lib clntsh.so.11.1 =/u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1 (0x00007fba1d48b000) libnnz11.s o =/u01/app/oracle/product/11.2.0/dbhome_1/lib/libnnz11.so (0x00007fba1d0be000) libdl.so.2 =/LIB64/LIBDL. So.2 (0x0000003c93800000) libm.so.6 =/lib64/libm.so.6 (0x0000003c94400000) libpthread.so.0 =/lib64 /libpthread.so.0 (0x0000003c94000000) libnsl.so.1 =/lib64/libnsl.so.1 (0x0000003ca3000000) libc.so.6 =& Gt /lib64/libc.so.6 (0x0000003c93c00000) libaio.so.1 =/lib64/libaio.so.1 (0x00007fba1cea4000)/lib64/ld-li Nux-x86-64.so.2 (0x0000003c93400000) [[email protected] ~]$

However, sometimes the corresponding lib file may be missing.

So the solution to this problem is:

1, see the program is missing LIB files are those

2. If the corresponding Lib file is inferred, the problem of environment variable is missing or not.

3, if the Lib file is missing then need to install the appropriate package or copy the appropriate lib file. If it is an environment variable problem, it is necessary to set different environment variables for different systems.

Also for Oracle we installed the 32-bit is LIB32, is the 64-bit then is the Lib folder.

For example, here is a sample of the boot RealSync I have encountered today, similar to other programs:

Start RealSync Demo sample such as the following error:

Then for ld-linux.so.2 is the appropriate glibc.i686 for this package. So install: For example, the following:

This is no error prompt to view logs such as the following:

To view the use LIB information for this program:

To know that there are two problems at the moment, one is libnnz.so not, and the other is libclntsh.so.11.1 not. The need to do is to install the corresponding package or directly copy the corresponding LIB file to the corresponding folder.
What needs to be done now is to change the environment variables
