Hi Mark,
I'd pretty much reached the conculsion that it was beyond my scope as a DBA to recompile this object, but you have pointed me in the right direction. I'll try to get a developer or UNIX admin to give me hand.
Thanks for your help!

Vicki,
The error is “wrong ELF class: ELFCLASS32“. This means that you’re trying to use a 32-bit library, and it’s not working. Almost certainly, the program that’s attempting to run, which is encountering this error, is a 64-bit binary. A 64-bit binary *must* use 64-bit libraries. You need to locate and install the 64-bit version of this library. If this library is custom code, then, as previously suggested, you’ll need to re-compile it from source code. This should be a pretty easy task for an experienced C programmer, but is non-trivial, and probably beyond the scope of something I could talk you through in email.
Very briefly, you’ll need:
1.) A C compiler. Gcc is a popular choice these days, but your OS may provide a proprietary one as well. (Type ‘which cc’ or ‘which gcc’ to see if one is installed.) 2.) All the source code for the library. This will generally be all the *.h and *.c files. 3.) A make file, to help build the library. (Optional, but helpful, particularly if you have multiple *.c files that make up your library.)
Other possibly helpful commands:
‘file’, will tell you if a particular binary, object or shared object file is 32 or 64 bit. (‘file /path/to/your/binary/or/object/file’)
‘ldd’, (list dynamic dependencies), will tell you if a particular binary is missing any dynamic library dependencies.
Hope that helps,
-Mark

When I try to start the Apps services after the clone, I get an error regarding this library: ld.so.1: ps: fatal: /erp/11.5.10/appltop/cust_stuff/fnd/bin/libopenlibname.so: wrong ELF class: ELFCLASS32If I don't need to recompile the library, then do you know what is causing the error? And how do I fix it? Thanks!Vicki Pierce

Just leave the 32 bit so file like it as, since 64 bit solaris 10 contains both 32 bit n 64 bit libc, etc.

We moved our Oracle Apps software to a new 64-bit Solaris 10 server; there is a custom library (.so file) that is still in 32-bit mode. I need to compile it so that it is 64-bit. How do I go about doing that? RDBMS version 9.2.0.7; Apps version 11.5.10.2 Thanks in advance!Vicki Pierce
