RE: How to Compile a Custom Library

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 Pierce

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

oracle-l@xxxxxxxxxxxxxxxxx, you need to get the all header files *.h, and 
relevant *.c files, and compile against 64 bit libc, libm, etc. Sometimes, you 
may have to modify your c program as well. 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
