SQL & PL/SQL

Hello,

I have 3 code files written in ProC. I have precompiled, compiled, tested them in my local environment (Windows) & they work fine. But when I try in real environment, AIX 5.3, I can precompile them. But when I try to compile & link them with the libclntsh library I get errors. I am using a Makefile but just for testing this is the command -

xlc oraProcs oraProcs.c test_curva.c lib_util.c -I $ORACLE_HOME/precomp/public -L $LIBPATH -l libclntsh.a

Error - ld: 0706-006 Cannot find or open library file: -l libclntsh.a
ld: open(): A file or directory in the pathname does not exist

where LIBPATH = $ORACLE_HOME/lib
library libclntsh.a exists in $ORACLE_HOME/lib & has the right permissions

I also tried removing the library libclntsh.a & recreating it using the command - genclntsh
When I run this command I get this warning more than once -
ld: 0711-783 Warning TOC overflow TOC size: 66888 Max size: 65536

Please let me know if u have any suggestions. Any help is appreciated. Thanks
