Re: Installing cx_Oracle on AIX without using "xlc_r"

I did a test on another server with AIX as well. Python-2.7.6.tgz
downloaded a version compiled and manual.

./configure --prefix=/usr/lib/Python-2.7.6
> make
> make install
> chmod -R 777 /opt/local/


Python it works:

bash-4.2$ /usr/lib/Python-2.7.3/bin/python
> Python 2.7.6 (default, Nov 27 2013, 09:49:44)
> [GCC 4.2.3] on aix6

But installing cx_Oracle continues on failure:

bash-4.2$ /usr/lib/Python-2.7.3/bin/python setup.py install

When Python is built on aix, it also creates a wrapper for compiling C modules that can be called from Python. This is the ld_so_aix program. If you compile python with xlc, the wrapper will be created with xlc as the compiler and linker. If you compile python with gcc, it will create a wrapper using gcc. You can't use a xlc-compiled python to create gcc-compiled modules. So you either have to rebuild python with gcc and then compile cx_oracle or you have to get xlc to compile cx_oracle. Now, you can get a free trial of xlc for aix on ibm's website. Maybe that's sufficient to create a rpm you can reuse, but make sure to check the licensing terms of the trial before doing so.

Rapidly troubleshoot problems before they affect your business. Most IT

affects their revenue. With AppDynamics, you get 100% visibility into your
