[cx-oracle-users] Python 2.5, cx_Oracle and 64 bit oracle issues

[Rajarshi G. <raj...@gm...>]

Hi, I have successfully install cx_Oracle using pip, Oracle 32 bit
libraries on OS X (10.5). While this lets me work on the command line
after setting my paths appropriately, I'd like to use it in a mod_wsgi
environment which is running in 64 bit mode. The version of Python is
a multi-architecture bundle (i386 and x86_64) so I've been trying to
get cx_Oracle to use the 64 bit libs.

But when I do

pip install cx_Oracle

with DYLD_LIBRARY_PATH point to the 64 bit version of Oracle, I see
the following during installation:

    gcc -Wl,-F. -bundle -undefined dynamic_lookup -arch i386 -arch ppc
build/temp.macosx-10.5-i386-2.5-10g/cx_Oracle.o
-L/Users/guhar/oracle/lib -L/Users/guhar/oracle/ -lclntsh -o
build/lib.macosx-10.5-i386-2.5-10g/cx_Oracle.so -shared-libgcc
    ld warning: in /Users/guhar/oracle/lib/libclntsh.dylib, file is
not of required architecture
    ld warning: in /Users/guhar/oracle/lib/libclntsh.dylib, file is
not of required architecture

It looks like gcc is forcing compilation for i386 but with 64 bit
libs. How can I indicate to pip that it should compile for x86_64?

Thanks,
