I have installed the DCOracle2-Beta5 product in my Zope 2.4 with Python 2.1 for Win32 plataform. However, when I run the install.py file with Python 2.1 version (and the win32 extensions installed), it shows the next error: "ERROR: DCOracle2 failed to load The most likely reason DCOracle2 failed to load is a platform binary mismatch between your version of Oracle and the version of Oracle the pre-built binary was compiled against, Oracle 8i. You can either rebuild DCOracle2 from source, or install Oracle 8i client libraries on your computer. You may be able to obtain Oracle client libraries at http://technet.oracle.com The python error message is: exceptions.ImportError: DLL load failed: Uno de los dispositivos vinculados al sistema no funciona." However, I am using the Oracle8i Enterprise Edition Release 8.1.5.0.0. Also, I have tried compile the source files, but it generates a error because it does not found the "oci.h" file. This file is not in the packaged DCO2-beta5.zip file. Could you help me about this problem? Thank you very much.
