Software dependencies

As explained in Section 1.2, CORBA is used for all communications inside the platform. The implementations of CORBA currently supported in DIET is omniORB 4 which itself depends on Python.

NB: We have noticed that some problems occur with Python 2.3: the C++ code generated by idl could not be compiled. It has been patched in DIET, but some warnings may still appear.

omniORB 4 itself also depends on OpenSSL in case of you wish to secure your DIET platform. In order to deploy CORBA services with omniORB, a configuration file and a log directory are required: see Section 11.1.1 for a complete description of the services. Their paths can be given to omniORB either at runtime (through the well-known environment variables $OMNIORB_CONFIG and $OMNINAMES_LOGDIR), and/or at omniORB compile time (with the
-with-omniORB-config and -with-omniNames-logdir options.) Some examples provided in the DIET sources depend on the BLAS and ScaLAPACK libraries. However the compilation of those BLAS and ScaLAPACK dependent examples are optional.
