Framework – CERN build system
- Current CERN NFS- Makefile approach
- pro
- Standardisation
- Easy to use
- con
- Portability
- Flexibility
- Usage of absolute pathes

Framework – CERN build system
- Alternatives ?
- Usage of generalized makefile-project, which has to be located at same level then sub-project for compilation & can be used for all c/cpp-projects?
- pro /con ?
- Only local makefiles per project
- pro / con ?
- Other ideas ?

Framework – Middleware Abstraction Layer
• Encapsulation of middleware (RDA) in an additional abstraction layer
• pro
• Possibility to replace middleware
• Easy to mock rda in unit-tests
• ??
• con
• Is a replacement realistic? Only makes sense if it is lab-specific !
• A lot of work for adding an additional possibility
• ??

• current situation at GSI• OmniOrb ZeroMessageQueue
• Compatibility / API ?• Already some estimate release-date ?
• Extension of collaboration to cmw-rda• to get rid of cmw-rbac and pm dependency @GSI• to be able to use GSI-log-appender in cmw-rda• cmw-rda-core + cmw-rda-cern/gsi ?• Who to ask ?
• at CERN• at GSI
• Who will take care for the extension of the collaboration?

• cmw-stomp is default CERN log-appender. It just streams data to a defined udp-port.• currently fesa-gsi uses syslog-appender + std::out-appender for logging• cmw-stomp is still used inside fesa-core in order to send diagnostic-data to the navigator• Plan is to keep cmw-stomp, until we have a GSI log-appender
• than we can evaluate if a lab-specific replacement for the diagnostic-stream would make sense.
3rd Party – cmw-stomp

• Motivation: access the fesa-gsi codebase in svn• Who should get acc-net accounts ?• What is the current state / do we have blockers ?
