Experimental Physics and Industrial Control System

Hi William,
If you edit the Makefile which creates the library and set SHARED_LIBRARIES=NO that will tell the build system to not generate any lib*.so files when building that library. The IOC-generating app will still
need to link with the shared libraries from upstream (snmp etc.), but it sounds like that would work for you.

Thanks.
Its a support library as far as I can tell.

I think renaming to snmpSup is more self-explanatory, that way the Makefile stays default ... nobody reads Makefiles, or check for irregularities. :>
another quick question: how can I tell EPICS to static compile the support library?
It uses some system library that needs additional compiler flags, and I would have to repeat them in the IOC-generating App...
cheers!

my main App is called IOCINFRAApp, the support App is called snmpApp.
the build system now tries to compile IOCINFRAApp first, and fails
because a dbd file from snmpApp is not yet available.
I've renamed my snmpApp to 0snmpApp and it works, but thats too hacky in
my eyes.
Is there some more elegant way to achieve that snmpApp gets built before
IOCINFRAApp ?
There are applications that generate IOCs, and there are support applications that provide things (libraries, templates) to be used by IOC-creating apps.
If the IOC-creating kind are called *App and the support applications are called *Sup, the default order (first *Sup, then *App) will work.
You can always declare a dependency that is not covered by the default build order in the Makefile. In your case,
IOCINFRAApp_DEPEND_DIRS += snmpApp
