Hi Pierrick,
I think your problem is the path to the library, not static versus
dynamic:
TargetMon_LIBS +=
/home/epics/Software/MICESoftware/MICETrackerSoftware/.lib/libMICECoreUt
ils
make[3]: *** No rule to make target
`../../../lib/linux-x86/lib/home/epics/Software/MICESoftware/MICETracker
Software/.lib/libMICECoreUtils.a', needed by `TargetMon'. Stop.
Note that you have told it to look in
/home/epics/Software/MICESoftware/MICETrackerSoftware/.lib/libMICECoreUt
ils
but it is reporting the unfound file as:
`../../../lib/linux-x86/lib/home/epics/Software/MICESoftware/MICETracker
Software/.lib/libMICECoreUtils.a'
Which is going to be a non-existent path.
I am not sure exactly how to do this, because I have always used
libraries that were either part of the EPICS build or in standard
locations for the linker, like /usr/local/lib. But I think in your
Makefile you need to specify just the name of the library like:
TargetMon_LIBS += MICECoreUtils
and separately tell it a library path where this file is located.
