RE: StreamDevice fails to compile for RTEMS targets.

Hi Mike,

 

That error is not in StreamDevice, it is in calc.  calc depends on sscan, so you must install and build sscan before you build calc.

Subject: StreamDevice fails to compile for RTEMS targets.

 

StreamDevice 2.6 fails to compile for RTEMS targets.

The problem seems to be with the example IOC in src/StreamDeviceApp/streamApp.

We get errors like these:

/home/mikew/epics/support/calc/lib/RTEMS-beatnik/libcalc.a(swaitRecord.o): In function `special':
/home/mikew/epics/support/calc/calcApp/src/O.RTEMS-beatnik/../swaitRecord.c:553: undefined reference to `recDynLinkClear'

/home/mikew/epics/support/calc/calcApp/src/O.RTEMS-beatnik/../swaitRecord.c:911: undefined reference to `recDynLinkConnectionStatus'

etc....

However, if I set the build to avoid cross compile targets, it builds OK for the Linux host.

Also it builds OK even for RTEMS targets if I comment out CALC=.... in .../configure/RELEASE.

Wondering if anyone else has run across this and what the solution might be..
