Hi Mike,

Take a look at streamApp/Makefile.  The version on github has these lines:

# older calc versions require sscan
#PROD_LIBS += sscan

It's complicated, because calc will build with or without sscan.  (Older calc versions could not build without sscan.)  If calc is built with sscan, anything that uses calc must link against sscan.

If your copy of stream has "PROD_LIBS += sscan" commented out, uncomment that line.

Sorry, I should have sent this to the list....

I do have sscan (and all the other dependencies, such as seq, calc, asyn, pcre) built for both the host and the RTEMS targets.

Here's my .../configure/RELEASE:

TEMPLATE_TOP=${EPICS_BASE}/templates/makeBaseApp/top
SUPTOP=/home/mikew/epics/support

SNCSEQ=$(SUPTOP)/seq
ASYN=$(SUPTOP)/asyn
CALC=$(SUPTOP)/calc
SSCAN=$(SUPTOP)/sscan
PCRE=$(SUPTOP)/pcre

EPICS_BASE=/gem_sw/epics/R3.14.12.4/base


It fails the same whether SSCAN is defined or not.
Also, as I noted, it builds fine for the Linux host, but fails for the RTEMS targets.

You don't have to build sscan if you don't need the swait record. (You probably don't.  The calcout record is better.) If you don't have the sscan module, you must comment out the line that defines SSCAN, eg.
SSCAN=$(SUPPORT)/sscan-2-10-2
in calc/configure/RELEASE.

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.

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:531: undefined reference to `recDynLinkAddInput'
/home/mikew/epics/support/calc/calcApp/src/O.RTEMS-beatnik/../swaitRecord.c:539: undefined reference to `recDynLinkAddOutput'
/home/mikew/epics/support/calc/lib/RTEMS-beatnik/libcalc.a(swaitRecord.o): In function `inputChanged':
/home/mikew/epics/support/calc/calcApp/src/O.RTEMS-beatnik/../swaitRecord.c:832: undefined reference to `recDynLinkGet'
/home/mikew/epics/support/calc/lib/RTEMS-beatnik/libcalc.a(swaitRecord.o): In function `pvSearchCallback':
/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..
