You built your sequence program "standalone", i.e. it is run as a
separate process not as part of an ioc application. Uncomment the lines
 example_DBD += sncExample.dbd
 example_SRCS += sncExample.stt
 example_LIBS += seq pv

Hello,

please let me ask a question of a beginner. I tryed the example
applications of baseR3.14.6 on SUSE linux 9.0. Everythink works well.
Now I tryed to change the name of the Sequencer program to find out,
how I can install my own program. For this I did the following:
coppy "sncExample.stt" to "sncProgram2.stt" and change the first line to:
program sncProgram2
changed the "Makefile" in exampleApp/src/    to:
ifneq ($(SNCSEQ),)
   # This builds sncExample as a component of example
#    example_DBD += sncExample.dbd
#    example_SRCS += sncExample.stt
#    example_LIBS += seq pv
   # The following builds sncProgram as a standalone application
   PROD_HOST += sncProgram2
   sncProgram_SNCFLAGS += +m
   sncProgram_SRCS += sncProgram2.stt
   sncProgram_LIBS += seq pv
   sncProgram_LIBS += $(EPICS_BASE_HOST_LIBS)
endif
changed the last line of "st.cmd" to: seq sncProgram2,"user=wehlerHost"
running "make" I get the following error message:

The same message arises when I build the directory structure with
..../makeBaseApp.pl -t caClient caClient
Can someone explain me what I did wrong?
Thanks in advance
