Re: Sequencer build rules

[Janet Anderson <jba@aps.anl.gov>]

Hi Benjamin,

I think it would be ok to change TOP to INSTALL_LOCATION  in Bruce's version of the code and include it in the next
sequencer release. To use the snc tool, the build needs to know its location. In Bruce's code, if SNCSEQ or SEQ is defined
we are building a module or ioc-application which has defined the sequencer in its RELEASE file using SNCSEQ or SEQ,
and the snc tool will be found in the SNCSEQ or SEQ bin directory. Otherwise we are building the sequencer module
and the snc tool will be found in the INSTALL_LOCATION bin directory.

Hi Janet, Andrew, etc

recently there was mention of a build problem when using epics base >=
3.14.12 and user defined rules. A solution was proposed by Bruce Hill:

We ran into this problem recently, trying to build std-2-9
with seq-2.1.2 and fixed it in the seq configure/RULES_BUILD.
It looked to me like it resulted from RULES_TOP not being
defined by base starting w/ R3-14-12.   This kept SNC from
being defined correctly in seq/configure/RULES_BUILD.

There's probably other ways to solve this, but we got it to
work with the attached patch, also shown below.
    

For better comparison, here is the current (seq-2.1.4) version:

ifdef RULES_TOP
 # EPICS base R3.14.7 and later
 SNC = $(RULES_TOP)/bin/$(EPICS_HOST_ARCH)/snc$(HOSTEXE)
else
 # EPICS base R3.14.6 and earlier
 ifndef SNC
  SNC = $(SNCSEQ_HOST_BIN)/snc$(HOSTEXE)
 endif
endif

and this is Bruce's version:

ifdef SNCSEQ
 SNC = $(SNCSEQ)/bin/$(EPICS_HOST_ARCH)/snc$(HOSTEXE)
else
 ifdef SEQ
  SNC = $(SEQ)/bin/$(EPICS_HOST_ARCH)/snc$(HOSTEXE)
 else
  SNC = $(TOP)/bin/$(EPICS_HOST_ARCH)/snc$(HOSTEXE)
 endif
endif

Should I include this change in 2.1.5?

Janet, is this how I should do it?

Cheers
Ben

Thanks Mark,

I tried the latest version of sequencer (R2.1.4), which did not quite
build correctly.  I did not think that mattered.  I now have regressed
to an earlier version of sequencer (R2.0.12) and std built without
errors.

I will look again at the R2.1.4 version of sequencer, see if I can fix
that.

Thanks again,

Zen

femto is an SNL program.  Do you have the sequencer in your
configure/RELEASE file in std?

I did not try building on other architectures, so I don’t know the
extent of my problem.

What am I missing on this computer?



Thanks for any help,
