Subject: Forcing make rule in IOC Makefile

Hi,
I'm trying to add a rule to an IOC Makefile that gets executed whenever
I build the IOC. This rule should run a consistency check that should
warn IOC engineers if they forgot to explicitly specify the ASG field on
some record.

Using some regex magic, I managed to craft a rule that does so:

...
include $(TOP)/configure/RULES
#----------------------------------------
#  ADD RULES AFTER THIS LINE

.PHONY: checkasg
checkasg: FORCE
	@if grep -Pzo
'(?s)record\([^\)]+\)(?:(?!field\(ASG|record\([^\)]+\)).)*?}' $(DB) >
/dev/null ; then echo 'WARNING: Found records without access-security
group. Please explicitly specify ASG field.' ; fi
FORCE:

I can run this rule fine by saying "make checkasg". However, I would
prefer if it would run as part of "make all". I tried the force
mechanism above but it doesn't work:

/tmp/testioc/testApp/Db$ make
make -C O.linux-x86_64 -f ../Makefile TOP=../../.. \
    T_A=linux-x86_64 install
make[1]: Entering directory '/tmp/testioc/testApp/Db/O.linux-x86_64'
make[1]: Nothing to be done for 'install'.
make[1]: Leaving directory '/tmp/testioc/testApp/Db/O.linux-x86_64'

It seems like this is not compatible with the EPICS build system but I
don't understand why. Maybe the GNUMake experts can point me into the
right direction?

Thanks a lot,

Martin
