Re: base-3.15.5/templates/makeBaseApp/top/iocBoot/ioc/Makefile@Common

Andrew,

For the sake of completeness:

I restarted from scratch with 3.15.5 and got same result.

Did same with 3.15.4 and got same result.

3.15.3 works. All of this is consistent with the date of the change you indicated.

Note that if I go to iocBoot/iocmyExample and run make (GNU Make 3.82)  I get

> $ make

make: Nothing to be done for `all'

"make envPaths"  works

> $ make envPaths

perl -CSD /nfs/bbl/online/user/jad22/base-3.15.4/bin/linux-x86_64/convertRelease.pl -t /nfs/bbl/online/user/jad22/example_3.15.4 envPaths

"make clean" produces

$ make clean

make: Nothing to be done for `clean

Contents of iocboot/iocmyExample is

TOP = ../..

include $(TOP)/configure/CONFIG

TARGETS = envPaths

include $(TOP)/configure/RULES.ioc

I did  "make -d"  in iocBoot/iocmyExample  and reproduce the tail here:

The target envPaths is not considered. This used to be considered after buildInstall.

Does your Makefile still contain this line?

  TARGETS = envPaths

That's what tells GNUmake to construct that file.

That ARCH variable was explicitly removed from that template file with
this git commit:

It shouldn't be needed any more for Unix-like host targets, the envPaths
file is now architecture-neutral; my RHEL7 box happily creates it both
with and without ARCH being set. The ARCH variable is still needed to
create some of the other iocBoot/ioc files though, such as cdCommands
(used for VxWorks targets) and dllPath (Windows targets).

Not yet. This was from inside my iocBoot/iochost directory created from
the example template:
