Hi Francoise,
Your vpath line in RULES.Db should look like this:
vpath %.db $(USR_VPATH) $(GENERIC_SRC_DIRS) $(dir $(DB)) $(RELEASE_DIRS_DB)

with RELEASE_DIRS_DB defined in CONFIG_APP_INCLUDE as
RELEASE_DIRS_DB  += $$(wildcard $$(strip $$($(1)))/db)

I've also attached a patch file with all the changes needed for this
to work for db files, dbd files, and template files.
You should be able to apply the patch from your base $TOP/configure directory via

% patch -i db-dependencies.patch

Regards,
- Bruce

Hi,

I tried to understand what difference between 3.14.12 and 3.14.12.2 could explain the emergence of this db dependencies problem.

If I look at the dependencies file (O.linux-x86/dbfile.db.d) generated by makeDbDepends.pl, with 3.14.12 this file contains no dependency while it contains all the db dependencies with 3.14.12.2. In fact the script makeDbDepends.pl has been changed. And the problem arises because the script now works!

Then I tried to modify the file RULES.Db so that the make command looks for db dependencies in $(TOP)/db:

-vpath %.db $(USR_VPATH) $(GENERIC_SRC_DIRS) $(dir $(DB))
+vpath %.db $(USR_VPATH) $(GENERIC_SRC_DIRS) $(dir $(DB)) $(TOP)/db

But this creates a circular dependency problem and it doesn't work.

I hope this problem will be solved. Meanwhile I run 'make rebuild' as suggested by Emma. I could also remove the dependencies file.

Regards,
Françoise.

Hi Francoise,
Actually, now that you mention it, I only noticed this problem after I merged the 3.14.12.2 updates and the rules-db patch into our 3.14.12 base.

I haven't tried Ralph's one-liner perl fix, but the patch I
posted 2/17 works with our 3.14.12.2.   Just be sure to
get it from the original 2/17 post, as the quoted version in the replies below has extra linefeeds from being wrapped.

If it still doesn't work for you, take a look at the<db_substitution_filename_root>.db.d files created in the O.<target_arch>   directory.

It may also help to see what the generated RELEASE_DIRS_DB variable looks like, which you can do by adding these lines to the end of your Db/Makefile.

# After the include of $(TOP)/configure/RULES
install:   showvars
showvars:
       @echo RELEASE_DIRS_DB=$(RELEASE_DIRS_DB)

The character before the "@" must be a tab.
Then "make" or "make install" will print the value of RELEASE_DIRS_DB which should be a list of all the target db directories for the modules your ioc depends on.

If all else fails, try "make -d>   make.log" and examine the resulting make.log file which should show make searching for the missing db template in each directory on it's vpath.
That vpath should include the directories in $(RELEASE_DIRS_DB).

Regards,
- Bruce

Hi,
I have exactly the same problem since I started using EPICS Base R3.14.12.2. I never had this problem before with R3.14.12.

None of the solutions discussed here works with R3.14.12.2. I also applied the patch contained in the R3.14.12.2 known problems without success.

Cheers,

You can also try creating the dependencies correctly, e.g. by putting

$(COMMON_DIR)/%.db$(RAW)$(DEP): %.substitutions
          @$(RM) $@
          $(PERL) -e 'undef $$/; $$_=<>;
@d=m/(?:^|})\s*file\s+\"?([^\"{\s]*)\s*\{/mg; print
"$(COMMON_DIR)/$*.db$(RAW): @d\n";' $<   >   $@.tmp
          $(MV) $@.tmp $@

or something functionally equivalent into your RULES file.

Amazing how perl turns everything into an obvious one-liner, isn't it?

Cheers,
~Ralph

Hi Bruce,

Good timing - I just ran into the same problem today!  I agree, it's a pain to have to run 'make rebuild' every time.  Thanks for the patch, that works for me too.

Cheers,

Subject: Build problem with db dependencies

Has anyone else run into a build dependency problem with base-3,14,12?

What I've been finding is that I can build an IOC or module that
depends on *.db or *.template files from another module successfully
the first time, but it fails on subsequent builds.

Example build output:

The first build succeeds because RELEASE_DBFLAGS has a list of -I
directives which includes the released iocAdmin module's db dir, so
msi is able to use that to successfully build my iocAdmin.db file.

The problem arises because the first build also creates a dependency
file for iocAdmin.db using makeDbDepends.pl that looks like this.

% cat O.linux-x86_64/iocAdmin.db.d
../O.Common/iocAdmin.db: ioc.db access.db iocCluster.db
../O.Common/iocAdmin.db :


Subsequent builds fail because ioc.db is over in the released
iocAdmin module's db dir, which doesn't end up on the vpath for .db files.

I think I have a fix for it, but I can't figure out why this hasn't
been a problem for us and others before now.

I'd like to avoid customizing my base configure files to the extent
possible, but these changes seem to fix the problem.
