Hi Andrew,

 

Ø  As Michael explained, DB_INSTALLS is now used for installing local copies of files from other modules, whereas DB is used for installing files that come from this source directory.

 

That is not what it says in the Application Developer’s Guide for 3.16.2, which says:

 

***************************

4.6.11 DB install files

Definitions of the form:

    DB_INSTALLS += <name>

result in files being installed to the $(INSTALL LOCATION/db directory. The file can appear with or without a directory prefix. If the file has a directory prefix e.g. $(APPNAME)/db/, it is copied from the specified location. If a directory prefix is not present, make will look in the current source directory for the file.

***************************

 

Is the current behavior documented somewhere?

 

Thanks,

Mark

 

 

 

Hi Mark,

I just tested the template file generation in asyn with this command:

 

/home/epics/devel/asyn/bin/linux-x86_64/makeSupport.pl -t streamSCPI test4

...

This is the Makefile it generated:

 

**********************

corvette:~/scratch/test4/test4Sup>more Makefile

TOP=..

include $(TOP)/configure/CONFIG

#=======================================

 

# Install .dbd and .db files

DB_INSTALLS += devtest4.db

DB_INSTALLS += $(TOP)/test4Sup/devtest4.proto

 

#=======================================

include $(TOP)/configure/RULES

**********************

The Makefile looks OK to me.  I am not sure why the proto file has an explicit path, and the .db file did not, since they are in the same directory.

The makeSupport.pl script is just copying the template files provided by Asyn and substituting macros. makeSupport/streamSCPI/_Name_Sup/Makefile template exactly matches the above. It looks like Janet made a change between Base-3.14.9 and 3.14.10 that modified the DB_INSTALLS rule to do what it does now.

It seems like DB_INSTALLS works if the file has a path, but does not work if the file is in the current directory?

As Michael explained, DB_INSTALLS is now used for installing local copies of files from other modules, whereas DB is used for installing files that come from this source directory. You may be able to use

DB_INSTALLS += ../devtest4.db

instead of DB, but that merely complicates the Makefile.

You'll need to adjust the template files in Asyn as appropriate.
