Geoff,
 I will only address the path issue, but not EPICS.
Using "sh" shell commands:
Example 1.

An absolute path (example: "/usr/local/epics/bin") is specifically
defined and works.
Example 2.
     Also the following will work:
set EPICS_DIR = /usr/local/epics
set BIN_DIR = /bin
set $PATH = $EPICS_DIR$BIN_DIR
     then:
> echo $PATH
/usr/local/epic/bin
    So if you used $PATH, you would also get to
/usr/local/epics/bin .
Example 3.
   Now if you add an external product (say in /usr/local/product/bin)
then you could:
set $PRODUCT_DIR =  $EPICS_DIR$/../product/bin
and
> echo $PRODUCT_DIR
/usr/local/epics/../product
   /usr/local/epics/../product is equal to /usr/local/product and would
work.  But, there is more chance of error.
   Just specifying set $PRODUCT_DIR = /usr/local/product reduces the
chances of making an error, especially when referencing a location
outside of your current location, in this case EPICS.
    If this seems confusing, then maybe that was my point.  Use the
simplest way that works.
Hope this helps.

Hi,
I have two environment variables that are set when I go to build a top
area, EPICS_DIR and EPICS_EXTENSIONS_DIR, in addition to
EPICS_HOST_ARCH.  I want to use these environment variables in
configure/RELEASE to specify where the external products are located.
EPICS_BASE=$(EPICS_DIR)
SYMB=$(EPICS_EXTENSIONS_DIR)
VXSTATS=$(EPICS_EXTENSIONS_DIR)
With these definitions there are environment variables missing from
configure/O.solaris-sparc/CONFIG_APP_INCLUDE.  For example when
constructing dbd files that include dbCommon.dbd the dbCommon.dbd file
is not found.
When I use absolute paths everything works.  Would someone please remind
me why I need to use absolute paths when specifying products in the
configure/RELEASE file?  Can I specify these variables in a different
location?
I'm using epics R3.14.4 on solaris-sparc.
Thanks
Geoff
