Re: Bug in e2db and "FATAL error"

Rozelle,

Good to hear your back in circulation. Thanks for the -if flag tip -
unfortunately, we don't have that version of sch2edif, so we have to live
with the fatal errors.

I have spent a bit of time setting up Capfast lately since we got rid of
some softlinks in our build system and I thought I might share what I have
done to deal schematic dependencies between applications.

Firstly, any dependent symbols and schematics I install into the install
tree of EPICS or the application in the
$(INSTALL_LOCATION)/templates/capfast/sym directory. I also install the
new EPICS menus in $(INSTALL_LOCATION_BASE)/templates/capfast. I chose
templates because that seemed to be the most appropriate directory in the
install tree. It doesn't really matter - it just helps if it is in a
consistent place.

Secondly, I leave the capfast install tree pristine. This should make it
easier if I update Capfast.

Then, for interactive editing I alias the various capfast tools so I can
use them interactively and pick up the correct paths:

alias xschedit 'xschedit ${CAPFAST_SYM_PATH} -k${EPICS_BASE}/templates/capfast+'
alias xsymed   'xsymed   ${CAPFAST_SYM_PATH}'

and so CAPFAST_SYM_PATH becomes very similar to a normal path that you can
add to by, for example:

setenv CAPFAST_SYM_PATH "${CAPFAST_SYM_PATH} -p+/your/app/install/templates/capfast/sym"

I must say it would be nice if Capfast would look at an environment
variable for these paths anyway, but this is a simple workaround.

Finally, I do similar things with the make rules - if I have a dependent
application I can add a new path by adding to SCH2EDIF_SYSFLAGS:

SCH2EDIF_SYSFLAGS += -p+/your/app/install/templates/capfast/sym

This seems to work reasonably well, and allows us to share between
applications with just a few simple rules in the makefiles and lines in
the overall system-wide cshrc and login files.

Cheers,

Nick Rees
