require db template cannot be loaded properly

[jeonghanlee]

Some prequirements are expected in require.c

IOC should define in the first, and the following errors

dbLoadTemplate(moduleversion.template, "IOC=E3Test")
dbLoadTemplate: error opening sub file moduleversion.template: No such file or directory
dbLoadTemplate(iocAdminSoft.substitutions, "IOC=E3Test:IocStat")
dbl > ".//E3Test_PVs.list"

require: record E3Test:MODULES not found
require: record E3Test:VERSIONS not found
require: record E3Test:MOD_VER not found

If I set the absolute path in....

dbLoadTemplate(/epics/modules/require/0.0.1/R3.15.4/db/moduleversion.template, "IOC=E3Test")
Substitution file error: syntax error
line 1: 'record'

Here is dbl output:

(null):iocStats_VER
(null):require_VER
(null):MODULES
(null):MOD_VER
(null):VERSIONS

It was hard-coded in require.c. In order to give users to choose its own IOC variable, REQUIRE_IOC was introduced. implemented at f007423 and icshwi/require-ess@239a996
