Hi,

 CROSS_COMPILE_TARGET_ARCHS in base 3.14.11 may be wrong. I set it to

"linux-x86".

 As I set it to "linux-386", envPaths is generated in

myapps/iocBoot/iocmyapps by make.

 Whatever CROSS_COMPILE_TARGET_ARCHS is set to in base 3.14.8.2, envPaths

will be generated.

   I think the difference is in the file RULES.ioc .

 The 7.1 section of EPICS Application Developer’s Guide has the

following:

 "The envPaths file is automatically generated in the IOC boot directory

and defines several environment variables that are useful later in the

startup script" .

    There isn’t envPaths in iocBoot after ‘make’.

The envPaths file is created in the iocBoot/iocmyapps directory, can you
please confirm whether it is or is not present there?

If you read some documentation that implied it would appear directly in the
iocBoot directory would you please tell us where you read it, as it needs to
be corrected.

    No error happened in compiling. Only:
    make[2]: Entering directory ‘.../apps-11/iocBoot/iocmyapps’
    make[2]: Nothing to be done for ‘install’
    make[2]: Leaving directory  ‘.../apps-11/iocBoot/iocmyapps’

    The Makefile in iocBoot/iocmyapps :
    TOP=../..
    include $(TOP)/configure/CONFIG
    ARCH=linux-x86
    TARGETS=envPaths
    include $(TOP)/configure/RULES.ioc

    The base is built for linux-x86.

If EPICS_HOST_ARCH is linux-x86 that Makefile should result in the envPaths
file being created if it doesn't already exist.  There are a number of ways
where misconfiguration of your application could cause problems but I can't
think of any that would cause the build to complete like you show above.
