Hi Heinz

 I don't think I understand your question fully, but the following way

I recently implemented a makefile rule into ESS EPICS building system to

identify many variables. I've found it from the reference [1] such as

print-%:
	@echo $* = $($*)
	@echo $*\'s origin is $(origin $*)

  You can add them into your makefile rule, then it returns

  $ make print-EPICS_VERSION_STRING
EPICS_VERSION_STRING = EPICS Version 7.0.3
EPICS_VERSION_STRING's origin is file

  I hope this may match your question.

  Best,
  Han

It was more of a general question how to simple debug the "make”.

These .rel entries no longer exist for my RTEMS5:

...
#--------------------------------------------------
# Operating system flags
ifneq ($(RTEMS_SERIES),5)
OP_SYS_LDLIBS += -lrtemsCom -lc -lrtemscpu -lCom -lnfs -lm
endif
ifeq ($(RTEMS_SERIES),5)
OP_SYS_LDLIBS += -lrtemsCom -lnfs -ltftpfs
endif

OP_SYS_LDFLAGS_posix += -u POSIX_Init
OP_SYS_LDFLAGS_kernel += -u Init \
                  $(PROJECT_RELEASE)/lib/no-dpmem.rel \
                  $(PROJECT_RELEASE)/lib/no-mp.rel \
                  $(PROJECT_RELEASE)/lib/no-part.rel \
                  $(PROJECT_RELEASE)/lib/no-signal.rel \
                  $(PROJECT_RELEASE)/lib/no-rtmon.rel

OP_SYS_LDFLAGS += $(CPU_CFLAGS) $(OP_SYS_LDFLAGS_$(OS_API))
...

Viele Grüße

I need to create a reasonable configure/os/CONFIG.Common.RTEMS-mvme2500

Is there a simple debug possibility to follow or test the generation of flags like OP_SYS_LDFLAGS etc.?

Are you asking about the .rel entries in configure/os/CONFIG.Common.RTEMS ?

OP_SYS_LDLIBS += -lrtemsCom -lc -lrtemscpu -lCom -lnfs -lm
OP_SYS_LDFLAGS += $(CPU_CFLAGS) -u Init \
                 $(PROJECT_RELEASE)/lib/no-dpmem.rel \
                 $(PROJECT_RELEASE)/lib/no-mp.rel \
                 $(PROJECT_RELEASE)/lib/no-part.rel \
                 $(PROJECT_RELEASE)/lib/no-signal.rel \
                 $(PROJECT_RELEASE)/lib/no-rtmon.rel

I have occasionally wondered what when into selecting them, though unfortunately never
long enough to dig through the RTEMS documentation.
