Re: Channel Archiver/ Extension Build Question

[Kay-Uwe Kasemir <kasemirk@ornl.gov>]

Hi:

Well, I cannot duplicate your exact setup right now,
but for what it's worth, below is the result on a
Mac w/ R3.14.6.
Tomorrow I can check the output for some Redhat linux
and R3.14.7.

Anyway, the sequence performed by make that I get is this:
- compile several *.cpp files, FUX.cpp being the last one
- combine all the *.o into libTools.a
- build some test code, which indeed links recIoc,
  searching both the 'base' and 'extension' lib dirs,
  presumably locating recIoc in the 'base' lib dir.

The point is:
Your make's error message
"...librecIoc.a', needed by `libTools.a'"
doesn't make sense to me since libTools.a
doesn't include librecIoc.a

Well, these lines in Tools/Makefile could result in
trying to link librecIoc.a into libTools.a:

# In case of shared lib, link these:
Tools_LIBS += $(EPICS_BASE_IOC_LIBS)

... but ChannelArchiver/make.cfg should assert
that you're not trying to build shared libs:
# These are overrides for CONFIG_SITE.
SHARED_LIBRARIES = NO

Did you change that setting?
