How to get .o not .lo files in foo_LINK command?

[Grzegorz Jakacki]

Hi,

I am using Automake 1.6 / Autoconf 2.53 / Libtool 1.4.2.

I have a bunch of source files. I want to compile them and

  * link into executable,
  * link into library,
  * link into another executable with external linker, which
    does not understand libtool objects.

With

    $ cat Makefile.am
    SRCS = foo.cc
    bin_PROGRAMS = foo foo.pure
    lib_LTLIBRARIES = libfoo.la

    foo_SOURCES = $(SRCS)
    foo_pure_SOURCES = $(SRCS)
    libfoo_la_SOURCES = $(SRCS)

    # :GOTCHA: workaround, so that we can
    #     build targets from the same sources
    foo_CXXFLAGS = $(AM_CXXFLAGS)
    foo_pure_CXXFLAGS = $(AM_CXXFLAGS)
    libfoo_la_CXXFLAGS = $(AM_CXXFLAGS)

    foo_pure_LINK = purify g++ -o $@

the external link command is

    purify g++ -o foo.pure  libfoo_la-foo.lo

and the linker chokes on *.lo

Question: how can I get *.o files in the external linker command line?

And yet one funny thing. When in the example above I replace $(SRCS) with
explicit "foo.cc", the external link command becomes

    purify g++ -o foo.pure  foo_pure-foo.o

I do not understand why. Is this a bug? Unfortunately, this is not a viable
solution to my problem, since in my real project SRCS contains much more
than just "foo.cc", so I would rather not triplicate its whole content.

Help appreciated.

Best regards
Grzegorz
