[Copying gnucash-devel.]

I'm using:

  [hampton@hampton-pc hampton]$ libtool --version
  ltmain.sh (GNU libtool) 1.4 (1.922 2001/04/25 00:05:37)

Gnucash shouldn't be trying to do this.

I don't see where libgncmod-engine.a is compiled into
libgncmod-backend-file.a.  I see the compile line, but its referencing
the .la libtool file which should convert to the .so file.

I just did a 'make clean; make' in my tree and only the following .a
files were built:

	libgncmod-test.a
	libgncmod-test-engine.a
	libgnc-test-file-stuff.a

I think this is your problem.  It would explain why you are seeing
symbols multiply defined and I don't.

No.  I think we've isolated the problem.  For some reason your copy of
libtool is building static libraries instead of shared libraries.

Rerun autogen.sh again and check the output to see if its building
static or shared libraries.

  checking whether the linker (/usr/bin/ld) supports shared libraries...
     yes
  checking how to hardcode library paths into programs... immediate
  checking whether stripping libraries is possible... yes
  checking dynamic linker characteristics... GNU/Linux ld.so
  checking if libtool supports shared libraries... yes
  checking whether to build shared libraries... yes
  checking whether to build static libraries... no

You could also try adding the --enable-shared argument to autogen.sh.

I tried using the --disable-shared argument and didn't see your problem,
but I did see the build system start directly linking in a bunch of .a
files and I got literally hundreds of errors for undefined symbols.=20
(The same 25 or 30 symbols, over and over.)

I'm reluctant to apply your patch since I can't recreate your problem
and there appears to be another explanation.  If we can't resolve this
problem, I'll apply your patch locally and test it out to see if it
causes me any problems.
