I'm creating a library libgdata that has some tests and non-installed programs. I am running into the problem that once I've installed the library once, the programs seem to be linking to the installed version and not the local version in ../src/libgdata.la any longer.

What could cause this? Am I doing something horribly wrong?

Here is what my test/Makefile.am looks like:

INCLUDES = -I$(top_srcdir)/src/ -I$(top_srcdir)/test/

# libapiutil contains all of our dependencies!
AM_CXXFLAGS = $(APIUTIL_CFLAGS)
AM_LDFLAGS = $(APIUTIL_LIBS)

LDADD = $(top_builddir)/src/libgdata.la

noinst_PROGRAMS = gdatacalendar gdatayoutube

gdatacalendar_SOURCES = gdatacalendar.cc

gdatayoutube_SOURCES = gdatayoutube.cc

TESTS = check_bare

check_PROGRAMS = $(TESTS)

check_bare_SOURCES = check_bare.cc

(libapiutil is another library that has some helper stuff for dealing with libcurl and libxml++)

So, for instance, if I run the tests without having installed anything, everything works fine. I can make changes locally and they are picked up by these programs right away.

If I install the package, these programs will compile (it seems like it does actually look locally for the headers), but once I run the program it complains about missing symbols.

As far as I can tell, it is linking against the newly built library (../src/libgdata.la) based on the make output, so I'm not sure why this would be happening. If i remove the installed files, the local changes to src/* are picked up just fine.

I've included the make output for gdatacalendar below.

creating gdatacalendar

Help. :)

UPDATE

I get the following messages when I try to run the calendar program when I've added the addCommonRequestHeader() method to the Service class after I had installed the library without the addCommonRequestHeader() method.

/home/altern8/workspaces/4355/libgdata/test/.libs/lt-gdatacalendar:
symbol lookup error:
/home/altern8/workspaces/4355/libgdata/test/.libs/lt-gdatacalendar:
undefined symbol:
_ZN55gdata7service7Service22addCommonRequestHeaderERKSsS4_

Eugene's suggestion to try setting the $LD_LIBRARY_PATH variable did not help.

UPDATE 2

I did two tests. First, I did this after blowing away my dev-install directory (--prefix) and in that case, it creates test/.libs/lt-gdatacalendar. Once I have installed the library, though, it creates test/.libs/gdatacalendar instead. The output of ldd is the same for both with one exception:

# before install
# ldd test/.libs/lt-gdatacalendar
libgdata.so.0 => /home/altern8/workspaces/4355/libgdata/src/.libs/libgdata.so.0 (0xb7c32000)

# after install
# ldd test/.libs/gdatacalendar
libgdata.so.0 => /home/altern8/workspaces/4355/dev-install/lib/libgdata.so.0 (0xb7c87000)

What would cause this to create lt-gdatacalendar in one case but gdatacalendar in another?

The output of ldd on libgdata is:

altern8@goldfrapp:~/workspaces/4355/libgdata$ ldd /home/altern8/workspaces/4355/libgdata/src/.libs/libgdata.so.0
