This is a long-standing bug in our project and I've yet to figure out
how to address it.
The project is primarily a library that once installed has a "front end"
installed in libdir and N "back ends" (linked by libtool with the
'-module' option and using libltdl for dlopen) installed in pkglibdir.
Once the package is installed running 'make check' allows the test
programs to pass. However, running 'make distcheck' results in a
failure.
For example:
make[1]: Entering directory `/home/nate/git/hlbld/hamlib-3.0~git/_build'
make check-am
make[2]: Entering directory `/home/nate/git/hlbld/hamlib-3.0~git/_build'

If I am guessing correctly, the system linker cannot find the back end
module in question (in this case 'dummy' which requires no amateur radio
hardware). How/where do I specify the directory 'make distcheck' uses?
Here is the Makefile.am fragment for this portion of the library:
lib_LTLIBRARIES += c++/libhamlib++.la
c___libhamlib___la_SOURCES = c++/rigclass.cc c++/rotclass.cc
c___libhamlib___la_LDFLAGS = -no-undefined -version-info
@ABI_VERSION@:@ABI_REVISION@:@ABI_AGE@
c___libhamlib___la_LIBADD = $(top_builddir)/src/libhamlib.la
check_PROGRAMS += c++/testcpp
TESTS += c++/testcpp
c___testcpp_SOURCES = c++/testcpp.cc
c___testcpp_LDADD = c++/libhamlib++.la
c___testcpp_LDFLAGS = @BACKENDLNK@
c___testcpp_DEPENDENCIES = c++/libhamlib++.la @BACKENDEPS@
In this case testcpp is not able to load the backend.
My Google fu left me with no answers so far. ;-)
