Yes, I have #include <atf-c.h> in my test programs.

I have two Makefile.am - one in my project's top directory and one
under src. Their contents is as follows:

$ cat ./Makefile.am
SUBDIRS = src

$ cat src/Makefile.am
CLEANFILES =

bin_PROGRAMS = countnb

countnb_SOURCES = countnb.c

testsdir = $(exec_prefix)/tests/cryptoexamples
tests_DATA = Atffile

tests_PROGRAMS = test_seed_prng test_init_bf
test_seed_prng_SOURCES = seed_prng.c test_seed_prng.c
test_init_bf_SOURCES = seed_prng.c init_bf.c test_init_bf.c

atf_run_and_report = rm -f $${fifofile}; \
        mkfifo $${fifofile}; \
        cd $${dir}; \
        cat $${fifofile} | tee $${logfile} | atf-report & \
        atf-run >>$${fifofile}; \
        res=$${?}; \
        wait; \
        echo "The verbatim output of atf-run has been saved to" \
             "$${logfile}; exit code was $${res}"; \
        test $${res} -eq 0

check-local: check-atf
.PHONY: check-atf
check-atf:
        logfile=$$(pwd)/check.log; fifofile=$$(pwd)/check.fifo;
dir=${builddir}; $(atf_run_and_report)
CLEANFILES += check.fifo check.log

installcheck-local: installcheck-atf
.PHONY: installcheck-atf
installcheck-atf:
        logfile=$$(pwd)/installcheck.log;
fifofile=$$(pwd)/installcheck.fifo; dir=$(testsdir);
${atf_run_and_report}
CLEANFILES += installcheck.log installcheck.fifo

$ /usr/bin/atf-version
Automated Testing Framework 0.5 (atf-0.5)

It seems that it is pretty old. I will upgrade my NetBSD base system
to see if I will get a newer ATF.


$ /usr/pkg/bin/atf-version
Automated Testing Framework 0.10 (atf-0.10)

Yes, these options are working.

Let me give more information: I am attempting the build the project
and build and execute its unit test on Mac OS X and on NetBSD. On Mac
OS X I run

$ ./configure CPPFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib

On NetBSD I run, as you said,

$ ./configure CPPFLAGS=-I/usr/pkg/include LDFLAGS="-L/usr/pkg/lib
-Wl,-R/usr/pkg/lib"

Obviously, I need a way to consolidate these options, but this is an
issue related with autotools and it requires more extensive reading of
autotools manual.

Yes, I played a little bit with pkg-config and PKG_CHECK_MODULES, not
with much success. Will take a deeper look tomorrow.

My miss! Actually I read about it, even took notes and then I forgot about it.
