hans,
i am open to whatever you would like me to try.
the results of my attempt to step through the debugger
are below. didn't seem to work.
if there is something else i can do in the debugger to provide
info i may need some guidance.

as far as linking pdftk:
in Makefile.Solaris :

CXXFLAGS= -lrt -lnsl -ldl -lgcj -lsocket -L/usr/local/lib -liconv
#CXXFLAGS= -lposix4 -lnsl -ldl -lgcj -lsocket -L/usr/local/lib -liconv

in Makefile.Base:

$(CXX) pdftk.o attachments.o report.o $(itext_libs) $(libgcj_local_libs)
$(afm_objects) -I$(java_libs_root) $(CPPFLAGS)
-L/opt/gcc346/lib/copyoflib -lgcj -L/opt/gcc346/lib/copyoflib -lstdc++
$(CXXFLAGS) -o pdftk 

i read somewhere that gcc does has issues with shared libraries so above
i copied libgcj.a and libstdc++
to a directory called copyoflib an added the -L directives.

here is what ldd says:
ldd pdftk
        librt.so.1 =>    /usr/lib/librt.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libiconv.so.2 =>         /usr/local/lib/libiconv.so.2
        libm.so.1 =>     /usr/lib/libm.so.1
        libgcc_s.so.1 =>         /opt/gcc346/lib/libgcc_s.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libaio.so.1 =>   /usr/lib/libaio.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2
        /usr/platform/SUNW,Sun-Fire-V240/lib/libc_psr.so.1

i hope this is of use, if not, i will need further instruction to take
advantage
of your assistance.

thank you for your time

It looks like the thr_create call in solaris_threads.c is failing.  A
bit of debugging to determine the errno value would be useful.

Is this really being linked against the thread library?  Or is it just
picking up a dummy thr_create() that always fails?
