As one may notice: I switched from -lboost_date_time to
-lboost_date_time_mt-d, but it didn't work without the "_mt-d" either.

I don't know boost very well, but that sounds like you are mixing
thread-safe and non-thread-safe code.

Yes, as far as I know _mt means multithreading. I just tried the _mt version because as gtk and thus gtkmm uses threads - I used the non-mt version before.

I've also partly reorganized my code, but only after experiencing
problems, because I thought that may help. The various *.a files are
created like this:

I'm writing on a program [C++] for about six month. Recently I tried to
switch from my hand coded makefiles to autoconf/automake.  I removed all
my makefiles, replaced them with the according's and managed
to build my program with ./configure; make after two days. So far, so
good. Now the problem is, that the resulting executable contains lot's
of bugs - bugs which didn't occur with my hand crafted make files. I
tried to track them down for the last two days, without succes. To make
that clear: I've made no modifications to my source code - I only
changed the way my code gets compiled and linked.

Additionally, I've written tests for all nontrivial core-components of
my programm. This tests work without problems - even when compiled with
with the GNU-autotools. In particular I've a test for the internals
responsible for loading/saving - and this test works. But when I try to
load a file from the main program [this works well when built with my
hand written makefiles] i get a strange segfault [gdb output]:

Check whether all code you link against is
  either completely thread-safe

Well, I've never written a mulithreaded application and as far as I'm concerned [appart from the libs I'm using] my app is single threaded.

Maybe also check that you are not by chance linking against several
pthreads libraries.


By the way, is it possible that this strange behavour is caused by variable names starting with _ ?
