Undefined reference problem on 1.0.9

[Jakub Zawierucha]

Hi there... this is my first battle with CommonC++ (and automake so...
don't angry :) )

When i try to use CommonC++ in my program i get error at linking stage:

address@hidden:/vol/home/t3q/src/koszty$ make
Making all in src
make[1]: Entering directory `/vol/home/t3q/src/koszty/src'
c++  -g -O2    -o koszty  Main.o -lstdc++ -lccgnu2 -lpthread -ldl
Main.o: In function `basic_string<char, string_char_traits<char>,
__default_alloc_template<true, 0> >::replace(unsigned int, unsigned int,
char const *, unsigned int)':
/usr/lib/gcc-lib/i386-linux/2.95.4/../../../../include/g++-3/std/bastring.cc:156: 

undefined reference to `ost::UnixSocket::UnixSocket(char const *, int)'
collect2: ld returned 1 exit status

make[1]: Leaving directory `/vol/home/t3q/src/koszty/src'
make: *** [all-recursive] Error 1
address@hidden:/vol/home/t3q/src/koszty$

This is my makefile.am:

address@hidden:/vol/home/t3q/src/koszty/src$ cat Makefile.am
MAINTAINERCLEANFILES = Makefile.in Makefile

CXXFLAGS = @CXXFLAGS@ $(THREAD_FLAGS)
LDADD = -lstdc++ -lccgnu2 -lpthread -ldl

noinst_PROGRAMS = koszty
#koszty_HEADERS =
koszty_SOURCES = Main.cc
koszty_LDADD = $(LDADD)

And this is code:
address@hidden:/vol/home/t3q/src/koszty/src$ cat Main.cc

#include <cc++/unix.h>

using namespace ost;
using namespace std;

int main ( int argc, char *argv )
{
    UnixSocket *usock;

    usock = new UnixSocket ("my.sock");

    delete usock;

    return 0;
}

Thanx for any help !
