[Boost-users] [Boost.Test] shared lib (.so) has no main(), static (.a) does

Hi, I'm trying out boost 1.34 and running into some troubles getting
my test programs to link.  They were working fine with 1.33.1, and
rebuilding with 1.34 now fails to find "main" in the boost unit test
framework library.  After a little investigation, I found that the .so
does not have main() in it, but the .a does.

System: suse linux 9.1
compiler: g++ 3.3.3
boost version: 1.34

I built boost by simply issuing:  ./configure && make && make install

I've searched for hints what may have changed or why it's no longer
working (that is, what I'm doing wrong) but I just don't see any
relevant documentation.  The most suspicious part is the difference
from the shared library and the archive file.

$ nm -a /usr/local/lib/libboost_unit_test_framework-gcc33-mt-d.so | grep main
00077498 d DW.ref._ZTISt12domain_error

$nm -a /usr/local/lib/libboost_unit_test_framework-gcc33-mt-d.a | grep main
00000000 V _ZTISt12domain_error

$

For a simple example:

#define BOOST_TEST_MAIN
#include <boost/test/unit_test.hpp>
BOOST_AUTO_TEST_CASE(mytest)
{
}

$g++ mytest.cpp -I $BOOST_HDRDIR -L $BOOST_ROOT/lib
-lboost_unit_test_framework-gcc33-mt-d

/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../../crt1.o(.text+0x18): In
function `_start':
../sysdeps/i386/elf/start.S:98: undefined reference to `main'
collect2: ld returned 1 exit status

Suggestions welcome.  Thanks.
