Hi,
our code is actually a plug-in (first level) (with own plug-ins -
second level) for and app created with gcc 3.4 + STLport + boost
1.33.1 (boost version which we would really like to avoid because
of limited shared_ptr API). We just stepped down from the
position, where cross-compiler gcc 4.2.4 and boost 1.35.0 was used
for the first and second level plugins.
It is actually quite a Frankenstein (one of the second level
plugins is gcc 4.2 with STL (not STLport!), but should be on safe
side talking pure "C" with the rest, hopefully) and we decided to
step down and reduce the risks as much as possible and hopefully
get rid off some weird bugs (runtime linker does not unload the
first level plugin cleanly, even though it claims it does so,
which is obvious next time the plugin is loaded and link-chaos
begins).
Initially, code was written for BOOST 1.34.1 (with STL, not
STLport) and is widely used and thoroughly tested. And yes, I know
I'm talking about very old libraries.
To go back to issue, I probably don't understand your point.
1.34.1 holds declaration in header file but no definition of it??
What I'd suspect is a naming / namespace issue with the functor
allocator referenced, but this is more or less just a guess... :(
Thank you for a fast response,
Damjan

Have you checked with other platform/compiler/lib?
I will try to recover the version 1.34.1 and see what could be
wrong.
Well I have uploaded version 1.34.1 and the function is declared as
explicit thread(const function0<void>& threadfunc);
and defined as
thread::thread(const function0<void>& threadfunc)
: m_joinable(true)
{...}
and used in
thread* thread_group::create_thread(const function0<void>&
threadfunc)
{
.
std::auto_ptr<thread> thrd(new thread(threadfunc));
I don't see where is the error? Does
libboost_thread-gcc34-mt-p-1_34_1.so defines
thread_group::create_thread ?
Best,
