Re: [Mingw-cross-env-list] Issue with libboost_thread 1.44 static

[Lothar May]

Hi,

sorry for the delay. The test program is quite simple:

-- cut here --
#include <boost/thread/thread.hpp>
#include <boost/thread/tss.hpp>

boost::thread_specific_ptr<int> ptr;


void test()
{
    if (ptr.get() == 0)
      ptr.reset(new int(0));

}

int main()
{
  boost::thread thrd(test);
  thrd.join();
  return 0;
}

-- cut here --

Linking to boost_thread, you can see both kinds of errors here: If
compiling without -DBOOST_THREAD_USE_LIB, then there are linker
errors, if you compile with it, then linking fails only without the
patch.

NOTE: This problem has just been fixed upstream:
https://svn.boost.org/trac/boost/changeset/66140
It is probably best to use this patch from this link, as it contains a
little more than proposed in the ticket.

I'm sorry I cannot provide the improved build command in detail, as I
cannot access the Linux system at this time.

Regards,
Lothar
