hi,
i need some help with resolving issue #7482: for some reason it seems to build a static libboost_atomic, although it has to be a shared library.
Well, static build is default in windows. But link=shared works.
could someone with more insights in this platform have a look, what's going wrong (and why the library is static)? unfortunately i neither have access to mingw, nor am i too familiar with the boost build infrastructure ...
This is not a Boost.Atomic issue. The problem is that --layout=system is broken on Windows. Rationale: Boost.Build (in $BOOST_ROOT/boostcpp.jam) defaults to build both release and debug variants of each library on Windows. Requiring system layout ends up with the _same_ name for the release and debug libraries on Windows. This happens for msvc too. This triggers the error reported in #7482. Explicitly specifying "--layout=system release" or "--layout=system debug" will make the problem go away. I'm not sure how/if this problem can be intercepted in boostcpp.jam You should be able to reproduce this on Linux by requesting both debug and release variants with "--layout=system debug,release". Hope this helps, Yours Jürgen -- * Dipl.-Math. Jürgen Hunold ! juergen.hunold@gmx.eu * voice: 0049 4257 300 !
