Re: [Boost-users] [Boost.Test 1.34] Multiple instances of unit_test_log_t singleton

"Kolya Kosenko" wrote in message news:4659BEE9.9040907@gmail.com... This bug exists at msvc-6.0 and msvc-7.1 when precompiled headers is used. It is *not* exits at msvc-8.0 at all. I have no msvc-7.0 so I suppose it behavior is similar to msvc-7.1.

Also I have following linker error at msvc-6.0 when I have solved previous problem: filemain.obj : error LNK2005: "bool boost::test_tools::`anonymous namespace'::dummy_cond" (?dummy_cond@? %..\..\boost/test/unit_test_log.hpp1238016409@test_tools@boost@@3_NA) already defined in pch.obj

Do we really need anonymous namespace for this case?

I do not plan to include msvc 6.0 targeted patches, unless boost regression testing is affected.

I think it would be nice to include tests for precompiled headers in regression tests of Boost.Test library.

Every compiler means something different by this term. You can't write portable code with precompiled headers. Gennadiy
