Hi, I have a build problem: In file included from /home/alex/l4env/include/contrib/libstdc++-v3/bits/stl_algobase.h:71:0, from /home/alex/l4env/include/contrib/libstdc++-v3/memory:53, from /home/alex/src/l4/pkg/libstdc++-v3/contrib/libstdc++-v3-4.1.0/src/allocator-inst.cc:34: /home/alex/l4env/include/contrib/libstdc++-v3/bits/cpp_type_traits.h:358:12: error: expected identifier before ‘__is_pod’ /home/alex/l4env/include/contrib/libstdc++-v3/bits/cpp_type_traits.h:358:12: error: expected unqualified-id before ‘__is_pod’ /home/alex/l4env/include/contrib/libstdc++-v3/bits/cpp_type_traits.h:371:12: error: expected identifier before ‘__is_empty’ /home/alex/l4env/include/contrib/libstdc++-v3/bits/cpp_type_traits.h:371:12: error: expected unqualified-id before ‘__is_empty’ In file included from /home/alex/l4env/include/contrib/libstdc++-v3/memory:60:0, from /home/alex/src/l4/pkg/libstdc++-v3/contrib/libstdc++-v3-4.1.0/src/allocator-inst.cc:34: /home/alex/l4env/include/contrib/libstdc++-v3/limits:1067:9: error: a call to a constructor cannot appear in a constant-expression So i can't build, hot to solve this?
