When I try to link a test suite I get this:
ld: multiple definitions of symbol boost::test_tools::(anonymous namespace)::check_is_close mspathCEntry_test.o definition of boost::test_tools::(anonymous namespace)::check_is_close in section (__DATA,__data) ModelBuilder_test.o definition of boost::test_tools::(anonymous namespace)::check_is_close in section (__DATA,__data) ld: multiple definitions of symbol boost::test_tools::(anonymous namespace)::check_is_small mspathCEntry_test.o definition of boost::test_tools::(anonymous namespace)::check_is_small in section (__DATA,__data) ModelBuilder_test.o definition of boost::test_tools::(anonymous namespace)::check_is_small in section (__DATA,__data) LinearProduct_test.o definition of boost::test_tools::(anonymous namespace)::check_is_close in section (__DATA,__data) LinearProduct_test.o definition of boost::test_tools::(anonymous namespace)::check_is_small in section (__DATA,__data) .....
This is with boost 1.33 on Darwin/OS-X. The same code was building OK with the 1.31 libraries (and 1.32 on linux, I think). I'm using libtool. Here's the makefile
I remember seeing similar report recently. As it clear from error message linker complains about multiple definitions for symbols in anonymous namespace. This looks like compiler bug. If you know any workarounds please share them with us. Gennadiy
