I'm trying to figure out what configuration magic is needed to get the Boost.TR1 library working with CW-9.4. It's apparent that CW has some TR1 components already: reference_wrappers tuple shared_ptr It also appears to have function, and yet the trivial test program libs/config/test/has_tr1_function.ipp doesn't appear to compile. What about mem_fn and bind? If native versions of these aren't available then we're going to have a conflict over reference_wrapper and the ref/cref functions. There's also a strange failure for the type_traits tests which all fail with: call "c:\Programme\Metrowerks\Codewarrior\Other Metrowerks Tools\Command Line Tools\cwenv.bat" -quiet set "ERRORLEVEL=" mwcc -c -lang c++ -DTEST_STD=1 -maxerrors 5 -warnings on -maxwarnings 20 -nowraplines -g -O0 -inline off -cwd include -wchar_t on -warnings nounusedexpr,nounused -runtime dmd -RTTI on -iso_templates on "-IC:\br\results\bin\boost\libs\tr1\test" "-IC:\br\boost\boost\tr1\tr1" "-IC:\br\boost\boost\tr1\tr1\bcc32" "-IC:\br\boost\libs\type_traits\test" "-IC:\br\boost" -I- "-IC:\br\boost" -o "C:\br\results\bin\boost\libs\tr1\test\tr1_has_virtual_destructor_test.test\cw-9_4\debug\threading-multi\tr1_has_virtual_destructor_test.obj" "C:\br\boost\libs\tr1\test\type_traits\tr1_has_virtual_destructor_test.cpp" ### mwcc Compiler: # In: ..\libs\type_traits\test\has_virtual_destructor_test.cpp # From: ..\libs\tr1\test\type_traits\tr1_has_virtual_destructor_test.cpp # ------------------------------------------------------------------------- # 10: # include <type_traits> # Error: ^^^^^^^^^^^^^ # the file 'type_traits' cannot be opened even though the file type_traits is clearly in the compilers search path (other headers like <regex> and <random> appear to open OK however). Any ideas anyone? John.
