This happened because the compiler commands have changed since beta5. If you had uninstalled beta5 first (cleaning the configuration when asked) and then install beta6, this wouldn't have happened. Of course how could you know since I didn't mention it :roll:
To fix this, either uninstall and then re-install (suggested because this will fix other changed settings too) or do the following:
Go to advanced compiler options for VC toolkit compiler, and change the command for "Linking object files to executable" to
$linker /nologo $libdirs /out:$exe_output $libs $link_objects $link_resobjects $link_options
(add $link_resobjects)
HTH,
