I think I know what is going on here. A look at PalmOS.pch shows that it is
trying to define the target location for the precompiled headers using Mac
OS-style pathnames i.e.
#if EMULATION_LEVEL == EMULATION_NONE
#pragma precompile_target ":Obj:PalmOS_Headers" // Mac OS-style pathnames
#else
#pragma precompile_target ":Obj:PalmOS_Headers_Sim" // Mac OS-style
pathnames
#endif
Previously CW on Windows used to use Mac OS-style paths for such things as
defining the precompiled header path and access paths. However, as part of
the de-Mac-izing of Windows CW, one of the things that occurred in R6 was
that CW now uses Windows native pathnames (c:\program files\metrowerks). I
didn't dig too deeply but if you change the #pragma precompile_target to use
a Windows pathname it should work. Note that you have to change both targets
(simulator and device) or the compiler will continue to give you the error.
You could do something like:
#if EMULATION_LEVEL == EMULATION_NONE
#pragma precompile_target "Obj/PalmOS_Headers" // now Windows-native paths
#else
#pragma precompile_target "Obj/PalmOS_Headers_Sim"
#endif
Hope this helps.
