Apple often updates their SDKs between releases of Xcode and OSes, which explains what you see here. But "MAC_OS_X_VERSION_10_5" is just a constant, it does not indicate the SDK version. The numbering is obvious, see AvailabilityMacros.h: #define MAC_OS_X_VERSION_10_0 1000 #define MAC_OS_X_VERSION_10_1 1010 #define MAC_OS_X_VERSION_10_2 1020 #define MAC_OS_X_VERSION_10_3 1030 #define MAC_OS_X_VERSION_10_4 1040 #define MAC_OS_X_VERSION_10_5 1050 So we could simplify: #if defined( MAC_OS_X_VERSION_10_5 ) && \ ( MAC_OS_X_VERSION_MIN_REQUIRED >= MAC_OS_X_VERSION_10_5 ) to: #if MAC_OS_X_VERSION_MIN_REQUIRED >= 1050 I think it is still very readable and it has the advantage of working with any SDK, even back to 10.0. Note that developers often confuse the meanings of MAC_OS_X_VERSION_MAX_ALLOWED and MAC_OS_X_VERSION_MIN_REQUIRED. To check for the 10.5 SDK use: #if MAC_OS_X_VERSION_MAX_ALLOWED To check the minimum supported OS version ("Mac OS X deployment target" build setting) use: #if MAC_OS_X_VERSION_MIN_REQUIRED So the previous conditional declaration of ResourceIndex was wrong, but adding something to the configure script is not the ideal solution in my option. For example, it breaks VTK which uses freetype but does not use freetype's configure stuff (it uses CMake). A better solution is to just test the SDK version. I have attached a patch. Suzuki-San, can you review and commit? -- ____________________________________________________________ Sean McBride, B.
