Hi Naum, Try this: modify your statement: #if defined(NAME) && defined(XXX) && (NAME == XXX) #include "include_file.h" #endif If you are wondering what is going on in your #if test, maybe this will help, from the C preprocessor document: "Identifiers that are not macros, are treated as zero." So your test... #if (NAME == XXX) ...looks like this if NAME and XXX are not defined, or one or the other or both are defined to be 0... #if (0 == 0) HTH, --Eljay
