Is there a preprocessor variable that can be used to identify code architecture?

[OP1]

I would like to define a variable in my code that indicates whether the code was built as a 32-bit app for XP or a 64-bit app. Is there something similar to __DATE__, __TIME__ etc. to do this, so that the preprocessor can initialize a variable containing the information I am looking for?

Thanks,

Olivier

Yes there is - _M_X64 is defined if building for Intel 64. You can see a list of all of the predefined symbols in the documentation under Building Applications > Preprocessing > Using Predefined Preprocessor Symbols.

Thanks Steve. Now I can use something like:

! Retrieve the target architecture:
#IFDEF _M_X64
TARGET_X64 = .TRUE.
#ELSE
TARGET_X64 = .FALSE.
#ENDIF

It works great!

You could also test the value of INT_PTR_KIND() for being 4 or 8.

[plain]logical, parameter :: TARGET_X64 = INT_PTR_KIND() == 8
print *, TARGET_X64[/plain]
