(WIN) Add special 64bit remarks...

to adapt applications to 64 bit compilation some part of code need to be REMARKED... i've not find something like:

?Win64
  'code64
?Win32
  'code32
?

maybe it's hard to add this feature.. but maybe it's possible to add something like that: (looking at the double rem ' )

''64 print "this line is executed on 64 bit compilation"

and use some sort of Pre-Compiler that PARSE the source creating the right source for 64 compiling...

the use of the double rem --> '' can make the source compatible with old IDES.. and 32 bit stock compiler...

With NG you could also mix conditionals with normal expressions:
?linux or win64
- evaluates the following if either "linux" (32 or 64 ...does not matter) or win64

@ Preprocessor
When compiling with the NG chain (bmk/bcc) you could use the project specific pre.bmk (place it in the projects folder) and this lua file is executed before. It could adjust source files if needed. This is of course no preprocessor as you want it, but might help out in certain situations.

OMG really? thank you!

but how to manage this?

?MacOS
Import BRL.glmax2d
Import brl.freeaudioaudio
?Win32
Import brl.d3d9max2d
Import brl.directsoundaudio
Import "test.o"
Import its.printing
?win64
Import brl.d3d9max2d
Import brl.directsoundaudio
?Linux
Import BRL.glmax2d
Import brl.freeaudioaudio
Import "-ldl"
?

compiling on WIN for WIN64 i receive and error:
can't find interface for module "its.printing"
but this module is only loaded on win32...

Edited my previous post while you replied, so you might miss my preprocessor-appendix.

i tried this:

?MacOS
Import BRL.glmax2d
Import brl.freeaudioaudio
?Win32x86
Import brl.d3d9max2d
Import brl.directsoundaudio
Import "test.o"
Import its.printing
?win32x64
Import brl.d3d9max2d
Import brl.directsoundaudio
?Linux
Import BRL.glmax2d
Import brl.freeaudioaudio
Import "-ldl"
?

and WORKS on NG...
but what about using this source on standard Blitzmax (where ?Win32x86 and ?win32x64) doesn't exist? (or these commands exist?)

what can i do to make source compatible with NG and standard version of Blitzmax?

i've to do that? :

?MacOS
Import BRL.glmax2d
Import brl.freeaudioaudio
?Win32
Import brl.d3d9max2d
Import brl.directsoundaudio
Import "test.o"
Import its.printing
?Win32x86
Import brl.d3d9max2d
Import brl.directsoundaudio
Import "test.o"
Import its.printing
?win32x64
Import brl.d3d9max2d
Import brl.directsoundaudio
?Linux
Import BRL.glmax2d
Import brl.freeaudioaudio
Import "-ldl"
?

A non-existing conditional in vanilla is always "false", so not executed.

To make them work with BOTH, I had to split it into multiple files for my framework:

?Win32
Import "thisveryfile_win32.bmx"
?not win32
...
?

in that "thisveryfile_win32.bmx" I could do
?bmxng
...
?not bmxng
...
?

So in your case you could do similar. I know it is not comfortable but it allows to keep a certain level of backwards-compatibility.

In your case it would be by the way:
?win32
Import "myfile_win32.bmx"
?Linux
...

and myfile_win32.bmx then contains:
?not win32x64 'this is true on vanilla - double negation
...import the x86 files
?win32x64 'only true on NG and when 64bit
... import the x64 files
?

win32x86 is a valid option in legacy bcc.
