conditional compile else?

is there a way to say

?Win32
   function win32only()
?else
   function AllOtherPlatforms()
?

?

Const PLATFORM = "Win32"

If PLATFORM = "Win32"
...
End if

That should work? AFAIK, it will only compile if the parts of the if statement that evaluate to true.

well, yes, but I was hoping that the ? compiler directive had this functionality.

The code from zeedoktor achieves the same thing.

?Win32
	Print "Windows"
?Linux
	Print "Linux"
?MacOS
	Print "MacOS"
?

It's not like it's a lot of extra typing is it?

No, that's not, but the more code you want to conditionally compile, the more annoying it becomes.

*EDIT*

And let's imagine for a moment that BMax gets ported to WinCE and PalmOS and heck, the gameboy.

you'd then have 6 os's to do instead of 3.

working on zeedoktor's idea...

?Win 32
  Const PLATFORM=1
?Linux
  Const PLATFORM=2
?MacOS
  Const PLATFORM=3
?
If PLATFORM=1
  function win32only()
else
  function AllOtherPlatforms()
endif

Or something to that effect.

This seems to work:

?macos
	notwin32 = macos
?linux
	notwin32 = linux
?

?Win32
	Print "Windows"
?notwin32
	Print "Something Else"
?

Edit: But it doesn't

A little off topic here:

i recon someone gets it working on a Gamecube sometime (it uses the PPC processor, no? and they just managed to get linux working on a GC....)

Hey.. thats another question.. would bmax run on linux running on a mac? :S

This works:

?Win32
	Print "Hello Win32"
	Goto begin1
?
	Print "Hello Linux/MacOS"
? 
#begin1

?Linux
	Print "Hello Linux"
	Goto begin2
?
	Print "Hello Win32/MacOS"
? 
#begin2

?MacOS
	Print "Hello MacOS"
	Goto begin3
?
	Print "Hello Linux/Win32"
? 
#begin3

But it isn't pretty :)

Hi,

You're all assuming that we're going to have full access to the other machines.

Consider Perturbatio's point another way.

What if you only had a win32 pc and had friends with registered bmax to compile for linux/mac ? it would be nice to have a command that returns the id or something.

It's not essential but nice all the same.

This may be of interest:

?Debug
	Print "Debug is On!"
?

Silly question, but what does the ? do?

(And all variations)

Normally, you want to call different functions and import different libraries etc on different platforms, and ? is a preprocessor directive so anything thrown out the compiler will never see. Blocks of code wrapped in If <0> will still be parsed. ? will allow you to import different source files depending on the platform. If <Const> will not.

I believe the exes are x86 exes not ppc ones, so probably not. You might get mac exes running under mac linux? But then you may as well just run macos ;]


Why not? I still don't understand the difference. If 0=1 doesn't get compiled... Or does it? It shouldn't.

It isn't added to the EXE (AFAIK), but it IS parsed. Try to compile this:

If 0 Then (*&%*$#&%(#^#$%#$%

Further, Import must appear at the top of a source file, so:

If Win32

	Import "Win32Code.bmx"

ElseIf Linux
	
	Import "LinuxCode.bmx"

Else
	
	Import "MacOSCode.bmx"

Endif

Will not work. You can use Include in this way, though.

Fascinating. That seems totally illogical to me =]
