Is there a list of $IFDEF XXXXX Declarations?

[Michael Collier]

I was wondering if there is a list of the available $IFDEF declarations?

I currently use something like

{$IFFDEF UNIX}       // mac & linux - can lazarus compile for unix?
  {$IFDEF DARWIN} // mac - powerpc & intel based
  {ELSE}                  // same as IFDEF LINUX?
  {$ENDIF}
{$ENDIF}

{$IFDEF WINDOWS} // all windows
  {$IFDEF WIN32}     // windows 32 - is there windows 64?
  {$ELSE}
{$ENDIF}

It would be helpful to know if there are others so I can include in my conditional code

e.g. maybe ANDROID , WINDOWSCE ?

function GetOsVer: string;
begin
{$IFDEF WIN32}
 if WindowsVersion = wv95 then Result:='Windows 95'
 else if WindowsVersion = wvNT4 then Result:='Windows NT v.4'
 else if WindowsVersion = wv98 then Result:='Windows 98'
 else if WindowsVersion = wvMe then Result:='Windows ME'
 else if WindowsVersion = wv2000 then Result:='Windows 2000'
 else if WindowsVersion = wvXP then Result:='Windows XP'
 else if WindowsVersion = wvServer2003 then Result:='Windows Server 2003'
 else if WindowsVersion = wvVista then Result:='Windows Vista'
 else if WindowsVersion = wv7 then Result:='Windows 7'
 else Result:='Unknown';
{$ENDIF}
{$IFDEF UNIX}
 Result:='Linux';
{$ENDIF}
end;

Basically, read the manual
http://www.freepascal.org/docs-html/prog/progap7.html#x316-331000G

Android is only experimental piggy backed on the Linux target, so that's why there is no documented define yet.

Plus, if you use LCL, there are defines which can determine LCL widgetset: LCLQt, LCLGtk, LCLGtk2, LCLWin32. I don't know about other LCL targets -- are there LCLfpGUI, LCLCustomdrawn defines?

[felipemdc]

For Android for now the project should define itself the ANDROID define, like the example does, until FPC has a more proper Android support.

I don't know about other LCL targets -- are there LCLfpGUI, LCLCustomdrawn defines?

Yes, all widgets get LCL defines

[Michael Collier]

Thanks, others may find this useful, maybe not, here is what I get..but ANDROID needs checking..does the LINUX/ANDROID part look correct, that is to say does ANDROID come under the LINUX definition? The rest I just extrapolated from the webpage //http://www.freepascal.org/docs-html/prog/progap7.html#x316-331000G

Well, this is a good question. Right now ANDROID can only appear in LINUX, but I don't know how it will be when FPC has a proper target.

Code: [Select]

{$IFDEF BSD             }    // --BSD--
    {$IFDEF SUNOS         }    // SUNOS
    {$ENDIF}

This is not correct. BSD is not defined for SUNOS. UNIX is defined for SUNOS.

I can' test BEOS but looking at the sources BSD isn't defined neither. In compiler/systems/  you'll find i_beos, i_bsd,  etc. Search for 'extradefines'.

QNX is not BSD either.

BUt better remove that from the list, afaik it hasn't been supported for 7 years or so. (was afaik never ported to the 2.0.x branch)

Ok thanks

Oh, and trunk and fixes 2.6.x support openbsd. Which is a BSD :-)

NetBSD is currently sleeping. But I believe Pierre is looking into it.    NetBSD/powerpc was quickported to 1.9.2, but not really maintained.

OpenBsd sounds interesting, I found this page to dual boot a few BSD based platforms and it mentions openBSD http://geodsoft.com/howto/dualboot/ so I may as well go ahead and install openBSD with the rest so I can test lazarus in the future?

In theory, yes. Depending on how able you are in building own FPCs (there is no release yet)

How can i find if the Linux  OS is 32 or 64 bit from compile directives. Thx.
