Making a 32bit with a 64bit.
lazarus / 11-Options

I am trying to compile an application to run in an XP virtual machine.

In Project Options:

I make a new build mode "32bit".

I select:
* Target OS = Win32
* Target CPU family = (Default)
* Target processor = (Default)

And I get
Error: Illegal parameter -Twin32

I assume you use a 64-bit Lazarus: do you have a i386 cross compiler
together with the units for Win32 installed? If you're on Windows you
can download the i386-win32 addon and install it.

Note you can view the supported targets by running:Code: Bash
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i fpc -itIf
it does not list WIN32 as target, then you need the addon.

Thaddy's done it again.

Nope. I have to get the addon.

Thanks both PascalDragon and Thaddy.

Looks like I have to upgrade Lazarus. Should I delete it first? I run
[yuk] Windows.

IIRC the Windows installer will detect a previous installation and ask
you whether you want to uninstall it first or do a secondary
installation, so there should be no need for you to do it manually.
HTH.

Last time I checked: no, it does not remove the hidden .lazarus
directory.

Good feedback lucamar & Thaddy.

I am using Windows, and there appears, using non microsoft software,
to be no ".Lazarus" directory.

I actually have my Lazarus application directory as C:\Lazarus, and my
projects on another drive.

Installed Lazarus 2.0.10; FPC 3.2.0; SVN Revision 63526;
x86_64-win64-win32/win64.

Installed lazarus-2.0.10-fpc-3.2.0-cross-i386-win32-win64

But "fpc -it" is not showing Win32.

Evidently something must be manually done, but where's the
instructions?

You need to use fpc -Pi386 -it, cause the default in your case is the
64-bit one and that only lists the targets of the 64-bit compiler.

Ta, I shall look into that as soon as I solve the upgrade issues.

I will have to make it an option for the project, not a global, as at
this stage, only 1 project is for XP.

----------------------------------------------------------------------

All is looking good.

I ran the -Pi386 -it command, then configured my 32bit build move in
Project Options, compiled, then copied the .exe to the XP VM, and ran
it. Looks good.

With the troubles I experienced with the Lazarus upgrade, I would
recommend deleting it first. I was jumping from ...

[at this stage I opened up an old thread, and found my profile is the
recently changed one, not the original when posted. My intention was
to get the previous versions numners of Lazarus & FPC] ...

Anyway Lazarus was 1. something.

Thanks to all.
