How to Cross Compile 32-Bit

[daniel_bingamon]

I want an application to be cross compiled as 32-bit so that it will run on 32-bit machines.
What to I need to do in "Project Options" to set this?

What exactly you need?
Cross-compile is a process to produce on a machine executables that will run on other machines having OS and/or processors different from the the compiling one.
PellesC actually supports only one processor family (IA-32 and IA-64), and only one OS: MS-WIN.
Because each 64 bits machine can run 32bits executables we cannot strictly speak of cross-compilation when the code is produced for a 32bits processor on a 64bits machine.
In the past, when PellesC come with ARM processors support, there was some kind of cross-compilation, but only for MS-WIN OS.

Hi Frankie:

I'm not sure what Daniel needs but I was wondering how to change an existing 64 bit project to a 32 bit project in the IDE.

How can a project be compiled for 64 bit and then, with a click of "The Magic Button" in the IDE, compile for 32 bit?

Never mind. I found it. Right click on the Project name in the project window, click on Properties, click on Project tab and set the Type in the drop down box.

If you are still using PellesC version 9 then you select x86 or x64 on the Project Options Compiler page.  Using either version there can be quite a number of code changes that will need to be made, especially if this is a windows program you are changing.  Just changing the setting from 64 to 32 or 32 to 64 won't automagically fix everything that needs to be changed.
