I'm looking for a way to builn a native 32bit exe on my 64bit developing machine.
Usually I would run: jx compile .\PhotoFly.jxp But that produces a 64bit version.
Any ideas how to get the 32bit version?
To build a native 32bit app on 64bit platform, you should use jx compiled for ia32 processor.
If this is on Windows, you can either use the Windows Setup (x32/x64/SM/V8) (on x64 Windows you will have an option to install x32 JXcore binaries as well) or download the exact binary e.g. Windows 32 (V8) - all available on JXcore download page.
Then you can pack the app on 64bit Windows as usual:
> c:\path_to_jx_32\jx compile .\PhotoFly.jxp
